This dwarf spirea exhibits bronze coloured new growth, changing to gold in summer, and sports showy, pink flowers. The foliage holds its colour well in the heat. An outstanding border plant, tolerant of most soils and light shade.
‘Mertyann’ is best grown in a loamy soil with full to partial sun. Summer flowering spirea will flower with a good flush in late spring, and sporadically during the summer. To promote a second flush of bloom, remove spent flowers by pinching or light shearing. Pruning for shape should be done in early spring to allow the flower buds to form.
