Gasteria batesiana is a good sized member of the genus, with a rosette of highly succulent leaves. The entire plant can exceed a foot in diameter. The leaves are up to about 2 inches wide at the leaf bases and are approximately 1/2 inch thick on my plant. Leaf color varies, and is often dependent upon light intensity and other growing conditions: leaves are typically dark green, but when grown in particularly bright light, will produce gold/bronze to brick-
Gasteria glomerata is a rather curious species, -
Gymnocalycium bruchii is native to the province of Cordoba, Argentina, where it occurs at elevations from 1600 to abut 6500 feet. It is a miniature plant, producing stems to about 1.5 inches tall and to about 2.5 inches in diameter (although the plants which I have grown tended to have smaller stems -
Haemanthus albiflos is an attractive South African species which has a wide appeal. In regions with a Mediterranean climate, it is a popular garden plant; in other regions (with hard freezes and extended cold in the winter months), it is regarded as a pot plant. It is grown for its distinctive "shaving brush" inflorescence consisting of multiple small flowers with short, narrow white petals and long white filaments topped with anthers which produce golden pollen. The flowers may be followed by fleshy berries, which will ripen to an orange to scarlet color. The bulbs grow at the surface of the ground, or half exposed. These are green and bear the leaf scars from the leaves of previous years. In time, the plants will offset, producing clumps with 10 or more bulbs. These are evergreen plants, retaining their leaves throughout the year (unlike many other bulb plants from the same region, which shed their leaves seasonally). Every year, each bulb produces only two new leaves. In my experience, the leaves from the previous year are retained until the current year's leaves are established, at which point the older leaves begin to die back; but this plant can retain leaves longer still, and bulbs may have as many as 3 pairs of leaves at once. The leaves of older, well established plants can grow to about 16 inches in length, and to about 3 inches or so in width, but on my plants, the leaves are smaller, averaging about 5 inches long and 2 to 2.5 inches wide The leaf margins bear "peach fuzz" fibers, but some populations may produce leaves which are uniformly "fuzzy" across their surfaces.
Haworthia cooperi is a fast growing, clustering species with soft, fleshy foliage (the leaves have the feel of tiny, plump grapes). The species originates from the summer rainfall areas of Sumerset East, Cape Province, South Africa. It is closely related to Haworthia cymbiformis, H. mucornata , and H. marumiana, and, according to Wikipedia, it can be distinguished from these species by "...the slight bristley "awn" on the margins of the leaves of most varieties". Another interesting trait is the presence of an extremely fine filament at the leaf tips (a trait which is barely visible in this extreme closeup – other varieties show a more prevalent filament). Variety truncata is a generally smaller plant, my plant is just over in inch across, and may possible grow to a diameter of 2 inches, with shorter foliage, and more rounded leaf tips. This is a comparatively fast growing plant, adding additional leaves to each rosette annually. While it clusters, it adds additional offsets slowly, gradually increasing its size to fill a 3 to 4 inch pot.
Haworthia glauca is widely distributed from the central to western portions of the Eastern Cape region. It typically grows fully exposed or under only slightly shaded situations on rocky slopes in habitat. Most of the plants of the species produce smooth leaves to slightly tuberculate leaves; in variety herrei, the leaves are typically more conspicuously tuberculate as can be seen in this image (this trait is not evident in my plant). The leaves are quite rigid, and end in a sharp tip, making plants of this species one of the very few of the Haworthias which can be described as “prickly”. Even without the typical ornamentation of windowed leaf tips, tubercles, etc. this is an attractive species, with glaucous grey to bluish foliage produced in tight spirals on stems which may grow to nearly 10 inches tall. Plants typically ramify from the base, producing tight cushions of many clustered stems. Habitat photos of some truly remarkable plants will give some indication of the ultimate size and spread of this plant, but be warned, I have found this plant to be a very slow grower, so the prospects of growing an equivalent plant, even under ideal greenhouse conditions, will require many years – and possibly decades of growth....
Haworthia limifolia has long been a favorite of mine. It is a more robust plant, with larger rosettes -
Haworthia reinwardtii v reinwardtii forma kaffirdiftensis is, in my opinion, one of the most elegant forms of this species, with shorter, narrower leaves, on shorter stems than most other varieties. The leaves are decorated with dense, pearl-
Haworthia truncata is one of the most unusual species of a genus which is characterized by its gems. Most species of Haworhia produce smallish rosettes of succulent leaves, each of which is typically marked with patterned windows, textured leaf surfaces, often featuring white beaded and ridged outgrowths on the dermis. Most species are highly caespitose, eventually producing dense clusters with dozens (and sometimes hundreds) of individual rosettes. Unlike virtually all other Haworthias, Haworthia truncata does not produce a rosette, but instead produces its leaves in two ranks, in a distichous arrangement, producing odd fans of tightly appressed leaves. The leaf tips end abruptly with a flat window. Plants in habitat frequently grow with their leaves buried in the soil, with only the leaf tips exposed. The windowed leaves admit light deep into the leaf tissues -
Hoya bella is a member of the Asclepiadaceae; a plant family characterized by pollinia. Pollinia, gelatinous masses containing the plant’s pollen, are only found in two plant families. The two families are asclepiads and orchids. Other asclepiads include Dischidias, Asclepias (milkweeds), Hoodias and Stapelias.
Each flower within the flower clusters of Hoya bella has five white petals surrounding a rosy pink corona. The flowers are known as pinch-
Hoya imbricata is one particularly attractive example of this last type of plant. It is an epiphytic plant with long, thin climbing stems which cling to tree trunks and branches, and bear very large succulent, plate-
Plants of Huernia aspera produce 5 to 7 angled stems, to about 1/2 inch in diameter on my plants, with succulent, fleshy stipular prickles along its ribs. The stems are initially upright, becoming more scrambling as the stems grow longer. At present, the tallest stems on my plant are about 5 inches tall, with a few longer stems growing prostrate, but I have seen plants with stems to just over 1 foot in length, and at least one online source suggests that the stems of some exceptional plants can exceed 3 feet in length. This species quickly ramifies from its base to produce a many-
Plants of Huernia zebrina produce typical 4 and 5 angled stems, with stipular prickles along its ribs. The stems can grow to about 3 or 3.5 inches in length (frequently longer in cultivation), and produce numerous branches near its base to produce an irregular tufted or spreading plant. In time, plants will spread in this manner to several feet across, although their ultimate spread can be limited by a the size of the pot, and (if necessary) by occasional pruning. Typically the stems are of a greenish coloration, but when grown outdoors in full sum, will produce stems with more ruddy tones, which will also exhibit some nicely patterned markings. It is one of the most distinctive plants of this genus, with attractively marked and oddly shaped blooms....
