Polemonium yezoense (Jacob’s Ladder) Bressingham Purple

Where to Buy

US & Canada|UK & Ireland


Beautiful flowers of deep electric lavender-blue appear in late spring/early summer, rising in elegant clusters on graceful, sturdy burgundy stems above the attractive mounds of foliage. Highly decorative fernlike leaves are neat, uniform and symmetrical, like most varieties of Jacob’s Ladder, but with a colorful twist: The foliage takes on a rich, dark purple hue in spring and again in Autumn. In between, the leaves turn somewhat greener or even fully green in summer, depending on light intensity. A Must Have Perennials selection from Adrian Bloom.

Aftercare Instructions

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 and to encourage a possible late summer rebloom.
