Scientific Name
Rudbeckia hirta L.
Common Names
Black Eyed Susan, Brown Eyed Susan, Brown Betty, Gloriosa Daisy, Golden Jerusalem, Poorland Daisy, Yellow Daisy
Synonyms
Rudbeckia hirta var. hirta, Rudbeckia hirta f. hirta, Centrocarpha gracilis, Centrocarpha hirta, Coreopsis hirta
Scientific Classification
Family: Asteraceae
Genus: Rudbeckia
Flower
Color: Yellow
Bloom Time: Late summer and early autumn
Description
Rudbeckia hirta is an upright annual (sometimes biennial or perennial), up to 39 inches (1 m) tall and up to 18 inches (45 cm) wide. The leaves are alternate, mostly basal, up to 7 inches (17.5 cm) long, covered by coarse hair, with stout branching stems and daisy-like, composite flowers appearing in late summer and early autumn. The flowers are up to 4 inches (10 cm) in diameter, with yellow ray-florets circling conspicuous brown or black, dome-shaped disc-florets.
How to Grow and Care
Black Eyed Susan plants are drought resistant, self-seeding and grow in a variety of soils. Growing Black Eyed Susans prefer a neutral soil pH and a full sun to light shade location.
Black Eyed Susan care will often include deadheading the spent blooms of the flower. Deadheading encourages more blooms and a sturdier, more compact plant. It also can stop or slow the spread of the Black Eyed Susan flower, as seeds are contained in the blooms. Seeds may be allowed to dry on the stem for reseeding or collected and dried in other ways for replanting in other areas. Seeds do not necessarily grow to the same height as the parent from which they were collected.
The Black Eyed Susan flower attracts butterflies, bees and other pollinators to the garden. Deer, rabbits and other wildlife may be drawn to Black Eyed Susans, which they consume or use for shelter. When planted in the garden, plant the Black Eyed Susan flower near Lavender, Rosemary or other repellent plants to keep wildlife at bay.
Origin
Native to the Eastern and Central United States.

Scientific Name
Aster tataricus L.f.
Common Names
Tatarian Aster, Tartarian Aster, Tatarian Daisy, Tatarinow’s Aster
Synonyms
Aster fauriei, Aster nakaii, Aster rhomboideus, Aster tataricus var. tataricus
Scientific Classification
Family: Asteraceae
Tribe: Astereae
Genus: Aster
Flower
Color: Deep lavender to blue rays and yellow centers
Bloom Time: Autumn
Description
Aster tataricus is an impressive, stately perennial with a flowering height of up to 6 feet (1.8 m). Distinctive paddle-shaped, lower leaves are up to 24 inches (60 cm) long and up to 6 inches (15 cm) wide, but leaves are significantly smaller in size higher up on the plant. Small but abundant flowers, up to 1 inch (2.5 cm) across, with deep lavender to blue rays and yellow centers appear in flat-topped clusters in autumn. A late blooming aster that still looks fresh at time of first frost.
How to Grow and Care
Divide mature plants in spring, just as the new shoots begin to grow. This should be done every few years to avoid crowding of plants.
As with many other flowering plants, dead head (cut back spent flowers) to make room for newer blossoms. This will extend the health and flowering of your plants. Be sure to dead head early on in the blooming season. Blooming will be reduced if done too late. This will also restrain unwanted reseeding which will cause plant overcrowding.
Remember, Asters are prone to mildew so be careful to plant them in areas with good circulation and good sun exposure.
As with other flowering plants, do not allow water to saturate leaves. Be sure to water at the plant’s roots to prevent mildew and mold. Drip irrigation and utilization of a soaker hose work very well in watering these plants.
Origin
Native to southern Siberia, northern China, Mongolia, Korea and Japan, where it grows in meadows and wetlands.

Carpobrotus, commonly known as Pigface, Ice Plant, and Hottentot Plant, is a genus of ground-creeping plants with succulent leaves and large daisy-like flowers. The name refers to the edible fruits. It comes from the Ancient Greek karpos (“fruit”) and brota (“edible”).
The genus includes about 20 accepted species. Most are South African, endemics, but there are at least four Australian species and one South American.
Various Carpobrotus species are invasive introduced species in suitable climates throughout the world. The harm they do is variable, and sometimes hotly debated, when balanced against their value as firebreaks and as food for wildlife.
Growing Conditions
Carpobrotus is a perennial plant in its chosen zones but also thrives as an annual in colder areas. The best temperature range for the succulent is between 40 and 100 ˚F (4 – 14 ˚C), but some protection from the sun’s scorching rays may be required in the higher temperature ranges.
Growing Carpobrotus in planters prevents it from spreading in those areas where that is a concern. Freezing temperatures may cause the plant to die back, but it will resprout in spring in temperate area.
Propagation
Stem cutting is the fastest way to propagate this fast growing plants. Seeds are also available and you may start them indoors at least six weeks before the date of the last frost.
General Care
Ice plants are notoriously un-fussy. As long as their soil drains well, the soil is allowed to dry out between watering and the plant receives pinching or pruning to keep it in shape, there is little more to be done.
The only serious threats to the plant’s health are spittle bugs and some root rots and stem rots. You can avoid the rot by minimizing overhead watering during periods in which the plant will not dry off before nightfall. The bugs will remove themselves if you spray with a horticultural soap.
Growing Carpobrotus in containers is ideal, and you can overwinter them in temperate regions. Just bring the pot in and water it deeply. Cut back the plant and let it dry out and languish for the winter in a warm location. In March, resume regular watering and move the plant to a full light situation where it has some protection from burning rays. Gradually reintroduce the plant to temperatures outdoors until it can tolerate a full day outside.

Frithia are low-growing evergreen succulent perennials with erect, club-shaped leaves with a clear window at the apex, and solitary, daisy-like red to purple flowers in late winter.
The genus Frithia was established by N.E. Brown (1925), a taxonomist based at Kew Herbarium. At that stage no species were assigned to this genus and only later was a full description of Frithia pulchra given (Brown 1926). It was named after Frank Frith (1872 – 1954), a railway services gardener stationed at Park Station, Johannesburg, who took the specimens to Brown at Kew while on a visit to London. Brown named Frithia in honour of the man who brought him the specimens. The specific epithet “pulchra” is derived from the Latin “pulcher” meaning beautiful.
Growing Conditions
Light: The plant will take as much light as you can give it, but fierce sunshine could “scorch” the plant. In habitat the plant overcomes this problem by only having the leaf tips showing above the ground.
Soil: An open compost is essential and if the only pot available is a deep one fill the bottom half with coarse grit or gravel.
Water: Frithia is not shy of water and should be watered regularly during the growing season, but the water must be able to drain away quickly. Keep the plant dry in winter.
Fertilizer: When in growth feed every two or three weeks with a low nitrogen liquid fertilizer.
General Care
Frithia is a summer grower and relatively easy to cultivate. It need light sporadic watering during its winter resting period and requires moderate sprinkling in summer as it is rot prone if kept too moist when the heat turns off its growth cycle. Gritty, well drained soil, containing a small amount of organic material will keep this species happy. Frithia can be grown in pots or out of doors in a rockery. Soak the compost fully but allow it to dry out perfectly between waterings. Under-watering can lead to disastrous results, so be generous with water in summer. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid. Keep dry in the winter. It does well in full blazing sun, as well as whit some shade in summer.
Propagation
Frithias can be sown from seed sown in a gritty sandstone medium or propagated vegetatively by division.

A member of the sunflower family, arnica (Arnica spp.) is a perennial herb that produces yellow-orange, daisy-like blooms in late spring and early summer. Also known as mountain tobacco, leopard’s bane and wolfbane, arnica is highly valued for its herbal qualities. However, before you decide to grow arnica or use the herb medicinally, there are a number of things you should know. 
Arnica Herb Uses
What is arnica herb for? Arnica has been used medicinally for hundreds of years. Today, the roots and flowers are used in topical treatments such salves, liniments, ointments, tinctures and creams that soothe tired muscles, relieve bruises and sprains, ease the itch of insect bites, soothe burns and minor wounds, promote hair growth and reduce inflammation. Although the herb is usually applied topically, homeopathic remedies with highly diluted amounts of the herb are available in pill form. Arnica is generally safe when used topically, although products containing arnica should never be used on broken skin. However, arnica should never be taken internally except when the doses are small and extremely diluted (and with the guidance of a professional). The plant contains a number of toxins that can cause a variety of potentially dangerous results, including dizziness, vomiting, internal bleeding and heart irregularities. Ingesting large amounts can be deadly.
Arnica Growing Conditions
Arnica is a hardy plant suitable for growing in USDA plant hardiness zones 4 through 9. The plant tolerates nearly any well-drained soil, but generally prefers sandy, slightly alkaline soil. Full sunlight is best, although the arnica benefits from a bit of afternoon shade in hot climates.
How to Grow Arnica
Planting arnica isn’t difficult. Just sprinkle the seeds lightly on prepared soil in late summer, then cover them lightly with sand or fine soil. Keep the soil slightly moist until the seeds germinate. Be patient; seeds usually sprout in about a month, but germination can take much longer. Thin the seedlings to allow about 12 inches between each plant. You can also start arnica seeds indoors. Plant the seeds in pots and keep them in bright, indirect sunlight where temperatures are maintained at approximately 55 F. (13 C.) For best results, grow the plants indoors for several months before moving them to a permanent outdoor location after all danger has passed in spring. If you have access to established plants, you can propagate arnica by cuttings or divisions in spring.
Arnica Plant Care
Established arnica plants require very little attention. The primary consideration is regular irrigation, as arnica is not a drought-tolerant plant. Water often enough to keep the soil lightly moist; don’t allow the soil to become bone dry or soggy. As a general rule, water when the top of the soil feels slightly dry. Remove wilted flowers to encourage continued blooming throughout the season. Disclaimer: The contents of this article is for educational and gardening purposes only. Before using ANY herb or plant for medicinal purposes, please consult a physician or a medical herbalist for advice.

This prickly wildflower is not in fact a member of the dock family; it belongs to the daisy family, Asteraceae. Burdocks bloom from July until September, and they are generally found in shady places or on waste ground. Typically, the plant grows to a metre, with flower heads between 15 mm and 30 mm in diameter. The seed heads, or burs, have hooked bracts and become attached to the fur of animals; in this way the seeds are distributed.
Another burdock that you will find in Wales and throughout the UK is the Greater Burdock, Arctium lappa. It is very similar to lesser burdock, but has rounder leaves and rounder, somewhat larger flowers: the flowers of greater burdock can be up to 40 mm in diameter.

Identification
Unlike other daisy-like flowers, plants of the genus Andryala have large 'petals' on all florets and not just those on the periphery flower head. The plant is extremely hairy and has barrel-shaped buds surrounded with a neatly-arranged single row of hairy bracts.
Growing to between 30 and 75cm in height with branching stems covered in dense, soft white down that gives an overall whitish appearance to the plant, Andryala integrifolia has alternate lanceolate hairy leaves that are often corrugated (with wrinkled wavy margins).
The flowers are hermaphrodite (posessing both male and female reproductive organs), and they are a delicate lemon yellow. Flowers are grouped into corymbs (loose clusters) of typically three to nine composite heads, each head being in the range 1.5 to 8cm across, but most commonly between 2.5 and 5cm across.
Distribution
This wildflower is seen throughout the Mediterranean region. Well known in the Iberian Peninsula, where it is both widespread and common, Andryala integrifolia can be found from north Africa as far east as Greece, Sicily and Italy.
Habitat
This lovely wildflower tends to frequent rather sandy or rocky ground, but it can also be found on heaths, in abandoned farmland, and on some stony roadside verges.
Blooming Times
In the Mediterranean region where it is native, Andryala blooms from April to July.
Uses
A toxic latex within this plant contains hydrogen cyanide, and so no parts of Andryala should ever be eaten.

Yarrow produces flat-topped inflorescences, and as a result it is sometimesmistaken for one of the umbellifers (Apiaceae). In fact Yarrow is a member of the daisy family, Asteraceae.
Identification
The plants have feathery leaves arranged around the stems, which can grow up to a metre but are usually less than 0.5m tall, and an inflorescence comprises three to eight roundish ray flowers surrounding between 15 and 40 tiny disc flowers.
Distribution
Yarrow is very common throughout Britain and Ireland, and it occurs also across Europe and Asia as well as in North America.
Habitat
This wayside wildflower is found mainly on drier slopes and meadows as well as on many grassy roadside verges.
Blooming Times
Achillea ptarmica blooms in Britain and Ireland from June until October, and is generally at its best in July and August.
Reproduction
Yarrow can reproduce either by means of seeds or by vegetative means. The oblong to lance-shaped fruits of Yarrow are about 2mm long, flattened, and ribbed longitudinally.
Each fruit of Yarrow, known as an achene, contains a single seed, but reproduction is also achieved vegetatively by means of underground creeping stems known as rhizomes, from which new plants (which are therefore clones of the parent plant) arise.
Uses
Considered a plant of the devil in Wales, this wildflower has long been thought to bring bad luck (or even death) if its flowers are brought in to a home. Yarrow is, in any case,
There are many traditional medical uses recorded for this plant, including its use as an astringent to cure bleeding noses.
Herbal tea can be made from the flowers, although given its known medical properties this practice seems rather inadvisable.
Etymology
The generic botanical name Achillea stems from the belief that Achilles used Yarrow to treat the wounds of his soldiers. The finely divided leaves give it its specificname (millefoilium means 'with 1000 leaflets').
Varieties
Most Yarrow flowers are white or cream, but some have a mauve flush or occasionally a purple tinge. Other colour forms seen in the wild are almost certainly the result of garden escapes.
In Scandinavia a red-flowered form of Yarrow is found occasionally in the wild. It is not a separate species nor even a subspecies but rather merely a hereditary colour variant; however, selective breeding in cultivation has enabled nurseries to produce Yarrow cultivars raging through white, cream and yellow to mauve, purple, pink and red.
Similar Species
Sneezewort, Achillea ptarmica, has larger flowers and fewer of them; it grows in damp grassland sites.
Identification
The plants have feathery leaves arranged around the stems, which can grow up to a metre but are usually less than 0.5m tall, and an inflorescence comprises three to eight roundish ray flowers surrounding between 15 and 40 tiny disc flowers.
Distribution
Yarrow is very common throughout Britain and Ireland, and it occurs also across Europe and Asia as well as in North America.
Habitat
This wayside wildflower is found mainly on drier slopes and meadows as well as on many grassy roadside verges.
Blooming Times
Achillea ptarmica blooms in Britain and Ireland from June until October, and is generally at its best in July and August.

BOTANICAL NAME: Leucanthemum x superbum
PLANT TYPE: Flower
SUN EXPOSURE: Full Sun
SOIL TYPE: Any
FLOWER COLOR: White
BLOOM TIME: SummerFall
SPECIAL FEATURES: Attracts Butterflies
The cheerful shasta daisy is a classic perennial. It looks similar to the familiar roadside daisy but has larger and more robust blooms. Here’s how to grow shasta daisies in your garden!
Shasta daisies tend to bloom in clumps from 2 to 3 feet tall and 1 to 2 feet wide. They bear all-white daisy petals, yellow disk florets, and contrasting glossy, dark green leaves.
Like clockwork, shasta daisies return every spring or early summer and bloom until early fall. They are never invasive (like some consider roadside daisies to be) and they are terrific for cutting.
PLANTING
Grow in full sun.
Soil should be moderately fertile, not overly rich, and moist but well-drained.
Sow seeds in containers in a cold frame in autumn or spring. Divide perennials in early spring or late summer.
If you seed directly, expect blooms the following spring after one season’s growth.
If purchasing a plant in a container, plant in spring.
Loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost.
Space plants 1 to 2 feet apart. Dig a hole twice the diameter of the container.
When placing plant in the hole, make sure the top of the root ball is level with the soil surface.
Fill around the root ball and firm the soil.
Water thoroughly.
Many of the taller plants need support/staking.
CARE
Water during the summer only if rainfall is less than 1 inch per week.
After the first killing frost, cut stems back to an inch or two above the soil line. (See local frost dates.)
Every spring, apply some compost and mulch to help control weeds.
Every 3 to 4 years, divide perennials again in early spring or late summer.
PESTS/DISEASES
Aphids, slugs, earwigs, chrysanthemum nematode, and leaf spots may be troublesome. However, daisies are generally low maintenance.

BOTANICAL NAME: Aster
PLANT TYPE: Flower
SUN EXPOSURE: Full SunPart Sun
SOIL TYPE: Loamy
SOIL PH: Varies
FLOWER COLOR: PinkPurpleRedWhite
BLOOM TIME: SummerFall
SPECIAL FEATURES: Attracts Butterflies
Asters are daisy-like perennials with starry-shaped flower heads. They bring delightful color to the garden in late summer and autumn when many of your other summer blooms may be fading.
The plant’s height ranges from 8 inches to 8 feet, depending on the type. You can find an aster for almost any garden and they have many uses, such as in borders, rock gardens, or wildflower gardens. Asters also attract butterflies to your garden!
PLANTING
Asters prefer climates with cool, moist summers—especially cool night temperatures.
Select a site with full sun to partial sun.
Soil should be moist, well-drained, and average to humus-rich.
Plant asters in early to mid-spring. Fertilize soil prior to planting. (Learn more about soil amendments and preparing soil for planting.)
While the plant can be grown from seed, germination can be uneven. You can start the seeds indoors during the winter by sowing seeds in pots or flats and keeping them in the refrigerator for 4 to 6 weeks. After 4 to 6 weeks, put the seeds in a sunny spot.
Set seeds one inch deep.
Many gardeners opt for purchasing a potted plant from the nursery instead.
Space asters 1 to 3 feet apart, depending on the type.
Give plants plenty of water at planting. Add mulch after planting to keep soil cool and prevent weeds. If you’re replanting shoots, use vigorous, young shoots to ensure best growth.
CARE
Add a thin layer of compost with a 2–inch layer of mulch around the plants every spring.
If you receive less than 1 inch of rain a week, remember to water your plants regularly during the summer. However, many asters are moisture-sensitive; if your plants have too much moisture or too little moisture, they will often lose their lower foliage or not flower well. Keep an eye out for any stressed plants and try a different watering method if your plants are losing flowers.
Stake the tall varieties in order to keep them upright and remember to pinch the young shoots to encourage bushiness.
Cut asters back in winter after the foliage has died.
Divide every 2 to 3 years in the spring to maintain your plant’s vigor and flower quality.
