Flowers of Hellebores (genus Helleborus) are a welcome sight when they bloom in late winter to early spring, sometimes while the ground is still covered with snow. Different varieties of the Hellebore plant offer a range of flower colors, from white to black. One of the earliest blooms spotted in many areas, nodding hellebore flowers are often fragrant and long-lasting.
Growing Hellebores is a worthwhile task for the gardener. Aside from lovely and unusual flowers, the Hellebore plant has attractive green foliage that is aesthetically pleasing in the landscape. Once established, Hellebore care is minimal. This herbaceous or evergreen perennial is disliked by deer and other animal pests prone to munching on plants. All parts of the Hellebore plant are poisonous, so take care to keep children and pets away.
Growing Conditions and General Care When planting from seed or division, place the Hellebore into well-draining, organic soil in a filtered sun or shady location. The Hellebore plant will return for many years; make sure the space will accommodate growth and has proper sunlight. Hellebores need no more than a few hours of dappled light and grow successfully in shady areas. Plant the Hellebore under deciduous trees or scattered through a woodland garden or shaded natural area.
Soaking the soil in which the Hellebore is growing helps the Hellebore plant to look its best. Hellebore care includes removal of older leaves when they appear damaged. Care for Hellebores should also include careful fertilization. Too much nitrogen may result in lush foliage and a shortage of blooms.
Plant Hellebore seeds in the fall. A 60-day moist chilling period is needed when planting seeds of the Hellebore plant. Planting seed in fall allows this to happen naturally in areas with cold winters. Wait three to four years for blooms on young plants grown from seed. Divide overgrown clumps in spring, after flowering or in autumn.

Greater Celandine (Chelidonium majus) is alovely shade loving perennial plant that is ideal for woodland settings. Will naturalize in woodlands and bring them to life in late spring with a mass of bright yellow flowers floating in blue-green foliage.
Once established these plants take little or no maintenance. It is a short lived perennial hardy to zone 6 but it will self seed in suitable surroundings and may take over an area if not watched. It likes a good moist soil, which is most often found in woodlands, but it will also grow on semi shaded walls and rock gardens. Ideal for rocky wooded locations. Due to the alkaloid content this plant is not eaten by deer or rabbits. All parts of the plant will exude a yellow/orange sap when broken. This can cause skin problems in some people. The plant is considered to be mildly poisonous.
It is reported that the leaves can be eaten if boiled well and water changed several times. Greater Celandine has a long history of use in herbal medicine. The leaves and the sap are used most often as a mild sedative detoxifying and antispasmodic especially for relaxing the bronchial tubes, intestines and muscles as well as whooping cough, asthma, jaundice, gallstones and gallbladder pains. Caution should be taken when using this herb internally since it contains the many alkaloids that are considered toxic. The orange sap is used externally to treat warts, ringworm and corns as well as films from the cornea of the eye. The roots are also used and research has shown them to have possible anticancer properties.
Growing Conditions and General Care Greater Celandine will grow in almost any soil except waterlogged but it does like a reasonable amount of water. Ideal plant for part or full shade but it will grow in full sun in lower zones (6 and 7) provided it has moisture. Prefers a rich woodland soil in semi shade with decent moisture. It is an excellent choice for growing on partially shaded walls or in rock gardens provided there is a pocket of soil to establish its roots. It is a short lived perennial but it will self seed in suitable locations, sometimes aggressively and will take over thin woodland areas if left alone.
Growing from Seed Germination can be slow and erratic with some seeds taking up to twelve months to sprout. Can be sown in place in early spring or late fall. If choosing this approach keep weeds in the area to a minimum to allow seeds time to germinate and plants to establish. Once the first ones are established they often self seed and proliferate, but this can take several years to achieve. Seeds and also be started in pots. Individual pots with several seeds per pot or cell flats are recommended so seedlings can be removed as they grow without disturbing other seeds. Some will often germinate rapidly but others may not so patience is needed. Start indoors in later winter and remove plants as they become large enough to transplant. Place rest of growing medium outside in a semi shaded area and continue to water throughout the year picking out seedlings as they appear. It is best if they pots/flat are placed on a bench or shelf to reduce weed seed introduction to the growing medium. Trays can be left out over winter if all the seeds have still not germinated.
Harvesting Greater Celandine plants are harvested during the spring when they begin to bloom. Herb can be used fresh or dried for later use. Roots are harvested in the fall when they are at their peak. These can also be dried for later use. It is highly recommended that gloves be worn when harvesting any of this plant from leaves, roots or seeds. The latex is mildly toxic and many people have a allergic reaction that can cause rashes and skin.

Laburnums are more commonly known as Golden Chain Trees. In the spring, the tree blooms with large clusters of bright yellow flowers. The panicles, or clusters, can be up to 10 inches (25 cm) in length.
Desirable for their showy spring appearance, the trees can grow on a single trunk or as a shrub. Although attractive and relatively free of pests, they can be moderately difficult to grow, as the plants have rather specific environmental needs. Laburnums thrive best in U.S. Department of Agriculture plant hardiness zones 6 through 8.
Growing Conditions and General Care Choose a growing site that is exposed to full sunlight. The more sunlight, the better the Laburnum will bloom. An exception to this rule is home gardeners who live in USDA zone 8. Laburnums do not tolerate heat well, so gardeners who live in hotter climates should choose a location that gets morning sun but is shaded from direct exposure to hot afternoon sunlight. Plant your Laburnum in rich, well-drained soil. These trees are small — they average about 20 feet (50 cm) in height — so they can also be grown in containers. If you use a container, make sure it has drainage holes.
Water frequently. These trees thrive in cool, moist soils and grow best in climates that have mild, wet summers. Water at least once each week — more often when the weather is hotter than usual. Fertilize in early spring, before bud break. Use a fertilizer formulated for flowering trees and shrubs, and one that has a high acid content. Laburnum thrive in high pH soils. Follow the directions on the package according to the size and age of your Laburnum. Wrap the trunk of the tree with tree wrap — available at any local garden center — to protect the bark from being damaged by the sun in the winter. This damage is called “sunscald,” and it happens when a warm winter day is followed by freezing temperatures. Wrap the tree in the fall, before colder weather arrives.
Tip Home gardeners who live in USDA zone 8 might be wise to grow their plants in containers. This way, they will get the full effect of the sun during most of the spring, and blooming will be optimized. When midsummer arrives, the tree can be moved to the shade.
Warning The flowers and seed pods of this tree are poisonous, so keep them out of reach of children and pets.

The Meconopsis genus contains short lived hardy perennials that reach a height of 1 to 5 feet (30 cm to 1.5 m). They carry poppy like flowers that can bloom in spring, summer or the start of autumn (species dependent). Many Meconopsis species are known for their blue poppy like flowers but they can also carry flowers of many other colors including white, orange, pink and yellow. Some of the common names for Meconopsis include Welsh Poppy, Asiatic Poppy, Blue Poppy and Harebell Poppy.
The Blue Poppy is the national flower of Bhutan. Welsh poppies can be invasive. Growing Conditions and General Care Full sunlight (cool areas only); full or partial shade. Acidic soil. Add grit to heavy soils. Nutrient-rich soil, add manure, leaf matter or compost if necessary. Moist soil. Supply mulch of manure of bark chippings when planting to help maintain moisture; do not cover the crowns. Regular watering during dry periods in summer to keep the soil moist. No need to water in the winter as the plant prefers a dry soil whilst resting. Cut back to the ground in autumn. Replace regularly as Meconopsis do not live for long time.
How to Grow from Seeds The seeds of the Meconopsis should be sown on the surface; this can wither be done just before the last frost of spring or towards the end of autumn. Blue Poppies prefer to grow in a shady or partially shady part of the gardens but can tolerate sunny areas in milder climates. They like a rich acidic soil, ideally the soil should be kept moist in the summer, but allowed to dry in the winter. When starting Blue Poppy off indoors do so about two months in advance. The Meconopsis seeds should be sown in vermiculite. It should take about two to four weeks for blue poppy to germinate at 54 to 64 degrees Fahrenheit (12 to 18 degrees Celsius). Once growing the seedlings should be watered from beneath. Once ready transplant the young Meconopsis plants at a spacing of 12 inches/30 cm (small) to 2.5-3 feet/75-90 cm (large) apart. This should be done following the last frost of spring.
Grower’s Tips When growing Meconopsis plants in the garden it is very important to keep the soil moist in the summer. Once the growing period has finished, cut back Meconopsis plant to ground level (autumn). If you require more plants then they can be propagated by division at the start of spring.

Mountain Laurel (Kalmia latifolia) is a broad leaf evergreen that grows and flowers well in full sun to part shade, making it a versatile shrub in the landscape. The broad, dark green leaves provide interest all year long. In spring clusters of cup-shaped flowers open in shade of white, pink and red. It’s a favorite of bees and butterflies.
The shrub grows naturally in the filtered light under tall deciduous trees such as oak and maple, especially near a wet, swampy area. It flowers best, though, with more sun in an open landscape, but the leaves may turn a yellow-green color in full sun.
Growing Conditions and General Care Mountain Laurel is hardy to zone 5. In colder areas it will need to be protected in winter with burlap barriers to block the winter wind. Purchase plants from your local garden center. Look for the hardiest varieties for cold areas. Plant shrubs from spring, after all danger of frost has passed, to summer in well drained, moist, acidic, cool soils. Avoid windy areas, if possible. Space plants 4 to 6 feet (1.2 to 1.8 m) apart.
Propagation Start seeds indoors in spring at 43 to 54 °F (6 to 12 °C). Take greenwood cuttings in late spring or semi-ripe cuttings in mid-summer. Layer in late summer. Grower’s Tips Keep young shrubs well watered. Keep the soil evenly moist and acidic with a layer of wood chips or evergreen bark mulch. Fertilize mountain laurel in spring with a plant food for acidic-loving plants such as you’d use for Rhododendrons.
Mountain Laurel will get spindly, develop leaf spots and have few flowers if grown in too much shade. Look for leaf spot resistant varieties if growing under these conditions. It also doesn’t grow well in poorly drained soils. It’s a slow grower that should only be pruned to shape the plant in spring after flowering. Dead, diseased and broken branches can be taken out at any time. Mountain laurel doesn’t have many pest problems.

Nigella sativa, also called Black Cumin, is an annual flowering plant discovered in ancient Egypt. The plant develops an attractive flower that makes a delicate accent bloom for fresh and dried arrangements.
Allowing the bloom to fade and turn into a pod produces an edible seed used as a flavoring in foods. Plant Nigella sativa seeds when no risk of frost exists. Sprouts appear in one to two weeks and flowers in about two to three months later. Growing Conditions and General Care Test the soil pH with a home kit two to three months before the desired planting date to verify the pH is slightly acidic with a value of 6.0 to 7.0. Work ground rock sulfur into the soil to lower the pH if needed. Follow the package application rate based on the current pH. Let the soil rest for two to three months to give the amendment time to change the pH.
Work 2 to 3 inches (5 to 7.5 cm) of organic compost into the planting area to a depth of 8 to 10 inches (20 to 25 cm). Compost increases the nutrient value of the soil and is a natural fertilizer. Sprinkle the Nigella sativa seeds lightly over the planting area. Sprinkle about 1/4 to 1/2 inch (8 to 13 mm) of soil over the seeds. Pat the soil gently to hold the seeds in place. Sprinkle the planting area gently with water to moisten the soil to a depth of 1 to 2 inches (2.5 to 5 cm). Use caution to prevent heavy streams of water that will cause seed run-off. Keep the soil evenly moist, but not wet, to stimulate germination and plant growth. Thin out plants once the seedlings reach 2 to 3 inches (5 to 7.5 cm) tall. Pinch off weak sprouts that are growing too close together. Attempt to space the plants 4 to 6 inches (10 to 15 cm) apart. Always keep the healthiest sprouts.
Deadhead the plants by clipping off the flowers when they begin to fade. Leave the flowers on the plant if you want them to turn into seed pods. Grower’s Tips Work horticulture limestone into the soil to raise the pH if it is below 6.0. Follow the package instructions based on the current pH.
Apply a flowering plant fertilizer once the plants are 4 to 6 inches tall if you don’t amend the soil with organic compost.

Solidago, commonly called Goldenrod, is a genus of about 120 species of flowering plants in the Aster Family, Asteraceae. Topped with plumes of fluffy yellow flowers, Goldenrod is sometimes considered a weed.
Unknowing gardeners may find it a nuisance and wonder, “What is the plant Goldenrod good for?” Goldenrod plants have multiple uses, from providing shelter to larvae of beneficial insects to attracting butterflies. Learn how to grow goldenrod and experience the many benefits.
After learning the many benefits of planting Goldenrod and the simplicity of Goldenrod care, you may wish to include it near your garden. Goldenrod plants provide nectar for migrating butterflies and bees, encouraging them to remain in the area and pollinate your crops. Planting Goldenrod near the vegetable garden can draw bad bugs away from valuable vegetables. Goldenrods attract beneficial insects as well, which may do away with damaging insects when they approach the food source offered by these plants. More than a hundred varieties of Goldenrod exist, with one for every climate. Many are native to the United States.
Goldenrod plants are clump-forming perennial wildflowers that exist on rainwater and add a golden beauty to the landscape. Often thought of as the cause of summer allergies, the species is falsely accused, as the pollen from allergy-creating ragweed is present at the time of Goldenrod blooms. All Goldenrods are late bloomers, flowering in late summer throughout fall with stunning bright yellow flowers. Growing Conditions and General Care Growing and planting Goldenrod is easy, as this plant will survive just about anywhere, though it does prefer to be grown in full sun. Goldenrod also tolerates various soil types as long as it’s well draining.
Goldenrod care is minimal once established in the landscape, with plants returning each year. They require little, if any watering, and are drought tolerant. Clumps need division every four to five years. Cuttings may also be taken in spring and planted in the garden.
Learning how to grow Goldenrod offers many advantages. Bad bugs can be drawn to the plant and consumed by beneficial insects that hatch their young there. Planting Goldenrod adds beauty and attracts butterflies to your landscape.

Chicory (Cichorium intybus) is an herbaceous biennial that is not native to the United States but has made itself at home. The plant can be found growing wild in many areas of the U.S. and is used both for its leaves and its roots. Chicory herb plants are easy to grow in the garden as a cool season crop. Seeds and transplants are the primary means of growing Chicory.
There are two types of Chicory plant. Whitloof is grown for the large root, which is used to make a coffee supplement. It can also be forced to use the tender white leaves called Belgian Endive. Radicchio is grown for the leaves, which may be in a tight head or a loosely packed bunch. Radicchio is best harvested very young before it turns bitter.
Growing Conditions and General Care Seeds can be started indoors five to six weeks before they are moved outdoors. In warm climates, sowing outdoors or transplanting occurs September through March. Planting Chicory in cooler climates should be done three to four weeks before the danger of frost has passed. Sow Chicory seeds 6 to 10 inches (15 to 25 cm) apart in rows that are 2 to 3 feet (60 to 0) apart. You can always thin the plants if they crowd each other but close planting discourages weeds. The seeds are planted ¼ inch (6 mm) deep and thinning is done when the plants have three to four true leaves. You can also sow a crop for fall harvest if you choose a variety that has an early maturation date. Planting Chicory seed 75 to 85 days before anticipated harvest will ensure a late crop.
Chicory plants that are to be forced for blanched leaves will need to have the roots dug up before the first frost. Cut the leaves to 1 inch (2.5 cm) and store the roots for three to seven weeks in the refrigerator before forcing. Plant the roots individually after chilling to force the leaves to grow in a tight, blanched head. Learning how to grow Chicory is similar to learning how to grow most lettuces or greens. The cultivation is very similar. It requires well drained soil with plenty of organic matter. It performs best when temperatures are below 75 °F (24 °C).
Extended care of the Chicory crop requires vigilant weeding and a mulch to prevent moisture loss and further weed growth. It requires 1 to 2 inches (2.5 to 5 cm) of water per week or enough to keep the soil evenly moist and reduce the chance of drought stress. Chicory is fertilized with ¼-cup of nitrogen based fertilizer such as a 21-0-0 per 10 feet (3 m) of row. This is applied approximately 4 weeks after transplant or once the plants have been thinned.
Growing Chicory as a forced vegetable necessitates row covers or individual plantings that are kept from light.

What southern garden is complete without the majestic, fragrant Magnolia tree? If you’ve long admired the beauty of Magnolias, you’ll be happy to learn that they’re quite easy to grow. And with over 80 species native to North America and Asia, there’s sure to be one that’s right for your yard.
With their glorious flowers and dramatic foliage, magnolias are a garden favorite. Magnolias: – Require very little care. – Are resistant to many diseases and pests. – Tolerate harsh Southern summers. – Provide year-round beauty. – Seeds and foliage are favorites of migrating birds. As you dream about Magnolias in your yard, keep in mind that there are many different species and varieties to choose from. They range in size from 20 to 80 feet (6 to 24 m) tall, with both evergreen and deciduous species.
Growing Conditions Although different species of Magnolia can tolerate slightly different conditions, in general they will do best with: Soil: Slightly acidic, moist, loose, well-draining soil. To mimic Magnolia’s natural conditions, amend heavy soil with peat moss and compost. Hardiness: Grow best in Zones 7-10, depending on variety, with a few cultivars hardy to zone 5. Light: Full sun to partial shade. Moist, peaty soil can help Magnolias tolerate full sun. If you’re pushing the limits of cold tolerance, avoid planting Magnolias in southern exposure since the leaves can be damaged by winter sun and flowers may open prematurely. Water: Magnolias benefit from irrigation the first few years, then they are tolerant of moderate drought. Space: They need room to grow to their full mature size and width. While looking small when first planted, over time they’ll grow to fill up the space.
Flowers: Some varieties of Magnolia don’t bloom until 15 years old, so be sure to choose one that’s fits your needs and expectations. Grafted plants (rather than seed-grown) bloom sooner. Planting Tips Timing: Plant container-grown and balled-and-burlapped Magnolias in fall or spring. Plant field-grown or transplanted Magnolias in early spring. Avoid fall planting if you’re pushing the limits of cold tolerance. Spread Roots: When planting, be sure to cut any roots that are circling the root ball. Magnolias have a tendency to girdle (or become rootbound) if the roots aren’t spread out.
Water: Give your new Magnolia one inch of water per week. Fertilizer: Don’t fertilize your newly planted Magnolia until next growing season. Then for the next three years or so, feed your Magnolia with a balanced organic fertilizer every other month between March and September, cutting back to once or twice per season after that. Support: Use stakes and lines to stabilize your new magnolia since it will be top-heavy.
Growing Tips Problems: Magnolias are generally trouble-free, and in most cases, minor problems – such as scale or leaf spots – can be left untreated. Pruning: If you want to prune or shape your Magnolia, do it while the tree is very young since large branches don’t heal very well from pruning. Bark Damage: Magnolias are susceptible to bark damage and breakage, so avoid hitting them with the string trimmer or lawn mower. Propagating: You can propagate Magnolias by collecting the seeds, or take semi-hardwood cuttings in late summer. Cuttings can take up to a year to root.
Transplanting: Magnolias have an enormous, rope-like root system. They don’t usually tolerate transplanting once the trunk is 4 inches (10 cm) or larger in diameter.

The genus Ferraria was named in honor of Giovanni Battista Ferrari, who first described a Ferraria in 1633. Ferrarias were brought to Europe before the middle of the 17th century and cultivated there as items of interest, in part due to their unusual flowers.
Growing in spring from underground corms, Ferrarias are primarily grown for their unique and frilly, speckled flowers, which usually range in shades of brown to yellow, violet and blue or combinations of all of these colors and even green. Ferrarias last a single day, but established plants will usually produce a large number.
Ferrarias also have an unusual shape. They are relatively small and many of the flowers emit an unpleasant aroma, reminiscent of rotten meat. However, there are some spider flowers that are sweetly scented such as F. brevifolia, F. kamiesbergensis and F. schaeferi. Ferrarias make lovely additions to the garden, adding a unique charm of their own. The star-like flowers, which resemble a starfish, have also prompted the nickname of Starfish Lily.
Growing Conditions and General Care Ferrarias are easy bulbs to grow. These plants prefer to be located in sun or semi-shade in loamy, well-drained soil just beneath the surface (1-2 inches/2.5-5 cm). Plants in too much shade will fail to bloom and will eventually die out. The rarer species are generally best grown in pots or containers. The care of Ferraria corms don’t require too much either. Once their spring flowering has completed, the foliage will slowly begin to fade and the Ferraria flowers go dormant in summer. During this time, all watering should be limited.
Bring any container-grown plants indoors for over wintering and provide a generous amount of mulch for winter protection to those growing outdoors. Established Ferraria plants will produce large clumps each year. These can be easily divided in the spring when overcrowding becomes a problem or if additional plants are desired elsewhere in the garden.
