Hypericum x cyathiflorum Gold Cup

St John's Wort

Easy to grow and produces masses of bright yellow flowers

A graceful small shrub with arching branches growing to 90cm (3ft) or less. The narrow, dark green leaves, which are in opposite rows along the branches are the perfect setting for the large, golden cup-shaped flowers which appear freely through summer and autumn. These are much loved by bees which revel in their golden stamens. A very easy shrub to grow which needs little maintenance.


Grow in full sun or semi-shade in beds and borders. Ideal to add summer colour amongst low evergreens under deciduous trees.


Any well-drained fertile soil. Prune in winter to control size and shape if desired. Cut out whole stems to maintain arching habit.

Ideal to plant with Euonymus fortunei 'Emerald 'n' Gold' for a colourful combination at the front of a slightly shaded border

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
