Water consistently, especially during dry periods, but avoid waterlogged conditions. Allow the top inch of soil to dry out between waterings to prevent root rot.
Deadhead spent flowers to encourage more blooms and prevent self-seeding. Trim back leggy growth in late summer to maintain a tidy appearance and promote bushiness.
Easily grown from seed sown directly outdoors in early spring or fall. Can also be propagated by division of clumps in early spring.
Not typically grown in pots. If container-grown, repot in spring when roots fill the pot, using a well-draining potting mix.
