About this plant
Spiraea thunbergii 'Ogon' produces small white flowers along slender stems in early spring, appearing before or as the foliage emerges and creating a soft, airy display. Fine, thread-like leaves open a bright golden yellow, forming delicate, feathery layers that follow the arching structure of the branches. The foliage maintains its luminous tone through the season, while the flowers are spaced along the stems in a light, evenly distributed pattern that enhances the plant's graceful form.
Originating from a species native to Japan and China, this cultivar reflects selection for golden foliage and elegant branching. It is well suited to borders, slopes, and informal hedging, where its early bloom and flowing habit contribute movement and seasonal interest.
Works well in
Sun Gardens · Slopes & Banks · Borders · Pollinator Gardens
Companion plants
Irises · Peruvian lily · Aster · Pampas grass · Stonecrop · Fothergilla
Design tip
Pair ‘Ogon’s’ fine golden foliage with plants that have larger, deeper green leaves, creating contrast in both color and texture. The combination emphasizes its feathery character throughout the growing season, long after the early white flowers have disappeared.
