Heartseed is a host plant for several butterflies. Other than the Silver-banded Hairstreak, these butterflies are not found in many states and then, only in specific portions of the states.
Amethyst Hairstreak, Miami Blue, and Silver-banded Hairstreak caterpillars eat this plant in Florida. In Texas, the Common Banner and Silver-banded Hairstreak use it as a host plant. These species are found in only the southern tip of the two states, other than the Silver-banded Hairstreak (see map image).
The very reason for the names of this plant is evident in these photos. The black seed has a white heart on it. The seed pods are a round empty, other than a few seed, seed pod/puff/balloon.
The plant is grown in gardens for its foliage rather than the tiny white flowers.
