Hypericum (St. John’s Wort)

(D = deciduous leaf losing and E = evergreen)

The shrubby St. John’s worts are attractive plants, usually with large, golden-yellow flowers with a central brush of stamens in late summer. Plant from October to November or from February to March in a well-drained soil.

Hypericum calycinum (rose of Sharon) (E), 1-½ ft., flowers all the summer, and grows well in shade and on dry, chalky soils, but must be planted carefully as it is inclined to spread unduly. Clip drastically each spring once established.

H. moserianum (E), 1-½ ft., with 3-in. wide flowers from July to October, suitable for ground cover when planted closely.

H. patulum Hidcote (E), 5 to 6 ft., an elegant hybrid, with large, saucer-shaped flowers. Needs a little shelter in exposed gardens.

H. Rowallane Hybrid (E), 7 to 8 ft. in mild districts, probably the best hypericum produced so far. Its 1-½ – to 3-in. wide flowers are borne profusely. Needs a little shelter in exposed gardens.
