Euphorbia tubiglans is endemic to the Eastern Cape Province of South Africa, specifically localized in the arid districts near Steytlerville and Willowmore (Great Karoo). It is a highly specialized species first described by the botanist Marloth in 1910. Due to its limited geographic range and slow growth habit, it is a protected species under CITES Appendix II.
Habitat
In its natural environment, this species is a specialist of the karroid scrublands. it grows on stony, shale-rich flats and gentle slopes where it is often found partially buried in the soil or tucked under the shade of small desert shrubs. The climate is characterized by intense summer heat and very low, erratic rainfall. By growing mostly subterranean (underground), the plant protects its succulent tissue from extreme temperatures and herbivores.
Description
Euphorbia tubiglans is a dwarf, perennial succulent prized for its geometric perfection and unique floral morphology.
Caudex & Stem: It typically features a thick, fleshy, and often turnip-shaped underground caudex. Above the soil, it produces a small cluster of globose to cylindrical stems (usually 2–5 cm in diameter). The epidermis is a dull grayish-green to olive, often developing a purplish or bronzed tint when exposed to strong sunlight.
Ribs & Tubercles: The stems are divided into 5 to 7 (occasionally more) prominent, rounded ribs. These ribs are marked with shallow horizontal grooves, giving the plant a neatly segmented or "stacked" appearance. Unlike many of its relatives, it is entirely spineless, though it retains small, blunt leaf scars.
Flowers (The Defining Feature): Its most remarkable trait—and the source of its name—is the tubular shape of the nectar glands (tubiglans). The cyathia appear at the stem tips on short peduncles; the glands are distinctly elongated into green or yellowish tubes, which is a rare feature in the genus.
Cultivation: This is a "slow and steady" grower. It requires an extremely porous mineral substrate (70-80% grit/pumice) to prevent the subterranean body from rotting. It thrives in bright, indirect light to full sun; high light is necessary to maintain its compact shape and deep coloration. It must be kept almost completely dry during the winter dormancy.
All plants are shipped bare-root, without pots or soil.
To prevent excessive nutrient loss during international shipping, which may make it harder for the plant to recover, we usually trim the leaves before delivery. If you prefer the plant to be shipped without trimming, please contact me in advance.
Planting Instructions
Please collect the plants as soon as possible after arrival to avoid delays.
Open the package immediately upon receipt and replant. Do not place in direct sunlight; keep in a shaded or indirect light location for 2–3 days.
After the adaptation period, start watering and gradually transition the plant to direct sunlight.
Care Guide
Light: Requires plenty of light year-round, but avoid direct sunlight, especially during the hottest part of the day.
Temperature: Native to tropical arid–semi-arid climates; temperatures below 5°C (41°F) can cause frost damage.
Watering: Water moderately when the soil is 70% dry or completely dry. ○In the warm growing season: 1–2 times per week ○In the cooler dormant season: 2–3 times per month Adjust according to soil dryness and plant water uptake.
Soil: Best grown in well-draining soil; not demanding on soil type.
Fertilizing: Rarely needs fertilization; recommend using Osmocote A2 slow-release fertilizer once or twice a year.
Shipping Notice
After receiving your order, we require 3–5 days for leaf trimming, soil removal, and drying to ensure safe long-distance transport.
We ship via air freight; delivery time is usually 8–16 days.
During transit, plants may enter dormancy and appear shriveled, discolored, or reduced in size—this is normal. They will recover after proper care upon arrival.
