Description

Introduced by our National Arboretum, 'Nikko' features profuse, double white flowers that last up to two weeks in spring, covering its compact form. 'Nikko' thrives in rich, well-drained soil, plenty of sun, and with a good pruning after flowering. Plant it in groups in amongst perennials, along a foundation or in a small border area for a goregous late-spring display of blooms.
