Description

Cobalt-n-Gold™ Hypericum (Hypericum kalmianum ‘PIIHYP-I’) is a compact, mounded selection of Kalm St. John’s wort chosen for its fine silver- to blue-green foliage and blankets of bright golden yellow blooms in late spring and early summer. The cup-shaped flowers, packed with showy stamens, completely cover the shrub, then give way to warm yellow, orange, and red fall color that reveals cinnamon-brown exfoliating bark for four-season interest. Bred in 2008 in Watkinsville, Georgia, as part of a Plant Introductions, Inc. program and selected for stronger stems and tighter habit than its parent, it’s marketed in the First Editions® line as a tough, low-maintenance native shrub that thrives from the Upper Midwest to the Southeast, tolerating drought, salt, a range of soils, and browsing deer while providing excellent color and pollinator value in modern landscapes.

Compact, mounded shrub with fine silver-green to blue-green foliage and strong, non-splaying stems.
Smothered in ¾" golden yellow flowers from late spring into summer, then develops vivid yellow-orange-red fall color and showy exfoliating bark for multi-season interest.
Adaptable, low-maintenance native selection: hardy in cold climates, tolerant of drought, dry and rocky soils, and salt, and notably deer resistant.
