In the garden

Spiraea japonica 'Odessa'PBR is a deciduous shrub in the Rosaceae with a multi-stemmed, suckering habit that produces flowers from May to July. It suits gardens that want a seasonal display across early to mid-summer and fits readily into mixed shrub plantings or more informal arrangements. Plant in a position receiving full sun or partial shade; a south-, west- or east-facing site will all do well. It tolerates chalk, clay, loam and sand and accepts acid, neutral or alkaline soils provided they are moist but well drained rather than waterlogged. The cultivar manages both exposed and sheltered locations and is rated H6, which is considered very hardy for UK conditions. Use 'Odessa'PBR in mixed borders, shrub borders, cottage or wildlife gardens, and flower beds where a spreading clump can be allowed to develop. The suckering habit makes it effective for creating informal drifts or softening the edge of a larger perennial bed, and occasional removal of older stems will keep the clump vigorous while preserving its summer flowering display.
