A small caudex from the rocky slopes and crevices of the arid country stretching from southwestern Namibia's Karas Region (Great Namaqualand) into South Africa's Northern Cape — the Richtersveld and northern Namaqualand. The basionym is Ceradia furcata, described by Lindley in 1845; the current name Othonna furcata (Lindl.) Druce dates to a 1917 transfer. The epithet furcata means "forked", and refers to the way the branches divide as the plant grows. From a subterranean tuber roughly 9 cm across the plant sends up slender pale-grey branches into a miniature tree-like form, eventually reaching 50–80 cm in height. Through autumn and spring it carries small succulent leaves and yellow daisy heads; through summer it drops everything and rests completely. Winter-growing. SANBI lists it as Least Concern, but the species has been designated Sensitive because of poaching pressure for the international ornamental trade.
Native climate
Almost no rain falls all year — a hyper-arid setting. Overall a mild climate.

Care
Light & Placement
In habitat this is a plant of low-rainfall semi-desert, tucked into rock crevices and growing on gravelly slopes. Through the autumn-to-spring growing season, give it as much outdoor sun as you can to firm up leaves and branches — keeping the plant in good light is the simplest way to preserve its naturally compact form. Make the most of the weak winter sun on a south-facing balcony or bright window. The hard problem is summer placement for a winter-growing species: the priority is keeping the pot as cool and well-ventilated as possible. Move the pot to bright shade out of direct sun (north-facing eaves or about 50% shade cloth), raise it on a bench, and run a circulation fan. Bring the plant indoors to a bright window once nighttime lows start dropping below 5°C.
Watering
In autumn (September–October), once nighttime lows drop below ~20°C and leaves begin to move, restart with light watering. Through the active season, water deeply about once every two weeks. Stop when leaves yellow and drop in spring — keep the plant fully dry through summer. Watering in summer because "the soil looks dry" is the single most reliable way to kill this species.
Substrate
Drainage first, inorganic-led. Akadama : Kanuma : pumice = 3:3:4, with pumice tuned higher to dry faster. The plant comes from gravelly ground, so a thin coarse-sand or grit topping helps reduce stagnant moisture around the trunk.
Fertilizer & Supplements
Liquid feed at double dilution once a month through the active season, or a pinch of slow-release at repotting. The species is naturally slow; pushing fertilizer leads to stretched branches and a coarser trunk surface.
Temperature & Overwintering
Optimal 15–25°C; above ~30°C the plant slides into dormancy. Aim for a 5°C minimum — damp soil under cold is fatal. Hot, humid summers are harder to manage than the cold months: from June through September, prioritize shade, ventilation, and dry soil.
Starting from Seed
Where to source seeds
Pre-sowing treatment
Soak seeds for about half a day in a mix of a registered seed-treatment fungicide (Benlate or Daconil) and a plant tonic (Menedael; outside Japan, SUPERthrive or a chelated iron / seaweed extract works similarly), each diluted per label. Anything still floating on the surface is probably past its prime. The seeds are small plumed achenes, and their viability depends on how they have been stored.
Substrate
A separate seedling mix, fine-grained and near-sterile: fine Akadama, fine Kanuma, and vermiculite in 1:1:1, sterilized with boiling water or a microwave pass. A thin topping of fine river sand helps anchor the plumed seed and keeps the surface ventilated.
Sowing method
Sow with no covering, or only the thinnest dusting so the seeds remain partly visible. The cottony pappus catches the wind, so place the seed carefully on a pre-moistened surface.
Light & temperature
Bright shade, 15–22°C. Heating to 25–30°C disrupts germination in this winter-grower. In Japan, the standard window is autumn sowing in September through November. Germination starts in 10–30 days and continues unevenly over the following one or two months. Germination depends on seed freshness, but with fresh seed it is reasonably steady.
Watering
Bottom-water 1–2 cm up the pot. For the first 2–3 weeks, prioritize not letting things dry out; drop the level gradually once seedlings are established.
Fertilizer
None right after germination. Once true leaves emerge, a heavily diluted liquid feed once or twice a month — keep it light.
From Germination to Repotting
Germination through true leaves
Continue bottom watering, in bright shade.
Weaning off bottom watering
Phase out gradually over 1–2 months.
First repotting
In the first or second year, once root-bound, in autumn.
Common Pitfalls
Mold & damping-off
- Cause: excess moisture, contamination, poor airflow
- Prevention: sterilize the substrate, refresh the bottom-water, run a circulation fan
Etiolation
- Cause: insufficient light. The active winter season runs through low-sun months
- Prevention: run an LED close indoors, or move to bright shade outdoors on clear days
Seeds fail to germinate
- Cause: stale seed, temperatures too high
- Prevention: use fresh seed at room temperature (15–22°C) without a heat mat — 25–30°C actively suppresses germination
Summer stall and rot
- Cause: watering during summer dormancy, or sitting in hot, humid, poorly-ventilated spots
- Prevention: cut water once leaves yellow in spring; through summer prioritize shade and ventilation, and consider an air-conditioned room
Notes
Wild-collected plants in trade may have been poached — seed-grown stock is the safer choice.
