'Ogon' Spiraea (Mellow Yellow)
Spiraea thunbergii 'Ogon'
Flower: Clusters of white flowers
along the stems in the spring before the foliage emerges.
Size: 3-5' in height and 3-5' in width. Very vigorous growth in the spring each season.
Foliage Color: Bright yellow or gold in the spring, fading to a yellow-green color in late summer. The thin leaves have a willow-like appearance. Reddish fall color.
Hardiness Zones: 4-8
Light Requirement: Full sun to part-shade. Part-shade is best, because the foliage is susceptible to being scorched by direct summer sun.
Drought Tolerance: Moderate to High.
Notes: The bright yellow willow-like foliage is very nice on 'Ogon'. Great plant for planting in large groups. Tolerant of most soil types. This variety is also sold as 'Mellow Yellow' Spiraea.
