Spiraea thunbergii 'Ogon' - Gold Thread™ Spirea, Mellow Yellow Spiraea

Gold Thread Spirea (also known as Mellow Yellow Spiraea) is a delightfully airy deciduous shrub that brings year-round color and movement to the garden. Its fine, willow-like leaves emerge in a warm yellow-green in spring, mature to bright green through summer, and then transition to a stunning coral orange in fall — offering three distinct seasons of foliage interest.

In spring, flat-topped clusters of pure white flowers blanket the plant in a frothy, cloud-like display that’s hard to miss. Deadheading spent flowers encourages additional blooms, extending the season even further. It grows best in full sun with well-drained soil and has a graceful, twiggy upright arching habit that adds texture and softness to any planting.

Compact and easy to care for, Gold Thread Spirea is a versatile performer in borders, mass plantings, and cottage-style gardens.

Ideal for: Mixed borders, mass plantings, cottage gardens, and multi-season color.
