Rose-Pink is very easy to grow, and will adapt to poor or rich soil alike. It prefers a moist environment in full to part-sun, but will also perform well in poorly drained, or rocky and sandy conditions. It really is hard to go wrong with this species. As a biennial, it completes its life cycle in 2 years, however, its ability to self seed allows it to establish a perennial presence in a flower garden. The plants are shallow-rooted, so they are easy to move around in the garden in fall of their first year, or early spring of their second. A great filler plant. It will also naturalize in a wild garden setting, or in open prairies, meadows, and marshes. The blooming period is long, lasting 2 months or more, and occurring mid-summer through early fall.
