Scientific Name Ferraria crispa Burm.
Common Names Black Flag, Starfish Lily, Sea Spider Iris Synonyms Ferraria obtusifolia, Ferraria undulata Scientific Classification Family: Iridaceae Subfamily: Iridoideae Tribe: Irideae Genus: Ferraria
Flower Color: Brown and pale yellow Bloom Time: Late spring to early summer Description Ferraria crispa is a small perennial, up to 1.5 feet (45 cm) tall, with remarkable, velvety textured flowers that have intricately frilled and crisped margins on their 3 long and 3 short petals. The flowers are also strongly marked and mottled in shades of brown and pale yellow and unfortunately have an unpleasant scent. The flowers are up to 2 inches (5 cm) in diameter, produced in late spring to early summer on 2 to 3 stems per corm, and are only open in fine weather.
How to Grow and 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. Origin Native to South Africa.

Scientific Name Ferocactus glaucescens (DC.) Britton & Rose
Common Names Blue Barrel Cactus, Glaucous Barrel Cactus Synonyms Bisnaga glaucescens, Echinocactus glaucescens, Echinocactus pfeifferi, Ferocactus pfeifferi Scientific Classification Family: Cactaceae Subfamily: Cactoideae Tribe: Cacteae Genus: Ferocactus
Flower Color: Yellow Bloom Time: Late spring and summer Description Ferocactus glaucescens is a generally solitary, barrel cactus with bluish green stems up to 22 inches (55 cm) tall and 20 inches (50 cm) in diameter, 11 to 15 ribs, 0 or 1 central spine, and straight, light yellow 6 or 7 radial spines, up to 1.6 inches (4 cm) long. The flowers are lemon yellow, funnel-shaped and up to 1.6 inches (4 cm) in diameter. The plants start flowering when about 5 inches (12.5 cm) in diameter. The fruits are white, 0.8 inch (2 cm) long with the remnants of the flowers attached.
How to Grow and Care Choose a planting location that receives direct sun during all or most of the day. Water the cactus at the time of planting to anchor it into the soil. Plant your Barrel Cactus in early spring before new roots begin to form in late June and early July. The roots may appear dry, but that is typical before new growth begins. Dig a hole deep enough for the plant’s roots and amend it as needed to provide fast-draining soil. A good soil mixture includes 10 percent native soil, 45 percent washed sand or pumice and 45 percent compost. Ferocactus thrives in poor and arid soil. Water the cactus at the time of planting to anchor it into the soil. Water again only if the weather in your area is unseasonably dry and if normal spring or winter rainfall doesn’t occur. Origin Native to eastern Central Mexico.

Scientific Name Vitis vinifera L.
Common Names Common Grape Vine, Grape Vine, Wine Grape, European Grape Synonyms Cissus vinifera Scientific Classification Family: Vitaceae Genus: Vitis
Flower Color: Yellow, white Bloom Time: Spring Description Vitis vinifera is a liana growing up to 35 yards (32 m) in length, with flaky bark. The leaves are alternate, palmately lobed, up to 8 inches (20 cm) long and broad. The fruit is a berry, known as a grape. In the wild species it is up to 0.25 inch (6 mm) in diameter and ripens dark purple to blackish with a pale wax bloom. In cultivated plants it is usually much larger, up to 1.2 inches (3 cm) long, and can be green, red, or purple (black). There are currently between 5,000 and 10,000 varieties of Vitis vinifera grapes though only a few are of commercial significance for wine and table grape production.
How to Grow and Care Choose a sunny, well-drained position, and at planting time, dig in plenty of organic matter, including a good shovelful of compost. Dig the hole large enough for the roots to spread, and backfill with soil and compost, pressing around the area to get rid of air holes. Water in well and make sure, with a grafted vine, that the graft union is not below the soil – it should be at least 4 inches (10 cm) above the surface. In early spring, fertilize with a complete fertilizer to establish the new vine, and repeat each year in spring and summer. Grapevines are well adapted to growing in dry conditions and a drip-irrigation system will deliver water efficiently and adequately. It is a better method than watering overhead, as this can lead to fungal problems, such as mildew on the leaves and rotting fruit. Regular watering is done from September to January, and then withdrawn after the fruit is harvested. Origin Native to the Mediterranean region, central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran.

Flower Color: Purple, blue, yellow or white Bloom Time: April to September Description Viola tricolor is a small, annual or short lived perennial plant of creeping and ramping habit, up to 6 inches (15 cm) tall. The stems are light green to purplish green, glabrous, and angular. Leaves are simple, lobed or unlobed but not separated into leaflets and medium green in color. The flowers are up to 0.6 inch (1.5 cm) in diameter and different in color: purple, blue, yellow or white. It flowers from April to September.
How to Grow and Care Viola plants prefer cool to warm climates, and wilt a bit in mid-summer heat. In warmer areas, we recommend partial shade. They tolerate a variety of soils. Add a general purpose fertilizer when planting them, then once a month after that. Once your Viola plants are established, they should grow well, even if left unattended. Soil should be moist, but not wet. Water them during dry periods, once or twice per week. Keep them well weeded. Remove spent blooms to promote additional blooms, and extend the blooming period. This will also keep the appearance neat and beautiful. Violas are grown from seeds. They like full to partial sun. Viola can be directly seeded into your flower garden or seeded indoors for transplanting later. For spring blooms, you need to start your Viola in pots and containers indoors six to eight weeks before the last frost. Origin Native to Europe.

Scientific Name Victoria amazonica (Poepp.) J. C. Sowerby
Common Names Santa Cruz Water Lily, Water Platter Synonyms Victoria argentina, Victoria regia var. cruziana Scientific Classification Family: Nymphaeaceae Genus: Victoria
Flower Color: White and pink Bloom Time: Summer Description Victoria cruziana is a giant, water lily with massive, floating mid-green lily pads that can reach up to 8 feet (2.4 m) across and can support the weight of a small adult. Its leaves are reddish purple and softly hairy on the underside. The ephemeral, pineapple-scented blooms appear in summer, lasting only two nights. The flowers are up to 16 inches (40 cm) in diameter, white the first night, turning pink on the second night. Hardiness USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care In the wild the giant waterlily is a short-lived perennial, but at Kew, Royal Botanic Gardens it is raised as an annual from seed planted each January. In summer the flowers are hand-pollinated and then placed in a bag. This enables easy collection of the resulting seed, in the autumn. The seeds must be kept moist, preferably in water, all the time. To prevent premature germination, or death, they are kept at a constant temperature of 15 °C. In order to begin germination it is sometimes necessary to nick the seed with a scalpel, after which germination occurs in ten days. In January the newly germinated seed is pricked out into a tiny pot which is kept in water. As the plant grows, potting on into larger pots is carried out until the plant occupies a one ton pot. Loam is used as a substrate, the key factors for this choice being that it does not float, it is rich in nutrients and it has the capacity to enclose the fertilizer that is contained in the ‘feed bombs’ given to the plant. Origin Native to South America, primarily Argentina and Paraguay.

Scientific Name Vachellia karroo (Hayne) Banfi & Galasso
Common Names Sweet Thorn, Common Acacia, Karoo Thorn Synonyms Acacia karroo (basionym), Acacia capensis, Acacia dekindtiana, Acacia hirtella, Acacia inconflagrabilis, Acacia reticulata, Mimosa reticulata Scientific Classification Family: Fabaceae Subfamily: Mimosoideae Tribe: Acacieae Genus: Vachellia
Flower Color: Yellow Bloom Time: Early summer Description Vachellia karroo is a shrub or small to medium-sized tree which grows up to 40 feet (12 m) tall. It has a rounded crown, branching fairly low down on the trunk. It is variable in shape and size. The bark is red on young branches, darkening and becoming rough with age. Sometimes an attractive reddish color can be seen in the deep bark fissures The leaves are finely textured and dark green. The thorns are paired, grayish to white and are long and straight. On mature trees, the thorns may be quite short. The flowers appear in early summer in a mass of yellow pompons. The seed pods are narrow, flat and crescent shaped. They are green when young becoming brown and dry.
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 southern Africa from southern Angola east to Mozambique, and south to South Africa.

Most people are introduced to Orchids through Phalaenopsis Orchids. These are the thick-leaved plants with elegant, arching sprays of blooms that can be seen in so many design magazines and sitting on coffee tables across America. There are about 60 true species of Phalaenopsis; they are native to tropical Asian countries including the Philippines, Borneo, Java and elsewhere. These plants have been extensively hybridized, and there are thousands of Phalaenopsis hybrids, ranging from the stark, classic white hybrid (often called a Moth Orchid) to jewel-like miniatures with clouds of yellow and candy pink blooms.
Growing Conditions and General Care Light: Phalaenopsis are low-light Orchids and will thrive in a east window, or a shaded southerly or westerly exposure. They do not like direct sunlight and will scorch. They also will do well under common grow lights, positioned about a foot off the plant. A well-grown phal will have darker green leaves on top and streaks of red or burgundy on the undersides.
Water: The Phalaenopsis is a Monopodial Orchid that grows from a single stem. It does not have the large water-storing pseudobulbs found on Sympodial Orchids, although its leaves can store some water. Thus, the plant has a lower tolerance for drought. During the growth season, water the plant whenever its exposed roots turn silvery white, usually weekly. Try to keep the potting media slightly damp. During the flowering season, you can cut the water back to every other week. The higher the humidity, the more important it is to maintain a good air flow around the roots and leaves. Fertilizer: During the growing season, fertilize with a weak Orchid fertilizer weekly (weakly weekly, as the growers say). Cut fertilizer back to once a month during the winter and flowering season. Some growers like to give the plant a boost of blooming fertilizer in September or October to provoke a flower spike.
Temperature: Generally, Phalaenopsis are considered a warm-house plant. During active growth, they like temperatures between about 75°F and 85°F (24°C and 30°C), but they can adapt to a normal house temperature of 65°F to 70°F (18°C to 21°C). The higher the temperature, the greater the plant’s need for humidity. However, they also like a nice contrast between night and day temperatures. Blooming Phalaenopsis typically bloom in the late winter or early spring. Their long-lasting flowers are held on arching branches and open successively. A single multi-branching flower spike can have more than 20 flowers. Individual Phalaenopsis flowers can last for weeks. To induce a flower spike, the plant needs a few cooler nights, down to 55°F (13°C). The plants will not bloom well without this temperature contrast.
Potting and Media Phalaenopsis can be grown in most Orchid potting media, including chunks of pine bark, clay aggregate pellets, charcoal, perlite, sphagnum moss, and styrofoam. They can also be grown in hanging baskets or mounted on slabs in a greenhouse-type environment. As with all Epiphytic Orchids, they should be planted in free-draining containers. Repot Phalaenopsis in spring, after the bloom is done. Adult Phalaenopsis can often go for two years or more before they need to be repotted.
Grower’s Tips Phalaenopsis are generally very rewarding plants. They are not demanding and, in the right conditions, they will reward the grower with months of showy blooms. It is vitally important, however, that water never be allowed to rest in the growing tip of the plant. This will cause the new leaves to rot, and the plant will die. Thus, they should only be watered in the morning. As with all Orchids, the higher the humidity and temperature, the greater the need for turbulent air flow to prevent rot, fungus and diseases. Successful growth means finding the right balance between humidity, temperature, light and air flow.

Cousin to the banana, the Bird of Paradise Flower (Strelitzia) is one of the best known of all the tropical flowers. Who hasn’t walked into a swanky hotel or event and seen magnificent table centerpieces built about these remarkable flowers? Surprisingly, Bird of Paradise are easier to grow than many tropical plants. The plant is a vigorous, rapidly growing indoor plant. They can be moved outside in the summer, and in warmer climes, will thrive for half the year outside. They typically flower in the late winter or early spring, but under optimal conditions, will flower at various times.
Growing Conditions Light: Bright light, even including some direct sunlight, to bloom well. However, only habituated plants can handle direct, midday summer sun. Water: Keep soil continuously moist throughout the year. High humidity is preferred. Temperature: Above 60ºF (15ºC) is preferred in the winter. This is not a cold-tolerant plant. Soil: Rich, well-drained potting mix. Fertilizer: Feed in spring with slow-release pellets or weekly during growing season with liquid fertilizer.
Repotting These are rapid-growing plants that need to reach a certain size before they’ll bloom. Repot every spring into a larger pot and make sure to give it room to get big. Propagation By division of underground rhizome during repotting. Can be grown from seed, but division is so easy, why bother?
Grower’s Tips Strelitzia is a genus of about 5 or 6 species (depending on who you listen to). Strelitzia reginae is the most well known species and is frequently grown as house plants. It is a beautiful plant and can be very successfully grown inside. The biggest drawback is typically its size (they grow up to 5 feet/1.5 m) and the fact that plants need 3 to 5 years before they will flower. They work well in massed plantings or as specimen plants, and their flowers will rise above the foliage for an impressive display. The trick to successful growth is providing lots of bright light (with some gentle direct sun), water, warmth and food.
