Begonia prismatocarpa doesn't do windowsills — it does terrariums, vivariums, and closed cases where the air stays soft and the light stays low. Good things, it turns out, come in small (and slightly obsessive) packages. This is the smallest species in the entire Begonia genus, native to the humid rainforest understory of West Africa — Cameroon, the Ivory Coast, and the island of Bioko — where it grows almost epiphytically, tucked onto rocks and fallen logs. In cultivation it keeps that same low, mounding habit: tiny jagged leaves rarely reaching an inch, topping out around 6 inches tall. What it lacks in size, it makes up for in flowers — this is a genuinely free-flowering begonia, producing cheerful yellow blooms brushed with orange-red stripes on a near-constant cycle, not just a seasonal show. Care snapshot Light: Low to medium, indirect light — partial to full shade. Bright light washes out the leaf colour. Water: Keep the soil consistently moist and never let it fully dry out. High humidity is non-negotiable for this one. Difficulty: Intermediate — easy inside an enclosed terrarium or vivarium where humidity stays high; more demanding as an open-air houseplant. Pet-safety: Like most begonias, mildly toxic if eaten — can cause drooling and stomach upset in cats and dogs. What you'll receive Every Begonia prismatocarpa we ship is an actively growing specimen selected for its blooms — a living thing, so yours will have its own personality and may look slightly different from the photo. That's part of collecting a species like this one. This isn't a plant you'll spot at every nursery — Begonia prismatocarpa stays mostly in terrarium and vivarium circles, which is exactly why collectors seek it out. Give it a humid home and it rewards you with near-constant blooms and a growth habit that's genuinely its own. Ready to add one to your collection?
