Hypericum ‘Hidcote’

St. Johnswort
Hypericaceae
Evergreen, Perennials, Shrubs, Semi-evergreen

HYPERICUM

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 ‘Hidcote’

Grows to 4 ft. tall and 5 ft. wide in mildest climates; in cold areas, it acts more like a root-hardy perennial, freezing to the ground and only growing back to about half its potential size. Dark green, 2–3-in. leave give rise to yellow, 3-in. flowers all summer long.
