Appearance and bloom

Himalayan spiraea is much-branched, deciduous shrub with narrow, lance-shaped leaves providing fine structure. Plant reaches height of one point five to two point five metres and forms dense, elegantly rounded crown. White flowers appear in spring from May to June in dense, festive clusters covering entire shrub. This flower form gives plant very ornamental appearance, especially when entire shrub is in bloom. Flowers attract butterflies and bees and give garden natural vitality. After flowering, blooms disappear and plant foliates completely for green summer appearance.

Ideal location

Himalayan spiraea thrives best in sunny to semi-shaded location. Ensure at least four to six hours of direct sunlight per day for optimal flowering. Plant is very wind-resistant thanks to compact, strong growth habit. So do not plant this shrub behind windbreaks, but make it structural element in your garden. Plant tolerates wind gusts well, making it ideal for exposed locations throughout the year.

Soil

Well-draining soil is essential to prevent waterlogging and root rot. Add compost when planting to improve soil quality and create better growing conditions for long term success.

Watering

Once established, Himalayan spiraea establishes itself well with minimal watering. During dry periods in growing season from May to August, extra water may be beneficial. Young plants under two years old deserve more attention with watering. Adult plants are fairly drought-tolerant and can grow without supplemental water in normal years with adequate natural rainfall.

Pruning
