Establishment
3-6 monthsYoung shrub focuses on root development with gradual leaf emergence; minimal flowering.
Water consistently, protect from extreme heat and wind, stake if needed for support. Apply 2-3 inches of mulch, keeping away from stem.
Vegetative Growth
6-12 monthsShrub develops dense foliage with upright, branching growth habit. Leaves are small, narrow, and bright green.
Prune to shape in early spring, remove any dead or weak wood. Fertilize monthly with balanced fertilizer during growing season.
Flowering
6-8 weeksDelicate white or pale pink flowers appear in clusters at branch tips, typically in mid to late summer.
Do not deadhead flowers; allow them to develop into fruits. Continue regular watering and fertilization.
Fruiting & Color
8-12 weeks or longerFlowers fade and bright red, glossy berries develop and mature, persisting on plant for 8-12 weeks or longer. Berries transition from yellow to orange to deep red.
No intervention needed; berries are self-sustaining. Avoid overhead watering which can cause berry drop. Maintain consistent moisture.
Dormancy
3-4 monthsIn colder zones, plant loses leaves; berries may persist into winter providing structure and wildlife food.
In zones 5-6, provide winter mulch protection and shelter from harsh winds. Prune dead wood in spring. Evergreen in warmer zones.

Harvest Tips
Hypericum 'Strawberry' is not harvested for consumption. For floral arrangements, cut stems with berry clusters in early morning when they are most turgid. Cut just above a leaf node to encourage branching. Berries persist 2-3 weeks in a vase. Harvest for dried arrangements any time during the fruiting period; hang-dry bundles in a warm, dark location.
Fun Facts
- 🌱 The name 'Strawberry' refers to the bright red berries that resemble tiny strawberries and change color over several weeks from yellow to orange to deep red, extending the plant's ornamental appeal.
- 🌱 Hypericum berries are actually false fruits (not true berries); they develop from the ovary and are technically called capsules, yet their appearance and use in floristry have earned them the common name 'berries.'
- 🌱 In Victorian times, hypericum was called 'St. John's Wort' and was believed to have protective properties. The modern ornamental varieties like 'Strawberry' were developed in the Netherlands primarily for the cut flower industry in the 1980s-1990s.
