Description: This rhizomatous Begonia from the dim understory in the montane forests of Malaysia produce strikingly iridescent leaves under ideal growing conditions. Due to a uniquely ordered arrangement of tower-like thylakoids in the chloroplast, light is slowed down in a quantum physics effect known as "slow light". Combined with an increased uptake of red-green light this increases the efficiency of photosynthesis by up to 10%.
Culture: Prefers cooler temperatures of mid 50's to low 70's. Blue iridescence develops best in deep shade. Prefers slightly alkaline soils, high humidity, and constantly damp roots.
