Gardeners' Notes:

I planted some from seed 3 years ago, germination was extremely poor and the intial seedlings were very tiny and slow-growing. However the few plants I did transfer to my garden took hold and have eventually spread to a nice patch of ground cover.

Hypericum - St John's Wort
This is a large and varied genus of 400 species of annuals, perennials, shrubs and a few small trees, some evergreen but mostly deciduous, grown for their showy flowers in shades of yellow with a central mass of prominent golden stamens. They are found throughout the world in a broad range of habitats. Species range in size from diminutive perennials for the rockery to over 10' tall.
Cultivation: Mostly cool-climate plants, they prefer full sun but will tolerate some shade. Thy do best in fertile, well-drained soil, with plentiful water in late spring and summer. Remove seed capsules after flowering and prune in winter to maintain a rounded shape. Cultivars are propagated from cuttings in summer, and species from seed in fall or from cuttings in summer. Some species are susceptible to rust.
