Easily grown in average, medium, well-drained soil in full sun. Needs full sun for best flowering, but will tolerate very light shade. Prune to shape after flowering.
A densely rounded, deciduous shrub growing 5-8' tall with a slightly larger spread. Primarily grown for its elliptic to obovate, soft chartreuse foliage (to 4" long) and its profuse, funnel-shaped, deep red flowers. Bloom occurs singly or in clusters along the branches of the previous year's growth, frequently covering the entire shrub with flowers in June-July, with a less showy, intermittent repeat bloom sometimes occurring throughout the remaining summer. 'Olympiade' is synonymous with 'Rubidor'.
No serious insect or disease problems.
Effective when grouped in the shrub border. Also useful as a screen, hedge, background or foundation plant. Unusual chartreuse foliage gives this weigela good specimen or accent value.
