Year-round

Fall
Fall is bloom season, with white flowers from August into October.
- Flowers open in late summer and carry through fall.
- Soil can be moist to occasionally dry.

- Seed heads stay on the plant from fall into winter.
- Leave dormant plants alone and cut back when new growth starts.
Spring
Spring is a good time to plant or divide, and growth picks up.
- Plant or divide clumps from seed or division.
- Choose sun to part shade with well-drained soil.
- Space plants so air can move through, since mildew and leaf spot can show up.
Summer
Summer is growing time, and plants handle dry stretches fairly well.
- It tolerates dry soil, so water only in long dry spells.
