About this cultivar:
Spiraea japonica [Magic Carpet] = 'Walbuma' (v) is a low-growing, compact, deciduous shrub with flat clusters of deep pink flowers in summer. Its ovate leaves open red, and mature to various types of yellow depending on the conditions. In full sunlight, mature leaves are golden; under partial shade, mature leaves are greenish gold; and in dense shade, mature leaves are bright green. Tho, it always seems to have some red leaves in there somewhere! Autumn colour a rich ruddy red russet.
It was bred by David R. Tristam of Walberton Nursery in West Sussex, selected from third generation seedlings of self-pollinated Spiraea japonica 'Goldflame'. David did a good job, it has the Royal Horticultural Society Award of Garden Merit! Love it!

About this genus:
Spiraea is a genus of about 80 to 100 species of shrubs in the Rose family (Rosaceae). They are native to the temperate Northern Hemisphere, with the greatest diversity in eastern Asia. The genus formerly included the herbaceous species now segregated into the genera Filipendula and Aruncus; recent genetic evidence has shown that Filipendula is only distantly related to Spiraea, belonging in the subfamily Rosoideae. The genus name comes from the Greek word speira meaning wreath in reference to the showy flower clusters seen on most plants in the genus.
Spiraea plants are hardy, deciduous-leaved shrubs. The leaves are simple and usually short stalked, and are arranged in a spiralling, alternate fashion. The many small flowers of Spiraea shrubs are clustered together in inflorescences, usually in dense panicles, umbrella-like corymbs, or grape-like clusters. These showy clusters of dense flowers make them great for gardens! Some species bloom in the spring, others in midsummer, so do check.
In the garden they will grow anywhere that isn’t too extreme so are always worth a try. Usually grown as stand alones shrubs, some people also grow then as, and into, hedges.
In terstingly, acetylsalicylic acid was first isolated from Filipendula ulmaria, a species at the time classified in the genus Spiraea. The word "aspirin" was coined by adding a- (for acetylation) to spirin, from the German Spirsäure, a reference to Spiraea.
Native American groups seemed to know this – many had various medicinal uses for local Spiraea species. S. betulifolia was used for abdominal pain and made into a tea. The Blackfoot used S. splendens root in an enema and to treat venereal conditions. Many Native Americans found S. douglasii useful for making brooms and hanging seafood to cook as well! Hopefully the beautiful look of these plants is enough to keep you happy and pain-free!
