| Grown for its light pink, single flowers that become paler with age. The outer tepals are slightly darker pink than the inner ones. This popular, long-lived perennial with a woody base reaches 4 to 5 feet tall. Adds color to partial shade, fall borders. Plants in areas with harsh winters will benefit from a fall mulching. Staking may also be necessary, especially to keep plants upright after a rain. Divide in fall or early spring. Slow to establish, but then spreads rapidly. |
