Morphology
About
Begonia dregei is a fascinating caudiciform species, endemic to the rocky slopes and forest margins of eastern South Africa. It thrives in seasonally moist habitats, preferring bright, filtered light and well-drained, humus-rich substrates. This begonia develops a distinctive swollen, tuberous base and a multi-branched, shrubby habit. Its small, asymmetrical leaves, rounded to ovate with shallow lobing, are borne on slender, reddish petioles, contributing to its attractive bonsai-like appearance over time.

South Africa's Drought-Tolerant Contribution
Begonia dregei from South Africa's rocky slopes — the drought-tolerant anomaly in a genus of humidity-lovers. Catalogued here as a broader genus entry. At accessible price tier. Worth noting that dregei is one of those plants that punishes being treated like a Bornean forest floor species — it wants the periodic dry-out that its rocky South African habitat provides. A useful reminder that the genus Begonia spans a remarkable ecological range: from permanently humid limestone cliffs to seasonally arid rocky outcrops, with the horticultural requirements diverging accordingly.
