When to plant Eastern Bluestar
Eastern bluestar is a native perennial that blooms in April and May; Clemson describes adding it to the garden in spring and notes light afternoon shade is best in hot climates. The page gives no explicit planting date, so a spring band is approximate.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
