[ Mangave (Agave 'Bad Hair Day') | Posted on February 9, 2023 ] Hybrid agave with many arching, spotted leaves. Said to be a hybrid of the former Manfreda maculosa (now Agave maculata, a spotted plant) and Agave geminiflora, a toothless agave with many narrow, weak leaves. The patent mentions similarities to the agave hybrid 'Man of Steel' (a cross of 'Bloodspot' x Agave stricta); this plant is much more glaucous. 'Bad Hair Day' may not have as many or as intense spots in lower light situations (strong light is best for full realization of the purple spots). The whole plant may appear more purplish than green when moderately stressed. |
[ Sedum (Sedum sinforosanum) | Posted on January 17, 2023 ] Small, offsetting, glaucous rosette succulent. with rosettes to about 5 inches and stems to about 2-3 inches long. Leaves are bluish pink to whitish and flowers are fragrant and bright white, with recurved petals. |
[ Aeonium (Aeonium haworthii 'Dream Color') | Posted on January 17, 2023 ] Branchy, bushy Aeonium with smallish rosettes bearing varying degrees of marginal variegation (green in the center, yellowish around the edges, reddish margins). Young leaves appear to be much more variegated. Prone to reversion to an all-green form. Very common and well behaved in cultivation. |
[ Pachyphytum werdermannii | Posted on January 7, 2023 ] Glaucous whitish, greenish, bluish or pinkish leaf succulent with oblong leaves and reddish flowers hidden by large bracts (color most visible looking head-on). Stems grow to about 8 inches tall and may hang downward to about 3 feet in old age. They may branch freely at the base. |
[ Zapotitlan Barrel Cactus (Parrycactus flavovirens) | Posted on December 27, 2022 ] Clumping barrel cactus from the Valley of Tehuacán with reddish flowers. May grow to form low mounds several feet wide in old age in habitat, though probably not in cultivation in your lifetime. 13 acute ribs, 4-6 central spines (variable length to 3"), 12-20 radial spines (sometimes more like bristles). |
[ MacDougall's Giant Century Plant (Furcraea macdougalii) | Posted on December 23, 2022 ] Large, single-stemmed, tree-sized rosette succulent to 20 feet tall or more. Green, rough, reflexed leaves grow up to 7 feet long. The inflorescence may double the height of the plant, with whitish, hanging flowers. |
[ Green Coral Plant (Euphorbia flanaganii 'Arm Crest') | Posted on December 23, 2022 ] One of two different crested forms of this species, and orders of magnitude more common in cultivation than a head crest. This form is a crested version of one of the narrow branches of this species (propagated easily from cuttings). A head crest is a crested version of the much wider main stem (and a very rare chance occurrence among seedlings). |
[ Century Plant (Agave rzedowskiana) | Posted on December 23, 2022 ] Smallish porcupine agave (rosettes usually 10-18 inches) from the same group as striata and stricta. Many narrow green, bluish green, or gray leaves at maturity. Leaves are wider than striata or stricta (except striata var. falcata) but the overall habit and polycarpic lifestyle are quite similar. Found in the western Mexican states of Sinaloa and Jalisco at 1600-1700m altitude in the Sierra Madre Occidental. |
[ Fouquieria (Fouquieria formosa) | Posted on December 11, 2022 ] Small spiny tree from central to southern Mexico with peeling yellowish bark and red or orange-yellow flowers. Spines may vary greatly in size (and some plants may appear to be spineless). From a summer rainfall area. Flowering may occur in fall or winter (or at any time). |
[ Maguey Pichomel (Agave marmorata) | Posted on December 9, 2022 ] Beautiful glaucous agave from the Valley of Tehuacán, often with marked crossbanding. Leaves are rough, channeled and often wavy, ranging from bluish gray to light green. Rosettes are typically lax and open. In habitat even plants in the shade of bushes are really bright and powdery. Leaf margins are mammillate and toothy. |
[ Cardon Blanco (Cephalocereus columna-trajani) | Posted on December 9, 2022 ] Large unbranched columnar cactus with furry spines, to about 30 feet tall. The flowers appear on a pseudocephalium near the top (only), usually facing north. The top of mature, reproductive plants leans slightly in this direction. |
[ Tetetzo (Cephalocereus tetetzo) | Posted on December 8, 2022 ] Extra large columnar cactus from Puebla and Oaxaca in southern Mexico, with branching gray-green stems and whitish nocturnal flowers. 15-20 ribs, usually 1 central spine, 8-13 radial spines. May reach up to about 50 feet tall. Dominant at lower altitudes in the valley of Tehuacán, replaced by Cephalocereus columna-trajani in some locations at higher altitudes. Hybrids with this Cephalocereus are known to exist. The buds of this plant (called tetechas) are edible and delicious. |
[ Poinsettia (Euphorbia pulcherrima) | Posted on November 27, 2022 ] The poinsettia is probably the most common Euphorbia in cultivation, appearing on the potted plant market in late fall with big red bracts, which look like flowers although they are just the leafy part of the reproductive structure. Unlike a few other Euphorbias, which pose actual hazards to the gardener in the form of their sap (which can be an extreme irritant), the poinsettia seems to be pretty harmless. Thus its popularity and its general safety (though avoid the sap to be sure). |
[ Biznaga de Nejapa (Mammillaria karwinskiana subsp. nejapensis) | Posted on November 26, 2022 ] This subspecies of karwinskiana often branches dichotomously and may become multiheaded over time. Like the others, it has reddish radial spines turning grayish white as they age. These spines may be highly variable in length. |
[ Gasteraloe (XGasteraloe 'Twilight Zone') | Posted on November 19, 2022 ] Dark green to brown rosette succulent with fine raised whitish bumps on the leaves. Mostly solitary, though it may branch by division of the growth center or by axillary branching (sometimes triggered by damage to the growth center). Easy to start from cuttings when available. |
[ Monadenium (Euphorbia ritchiei) | Posted on November 17, 2022 ] Clumping succulent with knobby, sausage-like stems and delightful hooded pink cyathia, which appear in abundance near the tips of stems at maturity. From East Africa. Somewhat variable, especially in terms of the size/shape and persistence of leaves (which are generally short lived). My plant was mostly leafless. Variegated forms exist. Branches may appear near the base and/or higher up. Final size pot in the range of 6-8 inches. Relatively common in cultivation (one of the best represented members of the former genus Monadenium, now lumped with Euphorbia, characterized by having hooded cyathia). |
[ Pachyveria (XPachyveria 'Little Jewel') | Posted on November 10, 2022 ] Striking blue succulent with smallish rosettes in clusters. Very ornamental, especially when grown under strong light to increase the glaucous glow and keep the form compact. Leaves tend to have a sort of faceted appearance when viewed up close, thus the cultivar name. |
[ Toyon (Heteromeles arbutifolia) | Posted on November 9, 2022 ] Large bushy shrub or tree from California and northwestern Baja California, usually found with coastal chaparral but also less frequently inland. Notable for its bright red holly-like fruit, produced in fall, which are a real highlight. Flowers are white and appear in clusters at the end of stems. |
[ Peruvian Old Man Cactus (Espostoa lanata) | Posted on November 7, 2022 ] Wooly, tree-like columnar cactus to 5-23 feet tall, with branching above about 3-4 feet. Stems grow to 4 inches wide (trunks to 8 inches wide) with 18-25 ribs, 0-1 central spine, 30-40 radial spines. Purplish flowers appear on a lateral cephalium (4-5 ribs) with light brown or grayish wool. From southern Ecuador and northern Peru, widespread and variable. The type species of this genus of spiny, columnar cacti with lateral cephalia, and probably the most common in cultivation. |
[ Tufted Agave (Agave albopilosa) | Posted on November 6, 2022 ] Small, very ornamental agave with straight leaves bearing tufts of hair at the end when mature (the basis for the name). Described in 2007, from a limited area of the Sierra Madre Oriental (1000-1500m) of northeastern Mexico. Shares territory with A. bracteosa, lecheguilla, striata. From the same group as striata, with an unbranched inflorescence. |
