Scientific Name Aeonium arboreum (L.) Webb & Berthel
Common Names Thickleaf Aeonium, Pinwheel Desert Rose, Fisiulera, Tree Aeonium, Tree Anemone, Houseleek Tree, Irish Rose Synonyms Sempervivum arboreum, Aeonium korneliuslemsii Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Aeonium
Flower Color: Yellow Bloom Time: Mid spring to early summer Description Aeonium arboreum is a medium-green succulent which forms branched stems, up to 3 feet (90 cm) tall, looking like a miniature tree. Rosettes are formed at the ends of the stems. They grow quickly and produce abundant yellow flowers form long clusters in mid spring to early summer.
How to Grow and Care Aeoniums do not like really hot or dry weather. They may go dormant in summer and do not require any water, except in very dry conditions. In extreme heat, their leaves will curl, to prevent excessive water loss. Growing them in moist shade will keep them growing, but their true growth season is winter to spring, when temperatures are cool (65–75˚F / 18–24˚C) and damp. In the winter, water whenever the soil has dried out. Test by poking your finger down into the soil an inch or two. Too much moisture or allowing them to sit in wet soil will cause root rot… – See more at: How to Grow and Care for Aeonium. Propagate Aeoniums by stem cuttings, except for unbranched species which die after flowering and are propagated from seed. Take cuttings when the plant is actively growing, usually fall in USDA zones 9 through 11. Aeoniums go dormant in summer; cuttings taken while plants are dormant don’t root. Each leaf rosette dies after it blooms. Origin Native to North Africa and Canary Islands.

Scientific Name Achillea millefolium L. Common Names Yarrow, Common Yarrow, Milfoil, Gordaldo, Nosebleed Plant, Old Man’s Pepper, Devil’s Nettle, Sanguinary, Soldier’s Woundwort, Thousand-Leaf, Thousand-Seal Synonyms Achillea borealis, Achillea lanulosa, Achillea magna Scientific Classification Family: Asteraceae Subfamily: Asteroideae Tribe: Anthemideae Subtribe: Matricariinae Genus: Achillea Flower Color: White Bloom Time: June to September Description Achillea millefolum is a flowering plant, up to 2.6 feet (80 cm) tall, with branched, bright green stalks at the peak. Leaves are alternately arranged and hairy. The white flower heads are about 0.12 inch (3 mm) wide, 0.2 inch (5 mm) long and are combined in thyroid tassel. How to Grow and Care It is most often propagated by division, so chances are you’ll buy your Yarrow as a plant. Space your plants 12 to 24 inches (30 to 60 cm) apart if you’re planting more than one plant. You can also start your Yarrow from seed. Start seeds indoors about six to eight weeks before your last frost date. Sow the seeds in moist, normal potting soil. The seeds should just barely be covered by the potting soil. Place the pot with the seeds in a sunny and warm location. The seeds should germinate in 14 to 21 days, depending on the conditions. You can speed up the germination by covering the top of the pot with plastic wrap to keep in moisture and heat. Remove the plastic wrap once the seeds have sprouted. Regardless of whether your plants are grown from seed or bought as full plants, you will want to plant them in full sun. They thrive in a wide variety of soils but do best in well drained soil. Yarrows will even grow in very poor dry soils with low fertility soil. Origin Native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America.

Scientific Name Acacia melanoxylon R.Br.
Common Names Australian Blackwood, Black Acacia, Sally Wattle, Lightwood, Hickory, Mudgerabah, Tasmanian Blackwood, Black Wattle, Blackwood Acacia Synonyms Acacia arcuata, Acacia melanoxylum, Mimosa melanoxylon, Mimosa melanoxylum, Racosperma melanoxylon, Racosperma melanoxylon Scientific Classification Family: Fabaceae Subfamily: Mimosoideae Tribe: Acacieae Genus: Acacia Flower Color: Creamy Bloom Time: From late winter into spring
Description Acacia melanoxylon is a very quick-growing tree up to 40 feet (12 m) tall, with a 20 feet (6 m) wide and in maturity an oval shaped crown. It has rough dark gray bark with vertical fissures and mid-green leaf-like flattened stems, called “phyllodes”, that are up to 5 inches (13 cm) long by about an inch (2.5 cm) wide, with one margin straight and the other curved. Small creamy flowers are in a small ball-like cluster from late winter into spring and are followed by thin curling seed pods that hang in brownish sheaves. Acacia melanoxylon - Australian Blackwood
How to Grow and Care Acacia requires full sunlight and grows in nearly any type of soil, including sand, clay, or soil that is highly alkaline or acidic. Although Acacia prefers well-drained soil, it tolerates muddy soil for short periods of time. Acacia is basically a plant-it-and-forget-it type of tree, although a young tree may need protection from wildlife while it develops its defense system. During the first year, the tree benefits from an orchid fertilizer every three to four weeks. After that time, you can feed the tree a general purpose fertilizer once every year, but it isn’t an absolute requirement. Acacia requires little or no water. Acacia may need occasional pruning during the dry months. Avoid pruning leafy, green areas and trim only dead growth. Although the tree is disease-resistant, it can sometimes be affected by a fungal disease known as anthracnose. Additionally, watch for pests such as aphids, thrips, mites and scale. Origin Native to Australia.

Scientific Name Abutilon pictum (Gillies ex Hook. & Arn.) Walp.
Common Names Redvein Abutilon, Painted Indian Mallow, Red Vein Indian Mallow, Flowering Maple, Redvein Flowering Maple, Red Vein Chinese Lanterns, Chinese Lantern Synonyms Sida picta (basionym), Abutilon striatum, Abutilon pleniflorum, Abutilon pseudostriatum, Abutilon thompsonii, Abutilon thompsonii, Abutilon venosum, Sida striata Scientific Classification Family: Malvaceae Subfamily: Malvoideae Tribe: Malveae Genus: Abutilon
Flower Color: Yellow to orange-red Bloom Time: April to September Description Abutilon pictum is an evergreen shrub, up to 16 feet (5 m) tall and up to 6 feet (1.8 m) wide. The leaves are 3- to 5-lobed and up to 6 inches (15 cm) long. The flowers are yellow to orange-red, bell shaped, with prominent dark red veining, and five petals, up to 1.6 inches (4 cm) long. It blooms from April to September. Abutilon pictum - Painted Indian Mallow How to Grow and Care
Abutilon is not an especially difficult plant to grow. During warmer, dry winters, they are sometimes affected by spider mites, and they are known for leggy growth. To encourage bushy growth, prune the plant by 25 percent to 40 percent in the late winter, right when new growth is about to start. Also, throughout the summer, occasionally pinch off new growth to encourage healthy growth. When pruning, make sure to stagger your cuts and remove some large branches to open the plant’s canopy. As a final note, these plants dislike acidic soil, so it is not necessary to add additional lime to your potting mix. Instead, stick with the basic peat-based potting soil and make sure to refresh it as the mixture decomposes and becomes more acidic over time. Abutilon is a relatively fast-growing plant, especially when they’re young. Consequently, younger plants might need to be repotted twice a year, once at the beginning of the growing season and once in the middle. Older plants, however, benefit from being slightly pot-bound, so should be repotted either every other year or yearly into only slightly larger pots. Pot-bound plants tend to grow more vigorously and bloom better. Origin Native to southern Brazil and Argentina, and Paraguay and Uruguay.

Scientific Name Abelmoschus esculentus (L.) Moench Common Names Okra, Okro, Ladies’ Fingers, Ochro Synonyms Hibiscus esculentus (basionym), Abelmoschus bammia, Abelmoschus longifolius, Abelmoschus officinalis, Abelmoschus praecox, Abelmoschus tuberculatus, Hibiscus ficifolius, Hibiscus hispidissimus, Hibiscus longifolius, Hibiscus praecox
Scientific Classification Family: Malvaceae Tribe: Hibisceae Genus: Abelmoschus Flower Color: White to yellow Bloom Time: Blooms freely throughout the growing season to frost Description Abelmoschus esculentus is a perennial, often cultivated as an annual in temperate climates, and often grows up to 6.7 feet (2 m) tall. The leaves are up to 8 inches (20 cm) long and broad, palmately lobed with 5 to 7 lobes. The flowers are up to 3.2 inches (8 cm) in diameter, with 5 white to yellow petals, often with a red or purple spot at the base of each petal. They last only for one day, but plants bloom freely throughout the growing season to frost. The fruit is a capsule up to 17.2 inches (18 cm) long with pentagonal cross-section, containing numerous seeds.
Hardiness USDA hardiness zone 5a to 11b: from −20 °F (−28.9 °C) to 50 °F (+10 °C). How to Grow and Care Okra needs full sun. It will grow in ordinary garden soil but does best in fertile loam, particularly where a nitrogen-fixing crop, such as early peas, grew previously. In the South, plant the first crop in the early spring and a second crop in June. In short-season areas, start plants indoors 6 weeks before setting them out (3 to 4 weeks after the last frost date). Sow two seeds per peat pot and clip off the weaker seedling. When seeding Okra directly in the ground, wait until after the soil has warmed and the air temperature is at least 60°F (16°C). Use fresh seed, and soak it overnight or nick each seed coat with a file to encourage germination. Sow seed 0.5 inch (1.2 cm) deep in light soil and 1 inch (2.5 cm) deep in heavy soil; spacing is 3 inches (7.5 cm) apart in rows 3 feet (90 cm) apart. Thin seedlings to 18 to 24 inches (45 to 60 cm) apart, always leaving the strongest of the young plants.
Origin The geographical origin of Okra is disputed, with supporters of West African, Ethiopian, and South Asian origins. The plant is cultivated in tropical, subtropical and warm temperate regions around the world.

GARDEN designers know that when it comes to annuals, it's not just about the flowers — foliage matters, too. And when it comes to foliage, coleus tops the list. Though it has fallen in and out of favor over the past couple of centuries, this member of the mint family is popular again, and the selection is better than ever. When breeders try to create new plants, the focus is often on new color combinations. In recent years, other considerations have become prominent, too:
sun-tolerance delayed flowering more prolific branching special growth habits, such as compact and trailing How to Choose The variability in patterns is amazing, with solid colors, splashes, blotches, streaks, flecks, margins and veins. Color intensity varies, depending on sunlight, heat sensitivity and other conditions. The term "sun coleus" refers to selections that tolerate more sun. The varieties with dark leaves tend to tolerate more sun, while lighter varieties need more shade to minimize leaf scorch. Morning sun and dappled afternoon shade tends to maintain consistent foliage coloration. Too little light will encourage a weak-stemmed, less vigorous plant without the best color. Another variable to consider is leaf texture, which includes large, small, twisted, elongated, scalloped, lobed, finger-like, and "duck's foot" — they resemble webbed feet. Coleus can be grouped into three plant forms: upright, rounded and trailing. Frequent snipping, pinching and trimming can help modify form although the trailing varieties have great value at the edge of a planter or in a hanging basket.
Planting and Care Coleus has long been considered a shade plant but the best leaf color is achieved with morning sun and some degree of afternoon shade. Many varieties do well in both shade and part-sun. Some can take quite a bit of sun as long as they are not allowed to dry out. Avoid overly damp soils, which can cause leaf drop and encourage disease. Plant coleus after danger of frost has passed when soil temperatures have warmed sufficiently and evening temperatures are above 60 degrees F. Feed plants regularly with a water-soluble fertilizer, especially if they are growing in containers. To maintain plant form, pinch back every few weeks to prevent flower formation. Pinch just above a set of leaves or branching junction for the best appearance; don't leave a stub. Some gardeners leave the small flowers, but it's best to pinch them off to direct more energy into stem and foliage growth. Coleus left to flower may lose vigor as the plant puts energy into seed production.
Getting More Plants Raising coleus from seed is relatively easy. Plan to sow them indoors, eight to 12 weeks before the last frost date in your area. Because seeds require light to germinate, sow them on the surface. Be sure to monitor water levels carefully. For best results, use a seedstarting system and read How to Start Seeds. Overwintering coleus plants as houseplants is another way to get more plants. Temperatures near 70 degrees F. are required. Rotate plants and pinch back as needed to maintain form. Use grow lights to provide adequate light. Designing With Coleus Use solid-color coleus varieties, such as Redhead and Lime Delight Premium Sun (both bred for the sun), to make a bold statement in the garden. Try multicolored varieites for "color echoes" that complement neighboring plants that have similar (or contrasting) flower and/or foliage colors. The repetition of certain coleus colors and form can lend unity and harmony in the garden. While a solitary specimen can add a "punch" of color, consider the impact of mass planting as well. Foliage with lighter colors can illuminate shady locations while dark colors in the same setting will create depth and contrast. Coleus in Containers Coleus do well in pots and planters, as long as they are planted in free-draining potting soil, fertilized regularly and given the right amount of sun. Avoid windy locations because coleus can be prone to breakage. Feed regularly during the growing season, following the rate recommended on the package. Coleus do not show their best color if over-fertilized, so be conservative and consistent. You may want to consider self-watering planters, especially in sunny locations. Coleus can be included in hanging baskets, too. Some of the trailing selections will flow nicely over the edge. Compact, bushy types can be used in the center of the basket. Keep in mind that coleus are thirsty and a hanging basket can dry out quickly — choose a self-watering basket for best results.

You may have heard that you can change the color of a hydrangea's flowers by adjusting soil pH. But there's a little more to it than that. First of all, not all hydrangeas produce blue flowers. Hydrangeas with white or cream flowers, such as Annabelle hydrangeas, oakleaf hydrangeas and members of the PeeGee family, can only produce white or cream flowers. Sometimes their blooms take on a pink tinge at the end of the season, but that's about as colorful as they get.
Hydrangeas with bloom colors that range from pink through blue and purple usually belong to the hydrangea cultivars known as mopheads and lacecaps. These types of hydrangeas have the interesting ability to change the color of their blooms based on the chemistry of the soil. When grown in alkaline soil, the bloom colors are pinker. When grown in acidic soil, the bloom colors are bluer. Because it's the soil chemistry that determines the bloom color, the variety names given to these types of hydrangeas means very little when it comes to bloom color. For instance, Nikko Blue, Pretty in Pink, Forever Pink and Blue Deckle, all have an almost equal chance of blooming pink or blue, depending on the soil they are planted in. So remember that even if you purchase a hydrangea in bloom, you cannot be sure the plant will produce the same color flowers once it's growing in your garden.
To manipulate the color of a hydrangea's blooms, you need to manipulate your soil's pH level and mineral content. This is not something you do just once. In order to maintain growing conditions that result in a specific bloom color, you may need to apply special soil amendments several times during the growing season (see Adjusting the pH of Your Soil, below, ). To really experiment with the color of a hydrangea's blooms, consider growing the plant in a large pot. Because you will be working with a much smaller amount of soil, it will be much easier to maintain the desired soil chemistry. Start by testing the pH of your soil. This will give you an idea how much of an uphill battle you'll be waging. Be mindful that the health of the plant should be your first priority. It's quite difficult to make a dramatic change in soil pH, and doing so can adversely affect the overall health of the plant. To encourage blue hydrangea flowers, grow the plant in soil that has a pH of 5.2-5.5. If your soil is more alkaline, you can lower the pH by applying Soil Acidifier at the rate specified on the package. Soil pH can also be lowered (more gradually) by applying an acidic organic mulch, such as pine needles or pine bark.
If the pH of your soil is naturally quite high (alkaline) it will be very difficult to get blue flowers — even if there's plenty of aluminum in the soil. Alkaline soil tends to "lock up" the aluminum, making it unavailable to the plant. (However, you can grow fabulous pink hydrangeas!) If you prefer pink blooms, your hydrangea should be deprived of aluminum by growing it in an alkaline soil with a pH of 6.0-6.2. You can apply a high-phosphorus fertilizer to further discourage the uptake of aluminum. To raise the pH of a naturally acidic soil, apply Garden Lime at the rate specified on the package.
