| Maintenance | Fall cleanup will require good lopping shears to cut the thick stalks. It seems that the plant loses some vigor as the clumps get older. I divide them every 3 years or so to rejuvenate the growth. Depending on the growing conditions, it may need to be staked. |

| Author's Notes | I try to use this plant when ever possible. It is a true landscape perennial producing a cloud of white blooms. I have one in a garden and as dusk approaches the plant seems to glow. If you want it as a specimen plant allow 5 feet to spread. |
