| Info | Blue green with an irregular yellow margin. Rugose and puckered. White flowers. Fertile. Medium sized leaves thast are dark blue-green with a wide yellow margin. Glaucous blue-gray, nicely textured leaves with a wide yellow margin. A sieboldiana hybrid, but considerably smaller than 'Elegans', 'Francis Williams', etc. In fact, I assumed this was a Tokudama when I first saw it, since it looks like a reversed 'Bright Lights'. White flowers. Impressive, non-burning, strong gold margin. Leaves have heavy substance, are leathery and slug resistant. Blue-green with yellow margin, rugose. White flowers. |
