Miracle Primo St. John's Wort
Miracle Primo St. John's Wort (Hypericum x inodorum 'Allprimo')
Miracle Primo St. John's Wort is a compact shrub that keeps the garden looking colorful for months by shifting from summer flowers to a distinctive berry finish. Bright yellow blooms bring a clean mid-season lift, then pale berries extend interest into late summer and fall when many borders start to lose momentum. The dense, mounded habit fits easily into foundations and mixed beds without taking over the space. If you want long-season impact in a manageable size, this plant delivers reliable results with straightforward care.
Distinctive Features
This selection forms an upright, bushy mound with deep green foliage that stays tidy through the growing season and can develop subtle red tones in cooler fall weather. Summer brings a steady display of golden yellow flowers, followed by rounded berries that are typically described as white to pale cream as they mature. The berries add a second season of interest and can be used for cut stems in late summer and fall. Mature size is commonly about 28 to 32 inches tall and 24 to 30 inches wide.
Growing Conditions
- Sun: Full sun to part shade, with best flowering and berry set in full sun.
- Soil: Average, well-drained soil is ideal, and avoid sites where water sits around the roots.
- Water: Keep evenly moist during establishment, then water during extended dry periods.
- USDA Zones: Zones 6 to 9.
- Mature Size: About 28 to 32 inches tall and 24 to 30 inches wide.
- Habit: Upright, bushy, mounding shrub with dense branching.
Ideal Uses
- Focal Point: Use the flower to berry transition as a focal point near a walkway or patio where late-season fruit color can be enjoyed up close.
- Foundation Planting: Place in front of taller shrubs for a tidy mid-layer that stays full and presentable.
- Border Planting: Repeat in sunny borders to create consistent mounded structure with long seasonal interest.
- Container Feature: Grow in a large container for a compact shrub that looks good from bloom through berries.
- Cut Stem Garden: Plant where fruiting stems can be harvested for arrangements and seasonal decorating.
Low Maintenance Care
- Watering: Water regularly the first season to establish roots, then reduce frequency as the plant settles in.
- Mulching: Mulch to conserve moisture and reduce weeds, keeping mulch a few inches away from the stems.
- Pruning: Prune in late winter to early spring to refresh shape and encourage vigorous new growth and flowering.
- Fertilizing: Feed lightly in spring if needed, and avoid heavy fertilizing that can reduce flowering and berry set.
- Cleanup: Remove winter-damaged stems in spring and thin lightly if the center becomes crowded.
- Drainage: Maintain reliable drainage to support healthier foliage and stronger bloom performance.
