Hypericum Radiance St Johns Wort

Hypericum Radiance is a deciduous dwarf shrub with golden flowers and strikingly colourful foliage. It suits a sunny border.

Hypericum is part of the Hypericaceae family that’s also known as St John’s Wort or Gold Flower. It’s native to Asia but has been grown in the UK from 1887 when it was brought back with the Victorian plant collectors.

St. John’s Wort Radiance is a new variety of hypericum. It retains the cheerful golden summer flowers, which measure 3 cms on this variety, but has young pink shoots and bushy variegated green and white foliage. As the foliage matures it turns a darker shade of green.

In warmer areas of the UK this new variety of hypericum is semi evergreen and will hold onto its bushy foliage during the winter. In other areas the foliage drops to reveal a fine framework of arching stems.
