Scientific Name Adenium boehmianum Schinz Common Names Bushman’s Poison, Bushman Poison, Bushmen’s Arrow Poison
Synonyms Adenium obesum subsp. boehmianum Scientific Classification Family: Apocynaceae Subfamily: Apocynoideae Tribe: Wrightieae Genus: Adenium
Description Adenium boehmianum is a slow-growing succulent, up to 5 feet (1.5 m) tall. It is an erect shrub with barely succulent stems and only modestly fat roots. The glossy, club-shaped leaves are the largest in the genus, several inches long and broad. The flowers are trumpet-shaped and range from white and bright pink to crimson red, up to 2 inches (5 cm) in diameter.
Hardiness USDA hardiness zone 10a to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C). How to Grow and Care These are not difficult plants to grow well, provided they get enough sunlight and warmth. Like all succulents, they cannot tolerate sitting in water, and if you err, do it on the side of too little water. Use a specialized soil mix designed for cacti and succulents. Fertilize during spring and summer with controlled-release fertilizer or liquid fertilizer according to label directions.
Repot as needed, preferably during the warm season. To repot a succulent, make sure the soil is dry before repotting, then gently remove the plant from 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 and antibacterial solution. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot.

Scientific Name Conophytum burgeri L.Bolus. Br. Common Names Burger’s Onion, Little Light Bulbs
Scientific Classification Family: Aizoaceae Subfamily: Ruschioideae Tribe: Ruschieae Genus: Conophytum
Description Conophytum burgeri is an onion-shaped, single-bodied, succulent plant, that is possibly the most unusual of all the species of the Conophytum genus. It is slow-growing and gradually subdivides. It varies in size and can reach up to 1 inch (2.5 cm) in diameter. Unlike other Conophytums, it is spring and summer growing, and is dormant in its pale leaf-sheath during winter. It produces a purple flower in early autumn, with the aroma of honey.
How to Grow and Care Conophytums are usually grown in dish gardens where they spread slowly but make good ornamental plants for window gardening. They also do well in rockeries where they can be grown in crevices. The Conophytum vegetate during the winter season. They must then be kept dry during hot, gradually wet upon autumn arrival: the moisture stimulate the release of new root hairs and the plant will grow for the entire winter season, foliar issuing new pairs from inside the existing ones. Flowering usually occurs in autumn and the color of the flowers is extremely variable from species to species.
The cultivation is quite easy, but care must be taken to avoid excess water and to prevent rot: the plants themselves communicate their water needing with a slight wrinkling of the epidermis. They do not particularly fear the cold weather and can resist also at temperatures of 23°F (-5°C), as long as the soil is completely dry and the temperature returns rapidly to rise.

Scientific Name Crassula ‘Buddha’s Temple’ Common Names Buddha’s Temple
Synonyms Crassula ‘Kimnachi’, Crassula ‘Myron Kimnach’ Scientific Classification Family: Crassulaceae Subfamily: Crassuloideae Genus: Crassula
Description Crassula ‘Buddha’s Temple’ is a very interesting succulent plant. In time it will grow about up to 6 inches (15 cm) tall and start branching at varying levels from the sides of each column. The flat, thin leaves are silvery-grey to grayish-green in color. They are stacked tightly and folded up at the edges, forming a perfectly square column about 1 inch (2.5 cm) in diameter. It develops the most wonderful spherical red, orange or white flower stuck to the top of the plant.
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.

Scientific Name Euphorbia tithymaloides L. Common Names
Devil’s Backbone, Redbird Flower, Buck Thorn, Cimora Misha, Christmas Candle, Fiddle Flower, Ipecacuahana, Jacob’s Ladder, Japanese Poinsettia, Jew’s Slipper, Jewbush, Milk Hedge, Myrtle-Leaved Spurge, Padus-Leaved Clipper Plant, Red Slipper Spurge, Redbird Cactus, Slipper Flower, Slipper Plant, Slipper Spurge, Timora Misha, Zig Zag Plant Synonyms Pedilanthus tithymaloides, Tithymalus tithymaloides Scientific Classification Family: Euphorbiaceae Subfamily: Euphorbioideae Tribe: Euphorbieae Subtribe: Euphorbiinae Genus: Euphorbia
Description Euphorbia tithymaloides is an erect perennial succulent spurge, up to 8 feet (2.4 m) tall and up to 24 inches (60 cm) wide. The leaf is a simple angiosperm leaf, arranged oppositely on the stem. Each leaf is attaching directly to the plant, and up to 3 inches (7.5 cm) long. The leaves are glabrous and acuminate in shape, with smooth edges. The veins in the leaves are pinnate. The plant terminates in a dichotomous cyme, with a peduncle supporting each flower. The floral leaves are split in two parts and ovate, while the involucral bracts are bright red, irregularly acuminate in shape, with a long, thin tube. The male pedicel is hairy, while the female is glabrous. The seed pod is up to 0.3 inches (8 mm) long and 0.35 inches (9 mm) wide, and ovoid in shape. The plant generally flowers in mid-spring.
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. Rooting hormone is recommended with Euphorbias.

Scientific Name Sedum spathulifolium Hook. Common Names Broadleaf Stonecrop, Colorado Stonecrop, Pacific Stonecrop, Spatula-leaved Stonecrop
Synonyms Cotyledon anomala, Gormania anomala, Sedum anomalum, Sedum spathulifolium subsp. spathulifolium, Sedum woodii Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Sedum
Description Sedum spathulifolium is a quite variable succulent plant up to 4 inches (10 cm) tall, producing mats of basal rosettes from a system of rhizomes. The basal leaves are up to 0.8 inches (2 cm) long. They are sometimes coated in a waxy, powdery looking exudate. The inflorescence is a short, erect array of many small flowers with yellow petals. The specific epithet “spathulifolium” refers to the spade-shaped leaves.
How to Grow and Care When growing Sedum, keep in mind that Sedum plants need very little attention or care. They will thrive in conditions that many other plants thrive in, but will do just as well in less hospitable areas. They are ideal for that part of your yard that gets too much sun or too little water to grow anything else. A common name for Sedum is Stonecrop, due to the fact that many gardeners joke that only stones need less care and live longer.
Sedum is easily planted. For shorter varieties, simply laying the plant on the ground where you want it to grow is normally enough to get the Sedum plant started there. They will send out roots from wherever the stem is touching the ground and root itself. If you would like to further ensure that the plant will start there, you can add a very thin covering of soil over the plant. For taller Sedum varieties, you can break off one of the stems and push it into the ground where you would like to grow it.

Scientific Name Dudleya brittonii D. A. Johans. Common Names Giant Chalk Dudleya, Britton’s Dudleya, Silver Dollar Plant
Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Dudleya
Description Dudleya brittonii is a solitary or low slowly-clumping succulent with a beautiful up to 18 inches (45 cm) wide rosette of chalky-white leaves surrounding a thick basal stem. Stout silvery-white, up to 2 foot (60 cm) long spikes arch upward and blush red as the clusters of yellow flowers begin to open in late spring to early summer.
How to Grow and Care Most of the myriad habitats Dudleyas occupy become dry in summer. Therefore, it is important to cut off water to Dudleyas in your garden during summer. Plants grown in sandy soils or containers are exceptions; they will accept infrequent summer watering as long as the soil drains well. The onset of fall or winter rains reawakens Dudleyas from drought-induced dormancy. Their shriveled leaves plump up quickly, growth resumes, and flowering occurs during the next spring or summer. Dudleyas are amazingly resilient; if a portion of a colony sloughs off a cliff face or is uprooted by a burrowing animal, it can persist for months until soil contact is reestablished. Species that naturally grow on ocean bluffs are also salt-spray tolerant. Dudleyas have their share of disease and pest problems. If you can prevent Argentine Ants from introducing mealybugs or aphids to your Dudleyas, they will be healthier.

Scientific Name Gasteria carinata (Mill.) Duval Common Names Bredasdorp Gasteria, Keeled Gasteria, Keeled Ox Tongue Synonyms Aloe angulata, Aloe carinata, Gasteria angulata, Gasteria bijliae, Gasteria parvifolia
Scientific Classification Family: Xanthorrhoeaceae Subfamily: Asphodeloideae Genus: Gasteria
Description Gasteria carinata is a small to medium-sized decumbent to erect Aloe-like succulent. It is highly variable species, up to 7 inches (18 cm) tall and up to 2.6 feet (80 cm) wide. Typically it has sharp, triangular leaves, up to 6 inches (15 cm) long and up to 2 inches (5 cm) wide, mottled in color and channeled on their upper surface. The leaves have sharp points at their tips, and usually have keels in mature plants. The flowers are light pink to white with central green stripes, up to 1.5 inches (4 cm) long.
How to Grow and Care Gasteria are often grouped with Haworthia because the plants have similar cultural requirements. Both are attractive, small succulents that can tolerate somewhat more shade than many succulents, which makes them more suitable as houseplants. Gasteria are susceptible to fungal infections, which usually appear as black spots on the leaves. These are the result of too much humidity or water on the leaves, but they should not spread too quickly. Gasteria have a natural defense mechanism against such fungal attacks and attack the invading organism and seal off the wounded spot. In general, any place where Haworthia and Aloe thrive will be hospitable to a Gasteria.
Gasteria are small, shallow-rooted, and relatively slow-growing. They are often grown in small clusters in wide, shallow dishes. Over time, clusters will naturally enlarge as the mother plant sends off small plantlets.

Scientific Name Jatropha podagrica Hook. Common Names Buddha Belly Plant, Buddha Belly, Bottleplant Shrub, Bottle Euphorbia, Purgingnut, Gout Plant, Gout Stick, Purging Nut, Guatemalan Rhubarb, Guatemala Rhubarb, White Rhubarb, Goutystalk Nettlespurge, Tartogo
Scientific Classification Family: Euphorbiaceae Subfamily: Crotonoideae Tribe: Jatropheae Genus: Jatropha
Description Jatropha podagrica is a tropical, frost-sensitive, succulent shrub, up to 8 feet (2.4 m) tall (usually up to 3 feet / 90 cm). It has a swollen and knobby, grey-skinned stem (large bottle-like caudex) and green, smooth, waxy leaves, up 12 inches (30 cm) in diameter. The flowers are small, coral-like and bright red in color.
How to Grow and Care The key to growing successful Jatropha is to achieve the proper balance between moisture and drainage. They typically appreciate a steady supply of water, but the most popular species cannot tolerate being submerged or soaked and will quickly succumb to root rot. Many of the popular Jatropha species make excellent small trees for a conservatory or sunny corner. Keep them well pruned so they don’t outgrow their space too soon. Jatropha are vulnerable to pests including aphids, mealy bugs, scale, and white fly. If possible, identify the infestation as early as possible and treat with the leave toxic option. Jatropha can be propagated by seed (if you’re fortunate enough to get sides) or by stem cuttings. To take stem cuttings, remove a small piece of stem, dip it in rooting hormone, then pot into a small pot with seedling starter soil.

Scientific Name Hatiora salicornioides (Haw.) Britton & Rose Common Names Dancing Bones, Dancing Bones Cactus, Drunkard’s Dream, Spice Cactus, Bottle Cactus
Synonyms Rhipsalis salicornioides (basionym) Scientific Classification Family: Cactaceae Subfamily: Cactoideae Tribe: Rhipsalideae Genus: Hatiora
Description Hatiora salicornioides is a slender, erect, arching or somewhat pendent, bushy, cactus, up to 2 feet (60 cm) tall. A stem consists of smaller segments, up to 1.2 inches (3 cm) long. The flowers are small, bell-shaped, orange yellow in color, up to 0.8 inch (2 cm) long and in diameter.
How to Grow and Care Hatiora thrives best in indirect light with exposure to morning and evening sun. Hatioras prefers spring, summer, and fall temperatures around 75-80 °F (24-27 °C). Winter temperatures should be between 45-65 °F (7-18 °C) only. It prefers a well drained soil. Cactus or epiphytic compost works well. It can be propagated easily through cuttings that can root immediately in soil. Hatiora likes long nights of about 14 hours. Cover the plant with a paper bag to shut out sunlight. Try not to reposition the plant once flower buds appear, as these could fall off during any movement. It needs a month’s rest after flowering, so water sparingly during this period. Hatioras prefers fertilization every 14 days. Use a balanced 10-10-10 fertilizer, and dilute to half strength.
