Suggestions
Growing Suggestions:
- Can be used as a filler in hangings baskets, containers or window boxes to trail over the edges.
- Well-draining soil is necessary as the plant does poorly in soggy soil which will cause stress to the plant and may lead to root rot. Water only when the soil is dry.
- Deadheading is not required and they drop spent flowers on their own.
