The Story
Plant Bio
Orostachys iwarenge is a monocarpic succulent that forms tight rosettes of fleshy, silvery-green leaves. It spreads by runners to form a dense mat.
After a few years, each rosette sends up a conical flower spike covered in small, star-shaped white flowers. After flowering, the parent rosette dies but the surrounding offsets continue to grow.
