About this plant
Hypericum × inodorum 'Kolros' is a compact, deciduous shrub that produces abundant, golden-yellow, cup-shaped flowers in late spring to early summer. These blooms are followed by clusters of pink, berry-like fruits from late summer into fall. These berries provide a food source for birds during the colder months when other food is scarce.
The plant's foliage consists of well-branched, dark green leaves with burgundy-red undersides, providing an attractive backdrop to the flowers and fruits. 'Kolros' is valued for its long blooming period and the ornamental appeal of its fruits, which add interest to the garden from late summer through fall. It's well-suited for borders, containers, and as a specimen or low hedge.

Design tip
Use ‘Kolros’ where both its flowers and colorful fruits can be seen throughout the season. Golden-yellow flowers give way to clusters of pink fruits, while dark green foliage with burgundy-red undersides provides a contrasting backdrop and extends the plant’s ornamental appeal into fall.
