Ogon Spirea

Ogon Spirea (Spiraea thunbergii 'Ogon')

Ogon Spirea (Spiraea thunbergii 'Ogon') is an early-blooming deciduous shrub celebrated for its soft, arching habit, golden-yellow foliage, and clouds of white spring flowers. Also known as Mellow Yellow Spirea or Thunberg Spirea 'Ogon', this variety adds delicate texture and warm color to the landscape, making it an elegant focal point in early-season borders and naturalistic gardens.

Distinctive Features

This fine-textured shrub grows 3 to 5 feet tall and wide, with narrow willow-like leaves that emerge golden-yellow in spring and gradually mature to a softer chartreuse in summer. In early to mid-spring, before the foliage fully develops, the branches are covered with small white flowers, creating a luminous, lace-like effect. Its graceful arching habit and soft color palette offer year-round ornamental value.
