Establishment
First growing season (3-4 months)Young plant developing root system and initial branching structure
Water regularly to establish roots. Apply 2-3 inches of mulch around base, keeping clear of stem. Prune lightly to encourage branching.
Vegetative Growth
Spring through early summer (3-4 months)Plant puts on leafy growth, developing a compact mounding form with glossy green foliage
Fertilize monthly with balanced fertilizer (10-10-10) during spring and summer. Maintain consistent moisture. Prune in early spring to shape and maintain size.
Flowering
June through October (5-6 months)Abundant golden-yellow flowers with prominent red stamens appear abundantly across the plant
Continue regular watering and monthly feeding. Deadhead spent flowers to encourage continuous blooming. Ensure adequate sunlight for maximum flower production.
Fruiting
August through December (5-6 months; overlaps with flowering)Yellow-green berries form at flower sites, gradually maturing through red to deep purple-black
Reduce deadheading to allow berry formation. Minimize pruning during this period. Ornamental berries attract birds.
Dormancy/Semi-dormancy
December through February (2-3 months)Plant slows growth; retains some foliage (semi-evergreen); purple-black berries persist on branches
Reduce watering significantly but don't allow soil to completely dry out. Minimal fertilizing needed. Prune out any winter damage in early spring.

Harvest Tips
Hypericum 'Fiesta' is grown for ornamental flowers and berries rather than harvest. Cut stems with flowers for fresh arrangements from June onward. Allow berries to remain on plant for fall and winter interest, or cut branches with mature berries for dried arrangements. Cut dried berry stems after they turn deep purple-black, typically in fall.
