Blackberry Chimera: When Leaves Turn Half White

Finding blackberry leaves that are completely white or half white/half green indicates a chimera—a genetic mutation in a bud causing some cells to lack chlorophyll. This is how many variegated plants originate.

Variegated plants like 'Burgundy Glow' ajuga or variegated hosta started as chimeras. While some are attractive and propagated commercially, others lack enough chlorophyll to thrive. The variegated blackberry could potentially be propagated from stem cuttings (root sprouts won't carry the trait).
