How to Grow
This resilient Hypericum thrives when planted in areas receiving full sun to partial shade, though it can tolerate deeper shade if necessary. The most crucial aspect of its culture involves soil preparation: plant in moist but well-drained soils.

Pruning is seldom required to maintain shape, given its naturally well-branched, upright habit. Minimal shaping can be done immediately after flowering if heavy rejuvenation is desired. While this hybrid may self-seed occasionally, it is not considered invasive. The Hypericum × inodorum ‘Kolsan’ FLORALBERRY SANGRIA is generally robust, though occasional monitoring for mild powdery mildew is advised.

Companion Planting
When siting Hypericum × inodorum ‘Kolsan’ FLORALBERRY SANGRIA, consider companions that appreciate similar moisture levels but offer contrasting leaf texture or late-season interest. Plants like hostas or ferns thrive in the partial shade this shrub tolerates, providing deep green, broad leaves that contrast nicely with the shrub’s finer texture. For sunny conditions, pairing it with late-blooming Japanese Anemones or ornamental grasses will complement the yellow flowers and red berries without competing aggressively for moisture.
Seasonal Care Calendar
Spring is the ideal time for preparation; applying a thick root mulch will help moderate soil temperatures and retain moisture throughout the growing season, especially important for young plants. As summer arrives, focus on consistent watering to maintain medium moisture levels, particularly when establishing the plant or during dry spells. Deadheading the spent yellow flowers is generally unnecessary for Hypericum × inodorum ‘Kolsan’ FLORALBERRY SANGRIA since the fruit is the main ornamental feature, though light shearing post-bloom can encourage denser fall foliage color. Minimal care is required in the fall other than ensuring mulch is adequate before the first hard freeze hits Zone 5 gardens.
