| Grown for its rose-red colored, double flowers that bloom summer to fall. This popular, long-lived perennial with a woody base reaches up to 36 inches. 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. |
