Scientific Name Aloe ferox Mill. Common Names Bitter Aloe, Cape Aloe, Red Aloe, Tap Aloe, Bitteraalwyn (Afrikaans), Kaapse Aalwyn (Afrikaans), Kapaloe (Swedish)
Synonyms Aloe galpinii, Aloe horrida, Aloe muricata, Aloe perfoliata var. ferox, Aloe pseudoferox, Aloe subferox, Aloe supralaevis, Pachidendron ferox, Pachidendron pseudoferox, Pachidendron supralaeve Scientific Classification Family: Xanthorrhoeaceae Subfamily: Asphodeloideae Genus: Aloe
Description Aloe ferox can grow up to 10 feet (3 m) in height with leaves arranged in rosettes. The leaves are thick and fleshy, dull green, sometimes with a slightly blue look to them, and have reddish-brown spines on the margins with smaller spines on the upper and lower surfaces. The flowers are carried in a large candelabra-like flower-head and stand up to 4 feet (1.2 m) above the leaves. There are usually between five and eight branches, each carrying a spike-like head of many flowers. Flower colour varies from orange to bright red.
How to Grow and Care Aloe is a very forgiving plant, and a well-grown Aloe can be quite beautiful. As with all succulents, it’s essential that Aloe is never allowed to sit in stagnant water, and the plant should be carefully monitored to watch for signs of overwatering. Prefers warmer temperatures of 70ºF/21ºC to 80ºF/27ºC, but will survive down to 40ºF/4.5ºC. Aloe are not particularly fast-growing and will only rarely need repotting. Repot plants in the spring that are tipping over their pots or have ceased growing.

Scientific Name Jasminocereus thouarsii (F. A. C. Weber) Backeb. Common Names Candelabra Cactus Synonyms Cereus thouarsii, (basionym), Jasminocereus thouarsii var. thouarsii, Jasminocereus howellii, Cereus sclerocarpus, Brachycereus thouarsii, Cereus galapagensis, Jasminocereus galapagensis, Jasminocereus sclerocarpus
Scientific Classification Family: Cactaceae Subfamily: Cactoideae Tribe: Browningieae Genus: Jasminocereus
Description Jasminocereus thouarsii is a columnar cactus that can grow up to 16.4 feet (5 m) tall. It has tree-like form with a thick stem that usually separates into several branches. The stem is deeply ridged and bears clusters of long spines which may be colored white, yellow, reddish-brown or black. The scientific name is a reference to its attractive large jasmine-like flowers which have white and yellow petals. The plum-sized fruits grow on the trunks and bright red when ripe.
How to Grow and Care Like most cacti, Cereus are fairly low-maintenance and hardy. Make sure they receive enough water without becoming waterlogged, especially during the summer, and fertilize them for best results. If the roots have become black or overly soft, the cactus could be experiencing root rot – cut away the affected parts and replant. Like all cacti, give them lots of direct sunlight, especially during the summer. Well-drained soil is best, and most Cereus perform well in a soil that contains some organic material. Some recommend avoiding a soil that contains sphagnum moss, though – it can make the cactus vulnerable to root rot.
Cereus cacti propagate quite easily from cuttings; simply sever a branch and replant in moist, well-drained soil. It helps to allow the cut end dry out and harden before you replant it; this makes it easier for the new cactus to form roots.

Scientific Name Euphorbia lactea Haw. Common Names Mottled Spurge, Frilled Fan, Elkhorn, Dragon Bones Tree, Dragon Bones, Candelabra Spurge, Candelabra Cactus, Caper Spurge, Candle Stick Tree, False Cactus, Hat Rack Cactus, Marmoreuforbia (Swedish)
Scientific Classification Family: Euphorbiaceae Subfamily: Euphorbioideae Tribe: Euphorbieae Subtribe: Euphorbiinae Genus: Euphorbia
Description Euphorbia lactea is a tall, dark-green, many-branched, spinous milky-juiced shrub, up to 16.4 feet (5 m) tall. Stems are erect, up to 2 inches (5 cm) in diameter, ridged, with a triangular or rhombic cross-section and constricted into oblong green segments. Centre of the segments are conspicuously pale often with very ornamental whitish and lime green marbled marking. The ridges are spiny, with short spines up to 0.2 inch (5 mm) long. The leaves are rudimentary, reddish, up to 0.12 inch (3 mm) in diameter and soon deciduous.
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.

Scientific Name Aloe arborescens Mill. Common Names Torch Aloe, Torch Plant, Candelabra Aloe, Octopus Plant, Tree Aloe, Mountain Bush Aloe, Krantz Aloe Synonyms Aloe perfoliata var. arborescens, Aloe perfoliata var. eta, Aloe natalensis, Aloe fruticosa, Aloe frutescens, Aloe arborea, Catevala arborescens, Aloe candelabra, Aloe milleri, Aloe natalensis, Aloe viridifolia
Scientific Classification Family: Xanthorrhoeaceae Subfamily: Asphodeloideae Genus: Aloe
Description Aloe arborescens is a large multi-headed sprawling succulent, up to 10 feet (3 m) tall with many up to 18 inches (45 cm) wide rosettes of narrow, soft-toothed, margined, dull green, yellowish or sometimes blue-green leaves. Deep orange, almost red (there are also pure yellow forms) flowers hang tightly on unbranched inflorescence that rises up to 2 feet (60 cm) above the foliage.
Hardiness USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C). How to Grow and Care Aloe is a very forgiving plant, and a well-grown plant can be quite beautiful. As with all succulents, it’s essential that Aloe is never allowed to sit in stagnant water, and the plant should be carefully monitored to watch for signs of overwatering. Prefers warmer temperatures of 70ºF/21ºC to 80ºF/27ºC, but will survive down to 40ºF/4.5ºC. Feed with a cactus fertilizer in the summer only. Suspend feeding in the winter as the plant goes dormant.
Aloe are not particularly fast-growing and will only rarely need repotting. Repot plants in the spring that are tipping over their pots or have ceased growing. Use a fast-draining potting mix with one-third sand or pebbles.

Scientific Name Senecio angulatus L. f. Common Names Climbing Groundsel, Creeping Groundsel, Cape Ivy, Garden Senecio, Mile-a-Minute, Scrambling Groundsel, Vining Senecio, Canary Creeper
Synonyms Senecio macropodus, Cineraria laevis Scientific Classification Family: Aizoaceae Subfamily: Asteroideae Tribe: Senecioneae Subtribe: Senecioninae Genus: Senecio
Description Senecio angulatus is a scrambling or twining herb whose form is a dense tangled shrub, up to 6.6 feet (2 m) tall or a climber to 20 feet (6 m) high. Succulent, pale green stems with glossy, thick and fleshy, coarsely toothed leaves with one to three teeth each side, up to 8 inches (20 cm) long and up to 5.5 inches (14 cm) wide. Flowers are daisy-like with yellow petals produced in open clusters at the end of its branches or stems.
How to Grow and Care Established plants are extremely drought tolerant. They do need some water, during the summer, but do not leave the soil wet for prolonged periods. Allow the soil to dry out between waterings in the winter, when they are somewhat dormant. Since they are growing in sandy soil, nutrients will need to be replenished. Fertilize annually, but lightly. Too much fertilizer will cause a lot of leggy growth.
Taller varieties can get floppy. You can prune them back to where the stem is firm, in very early spring. You can even root the cuttings. Plants can be divided or repotted in early spring. If you are growing them in containers, they enjoy spending the summer outdoors. Wait until there is no danger of frost and move them back indoors in the fall.

Scientific Name Crassula capitella Thunb. Common Names Campfire Plant, Saint Andrew’s Cross Synonyms Crassula albanensis, Crassula capitellata, Crassula impressa, Crassula paniculata, Crassula rufopunctata, Crassula spicata, Crassula subbifera, Globulea impressa, Globulea paniculata, Purgosea capitellata, Purgosea spicata, Turgosea capitella
Scientific Classification Family: Crassulaceae Subfamily: Crassuloideae Genus: Crassula
Description Crassula capitella is a branching perennial succulent with fleshy propeller-like leaves that mature from bright lime green to bright red. Grows prostrate, forming mats up to 6 inches (15 cm) tall and up to 3.3 feet (1 m) wide. Blooms in clusters of white flowers, up to 0.25 inches (6 mm) in diameter.
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.

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. 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.

Scientific Name Ferocactus cylindraceus (Engelm.) Orcutt Common Names California Barrel Cactus, Cliff Barrel Cactus, Compass Barrel Cactus, Compass Cactus, Desert Barrel Cactus, Golden-Spine Barrel Cactus, Spiny Barrel Cactus
Synonyms Echinocactus acanthodes, Echinocactus viridescens var. cylindraceus Scientific Classification Family: Cactaceae Subfamily: Cactoideae Tribe: Cacteae Genus: Ferocactus
Description Ferocactus cylindraceus is usually cylindrical or spherical, with some older specimens forming columns up to 6.6 feet (2 m) in height. It is covered in long, plentiful spines, which are straight and red when new and become curved and gray as they age. The cactus bears flowers that are maroon outside, and bright yellow inside, with red or yellow centers on the side that faces the sun. The fleshy, hollow fruits are yellow.
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.

Scientific Name Adromischus maculatus (Salm-Dyck) Lem. Common Names Calico Hearts, Chocolate Drop Synonyms Adromischus mucronatus, Cotyledon alternans, Cotyledon maculata
Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Kalanchoeae Genus: Adromischus
Description Adromischus maculatus is a low growing perennials leaf-succulent, forming small clusters or mats. The stem is very short, somewhat woody, decumbent to prostrate up to 6 inches (15 cm) long. The leaves are up to 3 inches (7.5 cm) long and up to 1.4 inches (35 cm) wide, rounded, usually wedge-shaped, and with horny margin all round the leaf, green, grey-green to gray-brown, glossy sometimes almost scarlet from the sun rays and with or without dark purple spots. The young plants are often without spots. The flowers are tubular and pale yellowish green in color.
How to Grow and Care Many species are easy to grow in any free-draining gritty compost. Their compact habit allows a collection to be maintained in a small space and they grow well on any sunny window ledge or the top shelf of the greenhouse. Water mostly in spring/autumn and let them dry out between waterings. Adromischus tolerate cool, frost-free conditions during the winter if kept dry. It is as well to keep water off the foliage during the winter. Mealy bugs and vine weevils can be discouraged with a systemic insecticide. Frost hardy to 19 °F (-7 °C).
Many species can be propagated from a single leaf, which should be placed against the side of the pot so that the stem end is just touching the compost. Some species drop their leaves easily and although each leaf will form a new plant it can be a challenge to grow a large specimen.
