Solenostemon scutellaroides 'Wizard Mix': sprouts

Solenostemon scutellaroides, known in English as "coleus" and in French as coléus or coliole, is a tender perennial native to southeast Asia widely grown for its colourful foliage. Cultivars are available with various patterns of white, pink, red, yellow, brown, black, and green leaves.
