Growing & Maintenance Tips
Vigorous and easy to grow perennial. Grows best in a moist, well-drained soil, in full sun or partial shade in hot, summer climates. Needs regular moisture. Remove spent flowers to encourage additional bloom and reduce unwanted spread.  Plants naturalize by rhizomes, and can be invasive, especially in optimum conditions.
