These haworthia magnifica v atrofusca mutant have the largest and clearest epidemal windows I've seen! The contrast of the silvery looking windows with the dark green stripes really makes for a striking specimen.
These do best in bright light but not in direct sun and are cool season growers. Plant in very gritty/well draining soil and water sparingly during hot months when they're dormant.
Approximately 2½ - 3" diameter with sparse/minimal roots
