I have several Goldmound Spirea’s grown mostly for their bright yellow-green foliage colour. They make a great accent plant and are good massed. I have several that are now about 30 inches high and 3-4 feet across. The actual size depends on whether or not you prune them back in late July.
A great low maintenance shrub, Spirea Goldmound does not really need to be pruned in summer if you don’t want to. I usually prune mine each spring prior to or just as they are leafing out for shape and size. I prune some again after they have bloomed in July and leave some unpruned (mostly those in the outer gardens). The dead flowerheads on Goldmound are pale enough that they do not really detract from the appearance of the plant. For specimen plants deadheading does make the plant look better and you will be rewarded with a second flush of blooms in late summer. If you do prune in July the foliage will be a bit more on the lime-green side until the sun turns new growth yellow.
The flowers are light pink, appear in mid-summer and have a frothy airy appearance. They largely fade into the brighter foliage are are not the main attraction of this shrub.
Fall foliage can provide steaks of orange and reds amid the golden foliage.
As with all summer blooming spireas, Goldmound needs a heavy pruning two or three times their first two seasons. They grow so fast they are a bit leggy the first and sometimes second season so pruning keeps them bushy and in shape but I have found by the third season they generally keep the nice mounded shape on their own.
Garden Locations: Kitchen Patio Garden, Bird Sanctuary Garden, East Garden, Woodland Garden. Most are mass planted, often curving around larger shrubs such as Euonymus alatus (Burning Bush) or Red Prince Weigela.
