Notes: Cobalt-n-Gold Hypericum is a North American native selection shrub with a mounded form and fine blue-silver foliage. In late spring to early summer, it’s blanketed with ¾-inch sunny yellow flowers that attract pollinators. During winter, its exfoliating bark adds striking interest to the landscape. This hardy shrub thrives in full sun and well-drained soil, adapting well to many regions across Zones 4–7. Reaching 2–3 feet tall and 4–5 feet wide, it’s an excellent choice for foundations, borders, or low hedges.
