Snow Day® Surprise Pearl-bush

Snow Day® Surprise pearl-bush (*Exochorda* hybrid ‘Niagara’) is a compact, deciduous shrub known for a heavy display of large white flowers in spring. The [Proven Winners profile](https://www.provenwinners.com/plants/exochorda/snow-day-surprise-pearl-bush-exochorda-hybrid) lists the cultivar and patent identifiers and describes its place in borders and mixed plantings. ## Form and Season Clusters of rounded buds open into white flowers in early to late spring, followed by green foliage. The breeder lists mature height and spread at 3–4 feet, with a broadly upright, mounded habit; its tidy size suits smaller gardens while still creating a noticeable spring display. ## Siting Grow Snow Day® Surprise in full sun or partial shade, in soil that drains well. The breeder describes it as adaptable to most soils, with a preference for well-drained, acidic soil, and rates its water needs as average. It is hardy in USDA zones 4–8 and works well in a mixed border or near a path where the flowers can be enjoyed. ## Maintenance This shrub flowers on the previous season’s growth. If shaping is needed, prune just after flowering so new growth can develop for the next spring display; avoid routine pruning before bloom.
