When to plant Princess Flower
Set princess flower out after the last spring frost in moist, acidic soil, with some protection from hot afternoon sun. It is best grown as an annual or container plant below zone 9 and overwintered indoors or in a greenhouse; in zone 8 it dies to the ground and may return in spring.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
