Growing & Maintenance Tips
Grow in an average, medium, well-drained soil, in full sun or partial shade. Heavy soils and winter wet can result in increased winter survival problems. Will freely self-seed in optimum growing conditions. It is tolerant of heat, humidity and drought and cutting some of the stems in half partway through the blooming period will extend the flowering period.
