This American classic looks great in the left-most photo above, grown with grasses and the seedheads of Monarda, or in this closer shot. Shown is the popular variety ‘Goldstrum,’ voted Perennial of the year in 1999.
The species is native to the Southern and Eastern U.S.
Details
- Long bloom time, from July into September.
- Requires full sun or light shade.
- Spreads freely by seedling.
- Hardy down to Zone 3.
Care
- Fairly drought-tolerant once established. (Newly planted, they need to be watched and watered regularly their first season.)
- No need to divide.
- Most gardeners leave the attractive seedheads standing all winter for the birds. Others remove the dead flowers to prevent spreading.
- Pinching in May can produce bushier, shorter plants, but I’ve never done it myself. The variety ‘Goldstrum’ is short enough to not need pinching.
