Polemonium 'Bressingham Purple'

Grow in average, medium moisture, well-drained soils in part shade to full shade. Best leaf color may occur in part shade. Prefers rich, humusy, consistently moist soils. Soils must not be allowed to dry out. Best performance occurs in cool summer climates. Plants are intolerant of the high heat and humidity of summers in the deep South. Plants may be cut back to basal foliage after bloom or if foliage declines to tidy the planting and to encourage a possible late summer rebloom.
