Scientific Name Senecio barbertonicus Klatt Common Names Succulent Bush Senecio, Barberton Senecio, Barberton Groundsel
Scientific Classification Family: Aizoaceae Subfamily: Asteroideae Tribe: Senecioneae Subtribe: Senecioninae Genus: Senecio
Description Senecio barbertonicus is an evergreen succulent bush, up to 6 feet (2 m) tall and wide, with a fleshy, cylindrical, finger-like, light green leaves that point upwards along the branches and are crowded toward stem tips, up to 4 inches (10 cm) long and 0.4 inch (1 cm) in diameter. The flowers are yellow, up to 3 inches (7.6 cm) long and 0.4 inch (1 cm) in diameter.
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 Acanthocereus tetragonus (L.) Hummelinck Common Names Barbed Wire Cactus, Sword Pear, Triangle Cactus, Dildo Cactus, Night-Blooming Cereus
Synonyms Cactus tetragonus (basionym), Cereus tetragonus, Acanthocereus pentagonus, Acanthocereus pitajaya, Cactus pitajaya, Cereus pitajaya, Cactus pentagonus, Cereus pentagonus, Cereus pentagonus, Cactus pentagonus, Cereus acutangulus, Acanthocereus acutangulus, Cereus princeps, Acanthocereus princeps, Cereus princeps, Cereus variabilis, Acanthocereus floridanus, Acanthocereus colombianus, Cactus prismaticus, Cereus prismaticus, Cactus reptans, Cereus reptans
Scientific Classification Family: Cactaceae Subfamily: Cactoideae Tribe: Echinocereeae Genus: Acanthocereus
Description Acanthocereus tetragonus is a tall, columnar cactus, up to 23 feet (7 m) tall. The stems are dark green with 3 – 4 (5) angles and up to 3 inches (8 cm) in diameter. Areoles are grey, up to 1.2 inches (3 cm) from each other. Central areoles have 1 – 2 (3) spines up to 1.6 inches (4 cm) long. Radial areoles have 6 – 8 (10) spines up to 1 inch (2.5 cm) long. The flowers are up to 8 inches (20 cm) in diameter with a tube, up to 6 inches (15 cm) in length. Outer tepals are greenish-white, inner tepals are pure white, and pistils are creamy white. The shiny, red fruits are up to 2 inches (5 cm) long.
Hardiness USDA hardiness zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C). 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.

Scientific Name Opuntia ficus-indica (L.) Mill.
Common Names Indian Fig Opuntia, Indian Fig, Barbary Fig, Cactus Pear, Spineless Cactus, Prickly Pear, Mission Cactus, Mission Prickly Pear, Smooth Mountain Prickly Pear, Smooth Prickly Pear, Sweet Prickly Pear, Tuberous Prickly Pear, Tuna Cactus
Synonyms Cactus ficus-indica (basionym), Cactus decumanus, Opuntia amyclaea, Opuntia cordobensis, Opuntia decumana, Opuntia ficus-barbarica, Opuntia gymnocarpa, Opuntia hispanica, Opuntia joconostle, Opuntia maxima, Opuntia megacantha, Opuntia paraguayensis Scientific Classification Family: Cactaceae Subfamily: Opuntioideae Tribe: Opuntieae Genus: Opuntia
Description Opuntia ficus-indica is a slow growing perennial shrub up to 16.5 feet (5 m) high. The root-system spreads horizontally. Stems (cladodes) are very thick, succulent, oblong to spatulate, up to 2 feet (60 cm) long and up to 10 inches (25 cm) wide. The epidermis is very thick and waxy, thus very water repellent and sun reflecting. Flowering occurs on 1-2 year-old cladodes. Flowers open in the late morning. The fruit is succulent, reddish, ellipsoid, up to 3 inches (7.5 cm) long and edible.
How to Grow and Care Though the large variety of species within the Opuntia genus means different types of prickly pears may need slightly different care, all are desert cacti that need lots of sun, lots of light, and very little water. If you live in a hot, arid area – particularly the American Southwest – these plants can generally be planted outside, left alone, and enjoyed. Though Opuntia will grow just fine in a garden, they can be grown in pots as well. To repot, ensure the soil is dry, then remove the pot and knock away the old soil. After treating any cuts with fungicide, place the prickly pear in a new pot and backfill it with potting soil.
Uses Opuntia ficus-indica is a species of cactus that has long been a domesticated crop plant important in agricultural economies throughout arid and semiarid parts of the world. It is grown primarily as a fruit crop, but also for the vegetable nopales and other uses. Most culinary references to the “Prickly Pear” are referring to this species.

Scientific Name Pereskia aculeata Mill. Common Names Barbados Gooseberry, Barbados Shrub, Leaf Cactus, Ora-Pro-Nobis
Synonyms Cactus lucidus, Cactus pereskia, Pereskia foetens, Pereskia fragrans, Pereskia godseffiana, Pereskia longispina, Pereskia pereskia, Pereskia rubescens, Pereskia undulata Scientific Classification Family: Cactaceae Subfamily: Pereskioideae Genus: Pereskia
Description Pereskia aculeata is a scrambling vine growing up to 33 feet (10 m) tall in trees, with stems up to 1.2 inches (3 cm) thick. Younger stems have hooked thorns and older stems have clusters of woody spines. The leaves are up to 4 inches (10 cm) long and up to 1.6 inches (4 cm) wide, simple, entire, and deciduous in the dry season. The strongly scented flowers are white, cream or pinkish, up to 2 inches (5 cm) in diameter, and numerous, produced in panicles. The fruit is a rounded berry, translucent white to pink, yellow, orange or red, and up to 0.8 inch (2 cm) in diameter.
How to Grow and Care As with many cacti, Pereskias can be almost ignored and still flourish. One of the major advantages that succulents pose as houseplants is their ease, and overwatering or overfeeding them is a bigger danger than neglecting them because it can damage their roots. If you repot them, remember to leave them alone for a brief period so as to avoid overstressing them, and make sure to keep an eye out for common houseplant pests.

Scientific Name Crassula barklyi N.E.Br. Common Names Rattlesnake Tail, Bandaged Finger
Synonyms Crassula teres Scientific Classification Family: Crassulaceae Subfamily: Crassuloideae Genus: Crassula
Description Crassula barklyi is a perennial, dwarf succulent shrub with erect or rarely decumbent stems. It branches at the base into several attractive finger-like growths. It is very slow growing but will reach up to 4 inches (10 cm). The stem is covered neatly and smoothly by the overlapping leaves to form a short almost cylindrical column, which has something of the appearance of a tree cone. Younger branches are almost spherical and looks like grey-green rosebuds. The leaves are fleshy, depressed-ovate, concave, up to 0.2 inch (5 mm) long and up to 0.6 inch (15 mm) wide. It flowers in winter. Flowers are tiny, stemless and white in color.
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.

Synonyms Senecio radicans, Cacalia radicans (basionym), Kleinia radicans Scientific Classification Family: Asteraceae Subfamily: Asteroideae Tribe: Senecioneae Subtribe: Senecioninae Genus: Curio
Description Curio radicans is a fast-growing succulent with vines that can reach at least 3 feet (90 cm) long. The small, up to 1.2 inches (3 cm) long, green, pointed leaves grow single-file along the cascading stems, with the sides of the leaves partly translucent, allowing sunlight to shine through. The flowers are small, cinnamon-scented and white in color.
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.

Scientific Name Sedum rubrotinctum R.T.Clausen It has also been classified as a hybrid plant of Sedum pachyphyllum and Sedum stahlii, named Sedum × rubrotinctum.
Common Names Jelly Bean Plant, Jelly Bean, Pork and Beans, Brown Beans, Christmas Cheer, Banana Cactus Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Sedum
Description Sedum rubrotinctum is an evergreen, succulent perennial with sprawling, leaning stems, up to 8 inches (20 cm) tall. The leaves are jelly bean shaped, 0.75 inch (1.9 cm) long, green with red-brown tips which turn to bronze in the summer months. The flowers are small, star-shaped and yellow in color.
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 Sedum 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 ingens Rose Common Names Baja Live Forever Synonyms Dudleya eximia, Dudleya viridicata, Echeveria ingens
Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Dudleya
Description Dudleya ingens is a rosette-forming succulent with usually solitary rosettes up to 10 inches (25 cm) wide, with many lance-shaped, green leaves with red spots that radiate out and slightly up. In spring to early summer appear the red stems bearing pale yellow blushed-pink flowers.
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 Fenestraria rhopalophylla (Schltr. & Diels) N. E. Br. Common Names Baby Toes, Baby’s Toes, Window Plant Scientific Classification Family: Aizoaceae Subfamily: Ruschioideae Tribe: Ruschieae Genus: Fenestraria
Description Fenestraria rhopalophylla is an evergreen, perennial succulent, up to 6 inches (15 cm) tall. Not present or very reduced stem. The tip of each leaf is transparent, and diffuse the light to the rest of the leaf. The roots are thick, shallow, and spreading. The leaves are glaucous green, smooth, up to 1.5 inches (4 cm) long and with a convex apex. Medium-large up to 1.2 inch (3 cm) in diametar, pure white, solitary or in groups of up to three flowers borne on long pedicels.
Hardiness USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C). How to Grow and Care Fenestraria prefer sandy soil and should be watered sparingly at all times to avoid root rot and split leaves. They need to be kept somewhat dry in the summer. Mix equals parts potting soil with pumice or perlite. Outdoors, grow in full to part sun; indoors, provide bright indirect light. Water thoroughly when soil is dry to the touch. Fenestrarias are somewhat frost tolerant, but protection is advisable to prevent scarring.
They are usually propagated by seed but sometimes by cuttings. Like many succulents, Fenestrarias produces offsets as the clusters of leaves mature and spread. These are easy to divide from the main clump and will readily produce another plant.

Scientific Name Frithia pulchra N.E.Br.
Common Names Window Plants, Baby Toes, Fairy Elephant’s Feet, Transvaal Fairy Elephant’s Feet Scientific Classification Family: Aizoaceae Subfamily: Ruschioideae Tribe: Ruschieae Genus: Frithia
Description Frithia pulchra is a dwarf rosette forming perennial succulent up to 1.2 inches (3 cm) in diameter, that grows almost completely embedded in the ground. Almost stemless or with a much reduced stem. Similar looking to the Fenestraria rhopalophylla, but its leaves are more tubular and the flowers are pink. Club shaped leaves, up to 0.8 inch (2 cm) long and up to 0.2 inch (5 mm) in diameter, often partially buried, grey-green, arranged in a cluster, flattened or rounded and transparent at the tips. Quite robust fruits, spongy capsules resembling a barrel, up to 0.2 inch (5 mm) in diameter and 0.25 inch (7 mm) long.
Hardiness USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C). How to Grow and Care Frithia is a summer grower and relatively easy to cultivate. It need light sporadic watering during its winter resting period and requires moderate sprinkling in summer as it is rot prone if kept too moist when the heat turns off its growth cycle. Gritty, well drained soil, containing a small amount of organic material will keep this species happy.
Frithia can be grown in pots or out of doors in a rockery. Soak the compost fully but allow it to dry out perfectly between waterings. Under-watering can lead to disastrous results, so be generous with water in summer. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid.
