Featherplume (Formosa)

The Featherplume (Formosa) is generally described as a perennial subshrub or shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer and fall . The Featherplume (Formosa) has gray-green foliage and inconspicuous purple flowers, with a moderate amount of conspicuous brown fruits or seeds. The greatest bloom is usually observed in the indeterminate, with fruit and seed production starting in the spring and continuing until fall. Leaves are not retained year to year. The Featherplume (Formosa) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Featherplume (Formosa) will reach up to 3 feet high, with a maximum height at 20 years of 3 feet.

The Featherplume (Formosa) is usually not commercially available except under contract. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -13°F. has high tolerance to drought and restricted water conditions.
