Once planted, leave undisturbed. May not bloom for several years after planting. Staking plants before they bloom is a good idea because flower heads are heavy. Plants bloom in late spring. Use balanced fertilizer after bloom.
Foliage is very attractive and resembles a shrub from spring until late fall.
Clumps get bigger each year. No particular growing problems. Thank you for your attention. Ferry-Morse Seed Company. All Rights Reserved.
