(aka: C. 'Multiflora) This Agri-Starts introduction is a sport of the old favorite C. esculenta 'Burgundy Stem'. Each dark grey-green leaf is highlighted by random purple-black sectors and flecks. Despite the instability of the pattern, the patterning does persist throughout the entire plant. Due to this instability, C. 'Black Marble' has a high cull rate in production and will never be produced commercially in huge numbers. Enjoy them while they last.
