'Heart of my Heart' is a heartthrob of a flower - showing a deep, intense red color that is unique in our collection. The flower holds up well, not blackening as quickly as other intense reds in high heat and direct sunlight. The bush is upright, medium-large, and branches well. It produces a very large number of delightful 4-5" mini flowers and is excellent for pot culture as well as garden planting. Released 2004 from HVH.
