Noteworthy Characteristics

Spiraea thunbergii is a dense, twiggy, upright, multi-stemmed, deciduous shrub with wiry, outward-arching branching. It typically grows 3-5’ tall and as wide, often becoming somewhat open and leggy over time. 'Ogon' is a golden-leaved variety. Narrow, linear-lanceolate, sparsely-toothed leaves (to 1.5" long) emerge golden yellow in spring, mature to bright green in summer and finally turn interesting shades of orange in fall. Leaves have a willow-like appearance. Golden spring foliage color gives way to chartreuse-green if plants are sited in part shade conditions. Tiny, 5-petaled, white flowers (each of 1/3" diameter) in 3- to 5-flowered umbulate clusters bloom in early spring before the foliage emerges. Specific epithet honors Carl Peter Thunberg (1743-1828), Swedish plant explorer, who introduced species plants to Europe.

Problems

No serious insect or disease problems. Susceptible to many of the diseases and insects that attack other rose family members, including leaf spot, fire blight, powdery mildew, root rot, aphids, leaf roller and scale.

Garden Uses

Foundations, borders, sunny woodland margins. Interesting specimen.
