The Giant Mosiac Coleus (Solenostemon scutellarioides) is a drama waiting to happen with his colossal leaves. The colors are vibrant enough to add pizazz to any shady garden where a limited plant palette grows. Add him to your hanging baskets and porch containers for seasonal color, then transplant him into the house for a winter show. The leaves can grow 12 inches long, and the whole plant grows to 18"-20" tall and 15"-18" wide. Space him and his siblings 15-24" apart in the garden beds but don't worry, they don't sleep!
