Growth Stages

Establishment

3-6 months

Young transplant with variegated foliage beginning to develop; limited branching

Water regularly to establish deep root system; apply 2-3 inches of mulch; prune out any dead stems; protect from harsh winter winds in first year

Vegetative Growth

Spring through early summer (3-4 months)

Plant develops dense, bushy form with increasingly variegated yellow and green heart-shaped leaves; multiple shoots emerge

Pinch back growing tips to encourage bushiness; continue moderate watering; feed with balanced fertilizer in spring; mulch to conserve moisture

Flowering

Mid-June through July (4-6 weeks)

Small, delicate bright yellow flowers appear at branch tips; flowers are 0.5 inches wide, borne in terminal clusters

Maintain consistent moisture; do not over-fertilize with nitrogen as it reduces flowering; monitor for spider mites in dry conditions

Berry Development

August through October (10-12 weeks)

Flowers fade and berry development begins; immature berries are green, then transition to bright red, becoming darker red by fall

Maintain moderate watering; berries persist on plant; light pruning to shape plant; no deadheading necessary to encourage berry display

Winter Dormancy

November through February (4 months)

Foliage may partially drop in cold areas; red berries persist and provide winter color; plant enters semi-dormant or dormant state

Reduce watering significantly; do not fertilize; remove any winter-damaged branches in early spring; provide shelter from harsh winds in zone 5

Harvest Tips

Hypericum Sunny Heartbeat is grown for ornamental foliage and berries rather than harvest in the traditional sense. Cut branches with berries for fresh or dried floral arrangements in fall and winter. Berries are toxic to humans and most animals but are eaten by birds. Deadheading is not recommended as berry display is the main ornamental feature.
