I first found a Viola “Heartthrob” for sale at a local nursery and it had rather large leaves for a viola. No flowers at the time but these have really neat heart shaped leaves. Heartthrob Violas do bloom with a small violet flower on them in the spring. They form a very tall for a viola clump and do not seem to spread at least in a pot they do not. I have made a new page for them here: Viola “Heartthrob” Accent Plant under Accent Plants/Kokedama and Bonsai Basics pages.
