Hypericum frondosum 'Sunburst'

Sunburst St. John's Wort

Hypericum frondosum ‘Sunburst’ is a deciduous shrub valued for its large bright golden-yellow flowers with prominent tufted stamens and distinctive blue-green foliage. Blooming in summer, the flowers are larger than many other Hypericum selections and stand out strongly against the glaucous foliage. The rounded shrub form and vivid flower display make it especially attractive in sunny landscapes.
