Scientific Name Aloe humilis (L.) Mill. Common Names Spider Aloe, Blue Dwarf Aloe, Dwarf Hedgehog Aloe
Synonyms Aloe echinata, Aloe incurva, Aloe macilenta, Aloe perfoliata var. humilis, Aloe suberecta, Aloe subtuberculata, Aloe tuberculata, Aloe verrucosospinosa, Aloe virens, Catevala humilis, Haworthia ferox Scientific Classification Family: Xanthorrhoeaceae Subfamily: Asphodeloideae Genus: Aloe
Description Aloe humilis is a low growing succulent that forms dense clusters of small up to 8 inch (20 cm) wide stemless (or very shortly stemmed) rosettes. The leaves are up to 5 inches (12.5 cm) long and 0.7 inch (1,8 cm) wide, pale blue-green or grey-green, incurved triangular-shaped (20-30 per rosette). They have long soft white marginal spines up to 0.1 inch (3 mm) long and a gray-green waxy surface covered with irregularly spaced bumps. The unbranched up to 1.1 feet (35 cm) tall flower spikes bearing about 20 pendulous up to 2 inches (5 cm) long bright red-orange flowers.
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.
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 cylindricus (A.Berger) Jacobsen Common Names Narrow-Leaf Chalk Sticks, Blue Chalk Fingers Synonyms Senecio vitalis, Senecio talinoides subsp. cylindricus
Scientific Classification Family: Asteraceae Subfamily: Asteroideae Tribe: Senecioneae Subtribe: Senecioninae Genus: Senecio
Description Senecio cylindricus is a low growing succulent shrub up to 24 inches (60 cm) tall and spreading up to 5 feet (1.5 m) wide with semi-prostrate stems that turn upright and are crowded at the tips with up to 5 inches (12.5 cm) long, slender and slightly upcurved, gray-green, tubular leaves. The small, rayless, dull cream colored flowers appear in corymbs in late spring to early summer.
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 Agave tequilana F. A. C. Weber Common Names Blue Agave, Tequila Agave
Synonyms Agave angustifolia subsp. tequilana, Agave palmaris, Agave palmeris, Agave pedrosana, Agave pes-mulae, Agave pseudotequilana Scientific Classification Family: Asparagaceae Subfamily: Agavoideae Genus: Agave
Description Agave tequilana is a fast growing plant that grows up to 5 feet (1.5 m) tall and wide, with up to 4 foot (1.2 m) long narrow leaves of a beautiful shade of blue gray with a brown sharp terminal spine and margin teeth. The mature plants sprout a shoot when about five years old which grows into a stem up to 15 feet (4.5 m) tall and topped with yellow flowers.
How to Grow and Care Agave is not a difficult plant to grow. They’re slow-growing and dramatic and will even thrive on a bit of neglect. If you’re the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. If, however, you’re the type of person who likes to set it and forget it, and you have a sunny window, Agave might the way to go. Be aware that some of the large varieties will eventually outgrow your room (unless you have a large greenhouse), and Agave can be aggressive.
Uses Man has been harvesting and utilizing Agaves for approximately 9,000 years. The huge plant comprised a huge part of primitive man’s diet. Closely related to lilies there are three major parts which are edible: flowers, stalks or basal rosettes, and the sap.

Scientific Name Kalanchoe prolifera (Bow.) R.-Hamet
Common Names Blooming Boxes Synonyms Bryophyllum proliferum Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Kalanchoeae Genus: Kalanchoe
Description Kalanchoe prolifera is a fast growing and interesting succulent plant with up to 6 feet (1.8 m) tall, typically unbranched stems holding foot (30 cm) long pinnately compound succulent green leaves in opposite pairs that have reddish purple colored petioles and leaf margins when grown in bright light. As the leaves drop the stem has interesting leaf scar bands along the thick stem, which as the plant matures after several years, is topped with 3 foot (90 cm) tall panicle of greenish orange flowers in late winter – the green calyces of the flower are box shaped and nearly hide the pale orange petals. The plant declines after flowering but many new plantlets form in the inflorescence and the main plant will often sucker up with a new stem so a colony is easy to establish.
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 Opuntia microdasys subsp. rufida (Engelm.) U. Guzmán & Mandujano. Common Names Blind Prickly Pear, Blind Pear, Cow Blinder, Cinnamon Cactus, Clock Face Cactus, Cactus Red Bunny Ears, Cinnamon Pear, Cinnamon Bunny Ears
Synonyms Opuntia rufida (Basionym), Opuntia herrfeldtii, Opuntia lubrica, Opuntia microdasys var. rufida, Ountia rufida var. tortiflora Scientific Classification Family: Cactaceae Subfamily: Opuntioideae Tribe: Opuntieae Genus: Opuntia
Description Opuntia microdasys subsp. rufida is an upright and spreading, much branched cactus, up to 5 feet (1.5 m) tall. Stems are jointed into fleshy, rounded pads that are various in color, from lucid purple when young to glacous blue with age. Glochids densely arrayed, greyish to reddish brown, rarely with spines. The flowers are yellow to bright orange-red and about 3 inches (7.5 cm) across. The fruit is rounded, fleshy, with very short spines, yellow-green ripening to red and 1 inch (2.5 cm) long.
Hardiness USDA hardiness zone 9a to 10b: from 20 °F (−6.7 °C) to 40 °F (+4.4 °C). 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.
Prickly pears can propagate either by cuttings or by seed. To propagate by cuttings, sever pads from a plant and let them dry so that the wounds heal. Then place the plants in a dry soil and refrain from watering them until they begin to grow to avoid rotting them.

Scientific Name Echeveria ‘Black Prince’ Common Names Black Hens and Chicks Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Echeveria
Description Echeveria ‘Black Prince’ is a slow and low growing succulent plant. It produces clumps of short rosettes up to 3 inches (7.5 cm) wide with thin dark triangular, blackish leaves. These leaves first emerge greenish but darken to a deep lavender brown and with age the lower leaves widen out to as much as 1 inch (2.5 cm) at the base with an acuminate tip that has fine yellow edges. The dark red flowers appear on short stalks in late fall to early winter.
How to Grow and Care Most of the common Echeveria species are not complicated succulents to grow, provided you follow a few basic rules. First, be careful never to let water sit in the rosette as it can cause rot or fungal diseases that will kill the plant. Additionally, remove dead leaves from the bottom of the plant as it grows. These dead leaves provide a haven for pests, and Echeveria are susceptible to mealy bugs. As with all succulents, careful watering habits and plenty of light will help ensure success.
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 Haworthia nigra (Haw.) Baker Common Names Black Haworthia Synonyms Haworthia nigra var. nigra, Aloe nigra, Apicra nigra, Catevala nigra, Haworthia venosa subsp. nigra, Haworthia ryneveldii, Haworthia schmidtiana
Scientific Classification Family: Xanthorrhoeaceae Subfamily: Asphodeloideae Genus: Haworthia
Description Haworthia nigra is a slow-growing, erect succulent with deep greenish-black leaves, up to 4 inches (10 cm) tall. The pointy, partially folded, stiff leaves emerge from the center of the rosette. Outer and inner leaf sides have ridged, gray bumps called tubercles. Each new leathery leaf emerges from the center atop the one below it, which lends plants a stacked or tiered look. In winter’s chill or under excessive drought stress plants blush red. Overall, the foliage remains dark green with varying grades of gray to black. In late spring or summer, mature rosettes produce single, upright, wiry flower stems topped with tiny white flowers.
How to Grow and Care Haworthia are not considered difficult houseplants to grow—if you can keep a pot of aloe alive on a windowsill, chances are you can do the same with a dish of Haworthia. As with all succulents, the most dangerous situation is too much water—they should never be allowed to sit in water under any circumstances. At the same time, these decorative little plants can be grown in interesting containers such as tea cups and even miniature baby shoes. If you’re given a Haworthia in such a container, make sure the container had adequate drainage. If it doesn’t, it might be a good idea to pop the plant out of its container and add a layer of gravel to the bottom to reduce the wicking action of the soil above. Finally, look out for sunburned spots on your plants.
Haworthia are small (usually remaining between 3 inches (7.5 cm) and 5 (12.5 cm) inches in height) 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 Echeveria affinis E. Walther Common Names Black Echeveria Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Echeveria
Description Echeveria affinis is evergreen, low-growing, perennial succulent, up to 8 inches (20 cm) tall and wide. The levaes are fleshy, olive-brownish, up to 2 inches (5 cm) long and up to 0.8 inch (2 cm) wide, formed on rosettes. The red star-shaped flowers sprout on a stem during the summer.
How to Grow and Care Most of the common Echeveria species are not complicated succulents to grow, provided you follow a few basic rules. First, be careful never to let water sit in the rosette as it can cause rot or fungal diseases that will kill the plant. Additionally, remove dead leaves from the bottom of the plant as it grows.

Scientific Name Stapelia leendertziae N.E. Br. Common Names Black Bells, Maroon Cup Starfish, Rugose Cup Starfish, Star Flower, Carrion Flower
Synonyms Stapelia wilmaniae Scientific Classification Family: Apocynaceae Subfamily: Asclepiadoideae Tribe: Stapeliae Genus: Stapelia
Description Stapelia leendertziae is a succulent plant with long, erect, angular stems and dull green to reddish in color. It is most conspicuous when in flower owing to the unique large, bell-shaped, deep reddish to dark purple flowers that are up to 5 inches (12.5 cm) long.
How to Grow and Care Several species are fairly easy to grow. Others, often those with slightly hairy stems and the more unusual flowers, are more challenging and require careful watering (with some fertiliser) during the growing season and complete withdrawal of water during the winter months. A minimum winter temperature of 10°C (50°CF) is acceptable, providing that plants are kept absolutely dry. A heated growing bench or incubator may help delicate plants to get throught the colder months. However, many species live under shrubs in habitat and prefer light shade rather than full sun. A gritty compost is essential, and clay pots are advisable for the more delicate species. Some growers prefer a mineral-only compost to minimize the chance of fungal attack on the roots. A layer of grit on the surface of the compost prevents moisture from accumulating around the base of the stems.
Keeping Stapelias and their roots free of pests such as mealy bugs is the real key to success as fungal attack often occurs as a result of damage to stems by insects.
