Care Guide

Do

Provide full sun for the best foliage color and most abundant flowers.
Prune annually in late winter to maintain a compact shape and promote blooms.
Deadhead spent flowers to encourage reblooming.
Water regularly during the first growing season to establish roots.

Don't

Do not plant in deep shade, as foliage will be green and flowering will be poor.
Avoid letting the soil become waterlogged.
Don't be afraid to prune it hard; it blooms on new wood.
Avoid high-nitrogen fertilizers which can promote leaves over flowers.
