Scientific Name Graptopetalum superbum (Kimnach) Acev.-Rosas Common Names Beautiful Graptopetalum Synonyms Graptopetalum pentandrum subsp. superbum Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Graptopetalum
Description Graptopetalum superbum forms 5 inch (12.5 cm) wide flat open rosettes with fleshy, thick pale gray-lavender to pink colored leaves that cluster in rosettes at the end of thick stems. Old plants have been noted with stems as long as 7 feet (2.1 m) but more typically this plant remains fairly compact, especially when grown in full sun. In late winter to early spring arise up to 2 foot (60 cm) tall, open multiple-branched inflorescences holding dainty flowers with pale yellow petals with red markings on the tips, and with red sigma lobes and stamens.
How to Grow and Care The rules for Graptopetalums care are similar to those for most succulents. All require lots of sun to look their best. They require gritty porous soil with excellent drainage. Water regularly over the summer months letting the soil dry out between waterings. Minimal water is required over winter. Overwatering is a cause of root rots and the plant can get several pest infestations. Fertlize once during the growing season with a balanced fertilizer diluted to ¼ strength.
The Graptopetalums are generally easy to propagate, by seeds, leaf cuttings or offsets. Any rosette that breaks off has the potential to root and start a new plant. Even a leaf that drops off will root below the parent plant and produce a new rosette quickly.

Scientific Name Crassula barbata Thunb. Common Names Bearded-leaved Crassula Synonyms Crassula barbata subsp. barbata, Crassula lettyae, Purgosea barbata
Scientific Classification Family: Crassulaceae Subfamily: Crassuloideae Genus: Crassula Description Crassula barbata is a biennial or annual rosette-forming succulent, up to 1 foot (30 cm) in height when flowering, usually with one rosette with leaves spirally arranged and old ones remaining attached to stems. Leaves are up to 2 inches (5 cm) long, up to 1.6 inches (4 cm) wide, glabrous but characteristically bearded along the truncate apex with long white spreading hairs. The spikes of small, white to pinkish flowers appear in spring. The rosette will open up as the center extends to form the tall flower stem, and after flowering it will die. Fortunately the dying rosette usually produces a number of basal rosettes which can be detached and grown on to repeat the cycle.
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. Crassula are generally started by division, offsets or leaf cuttings. Plants can be easily propagated from a single leaf: sprout leaves by placing them into a succulent or cacti mix, then covering the dish until they sprout.
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.

Scientific Name Cotyledon tomentosa Harv. Common Names Bear’s Paw Synonyms Cotyledon tomentosa subsp. tomentosa Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Genus: Cotyledon
Description Cotyledon tomentosa is a succulent shrublet, up to 20 inches (50 cm) tall, densely branched. The leaves are flat, succulent and hairy, up to 1.5 inches (3.5 cm) long with 3 – 10 (often reddish) teeth, arranged in a neat row. There are bright green forms with yellowish hairs and grey ones with whitish hairs. The bell-shaped flowers are light yellow, orange to orange-red or pinkish in color.
Hardiness USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C). How to Grow and Care Cotyledons can be divided into two groups. One group consists of evergreen plants with a summer growing period. The other group is made up of deciduous plants, splendidly magnificent with large, solid fleshy stems. The second group grows during the winter, and sheds its leaves during the summer. Cotyledons require a free-draining gritty mix and plenty of sun. They are tolerant of cool, frost-free conditions during the winter if kept dry. Some require pruning to maintain an attractive shape. Cotyledons should be kept in a sunny position. Follow general succulent watering procedures. Be careful of over-watering when they are deciduous.
As succulents go, Cotyledons certainly are rewarding garden and indoor subjects, practically independent of irrigation in all but full desert conditions, though they cannot survive poor light or bad drainage in the wet.

Scientific Name Yucca rostrata Engelm. ex Trel.
Common Names Beaked Yucca, Big Bend Yucca Synonyms Yucca linearis, Yucca rostrata var. linearis Scientific Classification Family: Asparagaceae Subfamily: Agavoideae Genus: Yucca
Description Yucca rostrata is a slow-growing, tree-like Yucca with upright stems and beautiful gray-blue narrow foliage. Although it can branch, it is most often seen with a single trunk, that can grow up to 15 feet (4.5 m) tall. The 2 foot long (60 cm), stiff, slightly waxy, pale bluish-green leaves with yellow margins, form a dense rosette on top of the stems. The old leaves fall off leaving a fibrous soft gray covering on the trunk. Large clusters of white flowers bloom on yellow-orange colored stalks that rise above the foliage on mature plants in late spring.
How to Grow and Care Under the right conditions, Yucca are not difficult plants to grow. They tend to thrive on a little neglect, rather than too much attention. They are especially easy to overwater, and soggy stems are a sign of too much water. The best conditions for Yucca include a sunny corner with relatively low humidity. They are not prone to many pests, although scale can be an issue. Over time, plants will typically lose their lower leaves (in nature, they droop, forming a skirt around the trunk), giving the plant a pleasant “tree-like” appearance.

Scientific Name Kalanchoe manginii Raym.-Hamet & H. Perrier Common Names Chandelier Plant, Beach Bells Synonyms Bryophyllum manginii Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Kalanchoeae Genus: Kalanchoe
Description Kalanchoe manginii is an evergreen succulent perennial growing up to 12 inches (30 cm) tall and wide, with arching branches of rounded, glossy leaves. It bears few flowered, cyme like panicles of tubular, urn-shaped, red flowers, up to 1.2 inches (3 cm) or more long.
How to Grow and Care Kalanchoes are not particularly hard to grow, and the flowering varieties are highly rewarding for their colorful and long-lasting flowers. They prefer bright, sunny locations, especially in the summer growing season. During the winter, consider a south-facing window. Water moderately throughout the summer and reduce watering in the winter. Let the soil surface dry out between waterings, and in the winter, the plant can almost dry out. Watch the fleshy leaves for signs of water distress. They prefer warmth. Do not let fall below 55ºF (12.7ºC). An ordinary potting soil mix is fine. Feed bi-weekly in the summer with a liquid fertilizer, or use slow-release pellets.

Scientific Name Euphorbia obesa Hook. Common Names Basketball, Sea Urchin, Baseball, Living Baseball, Baseball Plant, Gingham, Golf Ball, Vetmensie, Klipnoors
Scientific Classification Family: Euphorbiaceae Subfamily: Euphorbioideae Tribe: Euphorbieae Subtribe: Euphorbiinae Genus: Euphorbia
Description Euphorbia obesa is a spineless, grey-green, dwarf, spherical succulent plant with transverse red-brown or purplish bands. It can grow up to 8 inches (20 cm) tall and up to 3.5 inches (9 cm) in diameter. Rudimentary, caducous leaves. Usually 8, vertical, broad, slightly raised ribs with shallow furrows in between. Small inflorescence borne on short peduncle from stem apices. Female and male flower are born on different plants. The fruit is a slightly three angled capsule, up to 0.3 inch (7 mm) in diameter.
Hardiness USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C). How to Grow and Care Euphorbias are very easy to care for. They require a little pampering to become established, but once they are, they are self-sufficient. In fact, more die from too much care and watering than from neglect. Euphorbias need well-draining soil and lots of sunlight. They are not particular about soil pH, but they cannot tolerant wet soil. Unlike most succulents, Euphorbia does not handle long periods of drought well. It may need weekly watering during the summer. Water whenever the soil is dry several inches below the surface. Water deeply, but don’t let them sit in wet soil, which can cause root rot. Add some organic matter or fertilizer to the planting hole. If you are growing them in containers or your soil is poor, feed with a half-strength fertilizer monthly.
Euphorbia can be grown from seed, but they can be difficult to germinate (or even find). It is usually propagated by cuttings. This can be tricky, because of the exuding sap.
