Hypericum androsaemum ‘Glacier’

St. Johnswort
Evergreen, Ground covers, Shrubs, Decorative fruit or berries


All bear single flowers with a prominent sunburst of stamens in the center. Shal­lowly cup-shaped, five-petaled blooms range in color from creamy yellow to gold; flowers may be solitary or in clusters. Neat, fresh green foliage. Various species are used for mass plantings, groundcovers, informal hedges, or borders. Grow especially well in mild, moist regions.

A difficult-to-control rust is extensively infecting plantings (especially those of the species H. calycinum) in the Pacific North­west. Remove and destroy blighted leaves and any leaf litter; avoid overhead watering of plants in the evening.

Hypericum androsaemum

Shade-tolerant semievergreen native shrub from Europe and western Asia. Grows to 3 ft. tall and wide, with stems arching toward the top. Leaves are medium green above, paler beneath, to 4 in. long and 2 in. wide. Clusters of 3/4-in., golden yellow flowers in summer. Blossoms are followed by inedible berrylike fruits that turn from red to purple to black as they age. Useful as a tall groundcover at the edge of woods, on shaded slopes, or in a wild garden.

Most gardeners grow this 3–4-ft. shrub for its wonderfully variegated leaves. They’re variegated pink when new, then become green heavily splashed with white. Yellow flowers and tiny, apple-like red berries also make it worthwhile.
