Miracle Grandeur St. John's Wort

Miracle Grandeur St. John's Wort (Hypericum x inodorum 'Allgrandeur')

Miracle Grandeur St. John's Wort is a compact shrub that keeps the garden colorful from summer into fall, moving from bright yellow flowers to a strong berry finish. The tidy, mounded habit fits easily into borders and foundations where you want a clean look without constant trimming. Glossy green foliage holds the plant together between bloom flushes, so it still looks intentional when flowers are not at their peak. It is an easy way to add long-season interest in a manageable size.

Distinctive Features

This selection forms a dense, rounded shrub with deep green leaves and a long flowering window of bright yellow, cup-shaped blooms with prominent stamens. After flowering, it sets showy red berries that extend seasonal color into late summer and fall, adding a second wave of interest beyond bloom. The overall habit is upright, rounded, and mounding, staying compact and well-branched rather than loose or sprawling. 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 color in full sun.
• Soil: Average, well-drained soil is ideal, and it adapts well as long as roots do not sit in water.
• 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, rounded, mounding shrub with dense branching.
• Notable Traits: Yellow summer flowers followed by red berries that extend interest into fall.

Ideal Uses

• Focal Point: Use the flower-to-berry transition as a focal point near a walkway or patio where the late-season berry color can be enjoyed up close.
• Foundation Planting: Place in front of taller shrubs to create a tidy mid-layer with long seasonal interest.
• Border Planting: Repeat in sunny borders to create a consistent mounded form with reliable summer color.
• Low Hedge: Plant in a loose line for a compact flowering edge that finishes the season with berries.
• Container Feature: Grow in a large container for a seasonal accent that stays full and presentable from summer into fall.

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 shape the mound 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 any winter-damaged stems in spring and thin lightly if the center becomes crowded.
• Drainage: Avoid persistently wet soils to support cleaner foliage and better long-term performance.
