Magic Carpet Japanese Spirea

Spiraea japonica 'Walbuma'

Plant Details:

Plant Type: Shrub
Plant Family: Rosaceae
Plant Description: Small, rounded deciduous shrub. Produces abundant flat clusters or rose pink flowers in mid to late spring into the summer. Young leaves emerge reddish bronze. Depending on the amount of shade Walbuma is in, mature leaves will range from golden yellow to bright green. Requires significant pruning to promote more flowering.

Maintenance:

Maintenance Type: Shrub - Hard Pruning
Plant Care: Shrub - Hard Pruning (woody multi-stemmed plants that lose their leaves every winter and look best on one year of new growth): Cut down all branches to the base of the plant every year in the late winter or early spring, leaving a few inches with buds to regrow. Monitor for pests, diseases, or other ailments on a regular basis.
Special Considerations: This particular shrub does not need this hard pruning done every year. It can be done every 2-3 years, or as needed. This will keep it from looking weedy or leggy.
