The Jackman Potentilla is a native Illinois perennial that produces
bright yellow flowers throughout the summer. The potentilla does well in
sunshine and can survive in some shade. They can be used as foundation
plantings, in low hedges and in masses.
When dry weather arrives, be sure and water them. If they dry out, then the
flowers will be affected. Trim in late winter or early spring. Remove dead
branches and you can trim the entire plant by half. Do not trim once spring
growth has started.
Avoid placing your potentillas in soggy soil as the plant will probably die.
The plant forms a small round mound with many small flowers.
