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

HYPERICUM

All bear single flowers with prominent sunburst of stamens in 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 used for mass plantings, ground covers, informal hedges, 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.

Clusters of 3/4-in., golden yellow flowers in summer.

'Glacier'

Most gardeners grow this 3- to 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.
