Hypericum Sunny Boulevard
St John’s Wort is a familiar sight in many cottage gardens, but Hypericum kalmianum Sunny Boulevard is particularly prized because it is a compact and nicely rounded shrub that can be planted in the centre of a border without fear of domination. The wonderfully warm yellow of the five petalled flowers are made more beautiful by deep fringes of stamens around the flower’s eye.
- Pot size: 3L
- Height and Spread: 60 -90cm (2-3ft) x 60 -90cm (2-3ft)) after 2-5 years

Hypericum is indigenous in Europe and S W Asia and was taken by settlers to North America for its medicinal properties. It is used to treat skin irritations and depression, but its chemical makeup can interfere with other drugs. Called St John’s Wort, Hypericum is almost invariably in flower on the 24th June, John the Baptist’s birthday; its other name is Rose of Sharon.
