[ Cabeza de Viejo (Mammillaria senilis) | Posted on September 26, 2020 ]

Low, spiny, clumping cactus from western Mexico with outstanding large (for the genus) red flowers. Stems grow to about 4 inches in diameter. Each areole has 4-6 central spines (2 of which are hooked), and dozens of radial spines. Flowers are 2-3 inches wide. From high elevations in Chihuahua, Jalisco, Sinaloa. Apparently related closely to Cochemiea. Formerly in the genus (now subgenus) Mammillopsis. There is apparently also a white-flowered form in cultivation.

[ Monadenium (Euphorbia biselegans) | Posted on September 26, 2020 ]

Spiny shrub from Tanzania with brown, shredding papery bark and deciduous leaves. The main stem and the branches tend to grow sideways or even downward with time. Old plants in nature may reach over 10 feet tall. Leaf margins are wavy and the upper surface is marked with prominent veins. The cyathia are hooded and nodding (this species was formerly known as Monadenium elegans). This plant can be propagated from cuttings, which may take up to a year to root and leaf out. It displays a striking seasonal variation between the leafless phase and the period of active growth, which begins in late summer in our cool coastal climate.

[ Desert Broom (Baccharis sarothroides) | Posted on September 24, 2020 ]

Shrub from the SW US and NW Mexico with broom-like branches and tiny compound flowers. Dioecious (separate male and female plants are required to produce seed). Extremely drought tolerant, preferring rocky or sandy soil, often one of the first plants to colonize disturbed areas. Flowers attract all sorts of winged pollinators. A bit weedy and not generally used as a garden plant, but it can be somewhat controlled through pruning. Does not tolerate wet feet. To quote Wikipedia: "Most people try to get rid of this plant". Keep a male plant if your goal is to avoid it reproducing.

[ Monadenium (Euphorbia spectabilis) | Posted on September 21, 2020 ]

Single-stemmed or occasionally branched succulent columnar Euphorbia from Tanzania, capable of growing several feet tall but rarely reaching that size in cultivation. The glaucous green stem has 5 sides, and the corners bear a continuous arrangement of reddish brown teeth or spines, each one usually branched. The leaves are keeled and they have teeth on the bottom of the midrib. They appear in summer and fall in winter, leaving scars to 1cm wide. Inflorescences appear on stout reddish deciduous peduncles that have the same sort of multicuspid teeth as the stems. The flowers are dramatic and long lasting during late fall and winter. This plant was formerly known as a Monadenium, and it has the hooded cyathia typical of that former genus. It can be readily propagated from cuttings, though it does not typically branch much if at all unless the growth point is damaged. Provide strong light for greatest long-term stability.

[ Echeveria 'Dark Vader' | Posted on September 20, 2020 ]

Ornamental Echeveria hybrid with an unusual form and color. Leaves are folded (monstrose) like "Topsy Turvy" but dark like "Black Prince", with a powdery covering on top. "Dark Vader" is a Volarth Chi hybrid of E. runyonii "Topsy Turvy" and E. "Black Prince". Also known as "Darkness Power" in Asia and "Dark Hawk" or "Black Hawk" in Australia.

[ Cathedral Window Haworthia (Haworthia cymbiformis) | Posted on September 17, 2020 ]

Windowed rosette succulent, usually prolifically clumping, from the Eastern Cape in South Africa. This plant is similar to H. cooperi, another Haworthia with windowed leaves, and occupies much of the same territory in habitat. The leaves are pale green but they may turn dramatic orange or yellow colors when stressed. Its habitat may be a summer rainfall zone, but this plant does well in our winter rainfall climate. The roots are quite shallow, so avoid deep pots. Provide strong light for the best, most compact form and strongest color.

The former H. planifolia is now considered to be a form of cymbiformis. Natural hybrids are know to exist with H. angustifolia and H. cummingii. The former H. cuspidata is related to cymbiformis, and is treated by the CoL as a synonym of Star Window Plant (Haworthia cymbiformis var. cymbiformis), but it may in fact be a hybrid between cymbiformis and retusa. Some of the images on this page (and the page for var. cymbiformis) may be cuspidata. A number of other varieties have been described.

[ Gasteria 'Big Brother' | Posted on September 12, 2020 ]

Warty distichous Gasteria, sibling to Gasteria 'Little Warty', with large raised areas of pale green and smaller areas of dark green forming rough stripes along the leaves. These color patterns, as well as the surface texture that accompanies them, are variable from one leaf to the next. Leaf tips are truncate (flat). The rosette may grow to about 8 inches wide. This plant supposedly does not offset, but it can be forced to branch by coring and may also be propagated from leaves. Parentage: Gasteria batesiana x 'Old Man Silver'. A Cumming hybrid.

[ Silver Jade (Crassula arborescens) | Posted on September 8, 2020 ]

Large leafy shrub or small tree from South Africa with round, fleshy, usually red-edged leaves and white or pinkish flowers. Easy to propagate from leaves or cuttings. The succulent leaves are pocked with epidermal hydathodes almost exclusively on the upper surface and may be varying degrees of glaucous depending on the light. Leaves may persist for a long time on old plants but leaf loss in times of drought can lead to exposed stems. In cultivation this plant is susceptible to scale, which may be well camouflaged by the powder on the leaves.

[ Saw-Leaf Agave (Agave xylonacantha) | Posted on September 2, 2020 ]

Small greenish agave with narrow leaves and extreme teeth from east-central Mexico. Ornamental, savage. Solitary or offsetting. Open rosettes may reach up to 3-4 feet, with relatively few leaves. The species name means "wooden spine" and refers to the gnarly, irregular, flattened teeth on leaf margins. The leaves may or may not be glaucous, and they may or may not have a pale center stripe. Yellow is a stress color. Margins are corneous, with prominent teats, and teeth may be multicuspid. Found at higher altitudes in Nuevo León, Tamaulipas, San Luís Potosí, Hidalgo, often growing on limestone. Some plants may be difficult to distinguish from A. univittata.

[ Bromeliad (Dyckia) | Posted on August 31, 2020 ]

This genus of about 120 species of terrestrial bromeliads is native to arid, rocky, often higher altitude areas of central South America, especially Brazil. These spiny plants are dry growing and typically enjoy the same conditions that succulents prefer: strong light, fast draining soil, water when the soil has gone dry. Do not treat them like epiphytic bromeliads. They tolerate some drought but prefer regular water in moderation during the warmer months.

The flowers are typically tubular, colorful hummingbird magnets. The fruit is dry and dehiscent. Seeds are flat and unwinged. Some or many plants in cultivation may be self fertile, and seedling growth is slow for the first couple of years. The Dyckias that offset can be easily propagated from rooted cuttings, but this process may take a while. Baby Dyckias (just-rooted offsets) may look quite different from their mature counterparts.

There are lots of Dyckia cultivars and hybrids in cultivation. Do not assume any random, unlabeled Dyckia you bump into is a species. Some of the more desirable cultivars have red/purple, glossy leaves or silvery leaves coated with trichomes. The very desirable cultivar Dyckia 'Brittle Star' has narrow purple leaves with lots of trichomes. Dyckia cultivars are frequently mislabeled and misidentified.

Dyckias may be easily confused with Hechtias (a mostly North/Central American genus), but upon flowering the difference is clear because Hechtias are typically dioecious (plants are 2 different sexes) whereas Dyckias are not. Other differences in the flowers (especially color) may be evident from a distance. While Dyckias flower laterally, Hechtias may flower terminally (resulting in the death of the flowering rosette), laterally (the flowering rosette lives on indefinitely), or both, depending on the species.

[ Aeonium 'Mardi Gras' | Posted on August 25, 2020 ]

Small, branching variegated Aeonium with tricolor leaves (red, white, green). Unlike other older, more common variegated Aeoniums, this plant seems to be relatively weak and vulnerable to too much sun. Dramatic seasonal variation occurs: winter leaves are greener, more numerous, longer, and with a rounded tip; summer leaves are redder, darker, fewer, shorter, and nearly truncate (flattish) at the tip. Reversions (loss of the white stripes) sporadically pop up and these rosettes seem to be stronger, so remove these branches to favor the variegated ones. Overpot slightly to encourage branching.

[ Calibanus (Beaucarnea glassiana) | Posted on August 8, 2020 ]

This second species of Calibanus (now under Beaucarnea) was described in 2003. It has the same growth habit as B. hookeri: a wide, low caudex which does not rise much above the ground, topped by tufts of leaves in rosettes. It has fewer branches, much longer leaves, longer and more branched inflorescences, and smaller fruits than B. hookeri.

[ Ponytail Palm (Beaucarnea recurvata) | Posted on August 8, 2020 ]

This succulent tree from the tropical deciduous forests of eastern Mexico has a wide, enlarged base, recurved and reflexed leaves, and tiny unisexual flowers. It may reach up to 15-50 feet tall; the base may be 6 feet or more wide in old age. It is not any kind of palm, despite the English common name, being more closely related to yuccas and agaves. It is called "pata de elefante" (among other names) in Mexico.

It is propagated from seed (which requires separate male and female individuals in flower to produce) or rooted cuttings. Plants started from cuttings will not tend to develop the same extra-wide, bottom-heavy proportions, and are generally less desirable. They are often beheaded at a relatively young age to take another cutting and start a new plant, thereby forcing branching near the base. Here's an example of the way the plant responds to the loss of its growth point. Otherwise branching is typically associated with flowering, which occurs relatively late in life. Since flowers are terminal (the growth center turns into an inflorescence) the only way a stem can continue growing after flowering is to branch at the base of the inflorescence, though perhaps not more than once.

B. recurvata is usually a container plant in cultivation. It is very well behaved (though somewhat limited) in containers, and may flower in them. Provide excellent drainage, strong light, and regular water when the soil is dry at depth. Barring desert heat, it's impossible to provide too much sun.

This is by far the most common Beaucarnea in cultivation (at least 10 times more common than the runner up). A couple of other species in the genus (B. guatemalensis, B. pliabilis) may be confused with it, but can be distinguished based on leaf differences. Another species with a wide, nearly globose base is B. gracilis. Variegated forms of B. recurvata exist, though they are uncommon, and they are typically propagated from rooted cuttings.

B. recurvata is grown in the ground in parts of California and Florida. The Florida plants tend to look dramatically better during the summer because they (unlike the California plants) receive summer water in the form of rain. While this tree tolerates extreme drought, it does a lot better (and looks a lot nicer) when it gets regular water. Likewise, it tolerates extremely confined spaces but will grow considerably faster when allowed some room below ground.

[ Ice Plant (Delosperma echinatum) | Posted on July 30, 2020 ]

Upright to sprawling ice plant with interesting leaves that have lots of spiny-looking (but soft) hairs on them. From a distance the leaf detail is not particularly evident, but it makes a fascinating subject for close up photography, especially when the plant is in flower. Flowers are pale yellow, yellow, or white and just smaller than the leaves. A well behaved plant in cultivation, potentially even invasive in some climates in the ground.

From the Eastern Cape in South Africa. The species name means "spiny" and refers to the leaves. The genus name is neuter because the Greek root sperma is neuter.

[ Haworthia (Haworthia magnifica) | Posted on July 18, 2020 ]

Attractive small Haworthia with windowed, veined leaves that are flattened in a triangular area near the end. From the Western Cape Province of South Africa, often found partly buried in habitat, with just the upper surfaces of the leaves above ground level. A number of named varieties exist. Brown or purplish with sun/drought stress. Variable (thus highly collectable) and often slow to offset. Identifiable based on its short, green-lined flowers and curved buds. Flowers in early fall. This species has been used in hybridization.

The former H. magnifica var. acuminata has apparently become H. pygmaea var. acuminata, according to the CoL.

[ Euphorbia (Euphorbia delphinensis) | Posted on July 17, 2020 ]

Yellow or pinkish flowering crown of thorns relative from Madagascar. Described in 1955. The leaves are dark green and glossy, topping spiny succulent stems.

[ Jewel Leaf Plant (Graptopetalum amethystinum) | Posted on July 17, 2020 ]

Rose or pink rosette succulent with extra chunky, glaucous leaves. Rosettes reach about 4-6 inches wide and stems may grow to a foot or more in advanced age. Flowers are whitish yellow with red highlights. This plant is propagated from leaves.

From Durango, Jalisco and Sinaloa, Mexico. This species is a parent of the popular xGraptoveria "Opalina" and "Debbi" (as well as several other attractive hybrids).

[ Graptopetalum (Graptopetalum superbum) | Posted on July 16, 2020 ]

Lilac or pink rosette succulent with flat, spreading, glaucous leaves. Rosettes reach 4-5 inches wide. Stems are upright, then sprawling, branching mostly from the base. The inflorescence is a laxly flowered thyrse, and the spreading petals have red speckles and red tips.

This species and G. pentandrum (of which it was formerly considered a subspecies) are two of three in the genus whose flowers have 5 stamens (not 10). They were both described first from cultivated material and then later found in nature. They are presumably related to a third, clumping species with 5 stamens, the recently described C. glassii (from a small area in Colima).

This species was described as a subspecies of pentandrum in 1987 and is found in Jalisco, Mexico. It is not uncommon in cultivation, and easily propagated from leaves, like other plants in the genus. It can also be propagated from cuttings. The inflorescence is outsized compared to the plant and the flowers are quite pretty. This species can be distinguished from pentandrum based on the number of branches in the inflorescence (a dozen or more, compared to 3 or 4), among other features (it is also tetraploid, not diploid). It was distributed by the ISI in 1986 as ISI 1661.

[ Euphorbia 'Cocklebur' | Posted on July 12, 2020 ]

Attractive hybrid succulent Euphorbia with many small heads, each bearing tubercles and small green leaves. Rather than growing a main stem with orderly branches from there, this plant tends to branch profusely in every direction, yielding heads stacked on top of heads.

This hybrid (said to be E. bupleurifolia x susannae, and intermediate between those species) is most commonly known as E. x japonica, and is reasonably common in the trade because it is very easy to start from cuttings. In my hands it does not flower. The root system is insubstantial and deep pots should be avoided. Growth occurs year round under permissive conditions. Provide excellent drainage and strong light, and avoid overwatering. Old plants may reach about 8-10 inches wide.

There are similar-looking multiheaded plants in cultivation with greener stems that may also be hybrids of bupleurifolia and/or susannae.

[ Haworthia (Haworthiopsis reinwardtii) | Posted on July 8, 2020 ]

Small Haworthia with stacked leaves that form narrow, tall rosettes. Leaves are marked with many raised white tubercles. Stems branch at the base (or higher up, if there is injury to the growth point) and form sprawling clumps in old age. This plant is very well behaved in small(ish) containers, given good drainage and strong light, but not necessarily a lot of direct sun. Ridiculously easy to start from cuttings. A single plant in an 8 inch pot can provide dozens of cuttings to start new plants over the course of several years without needing more space or any kind of soil replacement. My plants do not flower, unlike the other Haworthias here.

This species occurs in the Eastern Cape province of South Africa near Grahamstown. It is very similar to H. coarctata and occurs mostly to its east. The two species may be difficult to tell apart but reinwartdtii tends to have larger, whiter, flatter tubercles.
