Description
This introduction has become one of the most popular perennials in recent years. Full, well branched plants grow 2 1/2-3 tall when situated in full sun. Flower spikes are covered with beautiful florets in shades of buff, lavender and soft rose. Primary bloom begins in June and is followed by a lighter bloom period that continues into September. Wonderful in fresh arrangements. Remove spent flower spikes to encourage more bloom.
How to Grow
Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.
Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry.
Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Garden-tone, as higher rates may encourage root rots.
Plants may need staking.
Remove spent flower stalks to the basal growth to encourage fresh basal growth.
Remove and discard foliage after a hard frost in fall.
In colder regions, apply another layer of mulch (1-2 inches) after the ground freezes in fall. Evergreen boughs (from Christmas trees) provide additional protection. Remove this mulch in the spring.
