Scientific Name Laburnum anagyroides Medik.
Common Names Common Laburnum, Golden Chain, Golden Rain, Golden Chain Tree, Laburnum, Peatree Synonyms Cytisus alschingeri, Cytisus laburnum, Laburnum vulgare Scientific Classification Family: Fabaceae Subfamily: Faboideae Tribe: Genisteae Genus: Laburnum
Flower Color: Yellow Bloom Time: Late spring Description Laburnum anagyroides is small deciduous tree or large shrubs up to 30 feet (9 m) tall. The branches are spreading, smooth bark, dark green in color. Leaves are trifoliate, up to 2.8 inches (7 cm) long, comprised of alternate leaflets, each up to 3.2 inches (8 cm) long and up to 1 inch (2.5 cm) wide. The flowers are golden yellow, sweet scented, densely packed in pendulous racemes up to 10 inches (25 cm) long, and typically bloom in late spring.
How to Grow and 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. Origin Native to Central and Southern Europe.

Scientific Name Crocus tommasinianus Herb.
Common Names Early Crocus, Woodland Crocus, Tommasini’s Crocus, Botanical Crocus, Snow Crocus, Lilac Tommy, Spring Bulbs, Spring Flowers Synonyms Crocus serbicus, Crocus vernus var. tommasinianus Scientific Classification Family: Iridaceae Subfamily: Crocoideae Genus: Crocus
Flower Color: From lilac to deep purple Bloom Time: Early spring Description Crocus tommasinianus is a cormous perennial with a lilac flower, and is one of the smaller of the cultivated species of the genus Crocus. It has long tubed flowers, up to 1.6 inches (4 cm) long, which appear in early spring, as the narrow leaves emerge. The flowers vary from lilac to deep purple, sometimes paler outside.
How to Grow and Care Crocus bulbs need well drained soil in a sunny to partially sunny location. They thrive in a soil pH of 6 to 7 and are tolerant of a wide range of soils. You may even grow Crocus in the lawn but be careful as they will naturalize and spread to become a potential nuisance. Plant the Crocus bulbs in groups in the garden bed for impact or even under trees, as they need little root space. Bulbs are planted 3 inches (7.5 cm) deep and 3 to 4 inches (7.5 to 10 cm) apart. Provide mulch over the planting area in very cold zones but rake it away in early spring so the flowers can emerge. Gardeners in zones where the winters are too harsh or too warm to plant in fall can force the Crocus bulbs indoors in time for a spring planting. Animals can be a big problem with Crocus bulbs. Squirrels and other rodents will dig up the bulbs and eat them, and deer will graze on the early foliage. You can cover the spring bulb bed with wire mesh to prevent squirrel damage, and there are deer repellents you can try to prevent their feeding on your flowers. Origin Native to Bulgaria, Hungary, Albania, and the former Yugoslavia.

Scientific Name Crocus sativus L.
Common Names Saffron, Saffron Crocus, Autumn Crocus Synonyms Crocus officinalis, Crocus orsinii, Crocus pendulus, Crocus setifolius, Geanthus autumnalis, Safran officinarum Scientific Classification Family: Iridaceae Subfamily: Crocoideae Genus: Crocus
Flower Color: Lilac-purple Bloom Time: Autumn Description Crocus sativus is a perennial plant, up to 6 inches (15 cm) tall. Each corm produces several upright, cup-like, lilac-purple flowers with dark purple veins that bloom in early to mid-autumn. Each flower has three long style branches tipped with reddish-orange stigmas. Flowers close at night and open up in the morning. Basal, grass-like leaves appear slightly prior to bloom.
How to Grow and Care In areas where Saffron Crocus are reliably hardy—USDA Zone 6 through 8 in the South, 6 through 9 in the West—you should plant the corms as soon as you receive them. Saffron Crocus do best in full sun and well-drained soil that is moderately rich in organic matter. Ideally, the site should be relatively dry in summer, when the corms are dormant. Plant the corms 4 inches (10 cm) deep and 4 inches (10 cm) apart. If gophers, mice, or voles are a problem in your garden, plant the corms in containers or line the bed with hardware cloth or a similar wire mesh. Flowers generally come up 6-8 weeks after planting, although occasionally they wait until the 2nd fall to appear. Bloom lasts about 3 weeks. The grass-like leaves may emerge either with the flowers or soon after they appear. Sometimes they wait until the following spring. In either case, the leaves persist for 8-12 weeks, then wither and vanish, leaving no trace of the corms below until the flowers appear again in fall. It’s not a bad idea to mark the area where you’ve planted your corms, so you don’t inadvertently dig them up while planting something else. Origin Native to southern Europe and Asia.

Scientific Name Crassula ovata (Miller) Druce
Common Names Money Tree, Money Plant, Jade Plant, Jade Tree, Friendship Tree, Lucky Plant, Dollar Plant, Pink Joy Synonyms Crassula argentea, Crassula portulacea, Crassula obliqua, Crassula articulata, Crassula nitida, Crassula lucens, Cotyledon ovata, Cotyledon lutea, Toelkenia ovata Scientific Classification Family: Crassulaceae Subfamily: Crassuloideae Genus: Crassula
Flower Color: White to pink Bloom Time: Spring Description Crassula ovata is a large well-branched, compact, rounded, evergreen shrub, 3 – 6 feet (90 – 180 cm) tall with glossy, dark grey-green, oval, succulent leaves and rounded heads of white to pink star-shaped flowers in early spring. The stem is stout and gnarled and gives the impression of great age, and its branches are also short and stubby but well-proportioned. Branches are succulent, grey-green in color and in older specimens the bark peels in horizontal brownish strips. The leaves are up to 2 inches (50 mm) long and up to 1 1/2 inches (38 mm) wide, egg-shaped to elliptic, often with a red margin and a somewhat pointed end. They are in opposite pairs, the one pair arranged at right angles to the next, and they are clustered towards the ends of the branches.
How to Grow and Care Easy to grow in container, best in full sun but will tolerate part sun. It need well-drained soil with a neutral pH. Water regularly form spring to autumn and allow soil to dry out before watering again. During the winter months, water only enough to keep the leaves from shriveling. Most common reason for failure is overwatering. Propagating is achieved with leaf or stem cuttings which are placed into a soil mix, then wait until they show some growth. Before placing them in soil mix you will prevent potential problems from the sap seeping out by allowing them to dry on a windowsill, for a few days or so. Origin Native to South Africa.

Scientific Name Crassula ‘Morgan’s Beauty’
Common Names Morgan’s Beauty Synonyms Crassula ‘Morgan’s Pink’ Scientific Classification Family: Crassulaceae Subfamily: Crassuloideae Genus: Crassula
Flower Color: Pinkish Bloom Time: Winter to spring Description Crassula ‘Morgan’s Beauty’ is a compact succulent plant, perfect for small plant containers. Grows up to 4 inches (10 cm) in height and up to 4 inches (10 cm) wide. It has large, thick, flat, silvery-green leaves with a blush of blue and pink. The flowers are pinkish and grow in small, short-stemmed clusters. It blooms in winter to spring, but may also occur other times of year.
How to Grow and Care Crassula are easy to grow, but they are susceptible to mealy bugs and fungal diseases. As with all succulents, overwatering is sure to be fatal, so err on the side of too dry rather than too wet. Never let your Crassula sit in water. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes. Repot as needed, preferably during the warm season. To repot a succulent, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot. Crassula are generally started by division, offsets or leaf cuttings. Origin Hybrid of Crassula falcata and Crassula mesembrianthemopsis.

Scientific Name Costus curvibracteatus Maas
Common Names Orange Tulip Ginger, Dwarf Orange Ginger, Spiral Ginger Scientific Classification Family: Costaceae Genus: Costus
Flower Color: Orange Bloom Time: Late spring to early winter Description Costus curvibracteatus is an evergreen perennial up to 10 feet (3 m) tall. The leaves are dark green, obovate to elliptic, up to 14 inches (35 cm) long and up to 4 inches (10 cm) wide. They are glossy and glabrous above, but hirsute on the edges and underside, and alternately arranged on a spiraling stem, which has a diameter up to 1 inch (2.5 cm). Glossy, overlapping bracts form a terminal inflorescence, that is spike-shaped to ovoid. The bracts are red to orange, usually becoming more orange at the apex, which curves outward. The inflorescence is quite variable in size, ranging from 1.6 to 7 inches (4 to 18 cm) long and 1.2 to 3.4 inches (3 to 9 cm) broad. During flowering, small, hermaphroditic yellow or orange tubular florets emerge among the bracts. They are usually about as long as the bracts but can be substantially longer.
How to Grow and Care Costus fall into the tropical category, so if you do well with philodendrons and other tropical plants, you should be able to grow Costus without too much issue. They aren’t terribly picky about their light, but the key to successful growth is lots of water and lots of fertilizer to keep up with their heavy demands. If your plant starts to suffer from brown leaf margins, it most likely is being underwatered or exposed to cold drafts. Try to raise the humidity and increase the water. Costus are susceptible to mealybugs and aphids. Keep a careful eye on your plants and inspect them to catch infestations early and treat immediately. Severely infected plants should be discarded. Depending on the species, you’ll probably need to repot your Costus annually, in the beginning of the growing season. If you want to keep it a manageable size, use this as an opportunity to divide the rhizome and refresh your potting soil, but keep it in the same size pot. Some of the larger species can grow to 10 feet (3 m) or more, so be aware of the potential size issue. Origin Native to Costa Rica and Panama.

Scientific Name Coreopsis tinctoria Nutt.
Common Names Plains Coreopsis, Annual Coreopsis, Golden Tickseed, Painted Tickseed, Calliopsis, Garden Tickseed, Goldenwave Synonyms Calliopsis cardaminifolia, Coreopsis cardaminifolia Scientific Classification Family: Asteraceae Subfamily: Asteroideae Tribe: Coreopsideae Genus: Coreopsis
Flower Color: Yellow and maroon or brown Bloom Time: Mid-summer Description Coreopsis tinctoria is an annual plants, up to 4 feet (1.2 m) tall and up to 18 inches (46 cm) wide, with smooth, stiff, branching stems. Leaves are pinnately-divided, glabrous and tending to thin at the top of the plant, up to 3 inches (7.5 cm) long. Flowers are brilliant yellow with maroon or brown centers of various sizes, up to 2 inches (5 cm) in diameter. Flowering typically occurs in mid-summer. The small, slender seeds germinate in fall or early spring.
How to Grow and Care Most varieties are very easy to grow and are not particular about soil quality or soil pH. Many can be grown from seed, either started indoors, 4-6 weeks before your last expected frost, or direct seeded outdoors. Many will seed themselves, however the hybrid varieties do not grow true to seed. Coreopsis will need regular water when first planted, until they are established. After that, they are quite drought tolerant. Deadheading will keep the plants blooming throughout the summer. Some of the smaller flowered varieties are difficult to deadhead and you may prefer to shear the plants, once the first flush of flowers fade. They will fill in quickly. Most Coreopsis plants will form tidy clumps, but some of the taller species may require staking to look attractive, especially if grown in partial shade. Although they are rugged plants, they don’t tend to live more than 3 to 5 years. A decrease in flowering is a signal it is time to divide the plants or plant some new ones from seed. Origin Native to Canada, Northeast Mexico, much of the United States.
