We’ve had ‘Black Coffee’ for almost a decade, and it has been a tried and true rhizomatous begonia for us, with matte almost black star shaped leaves and short stems bearing pale pink flowers. in winter and spring. Plants are slow growing, preferring well drained soil and a fair amount of humidity. Our plants seem to have less ruffled leaves than when we first acquired them. Makes a great container plant indoors or for shady summer containers.
Hardiness zone: 10-11
