This is the Spirea variety Grefsheim that has been growing in my garden for many years and was multiply propagated by a piece of a branch pressed into the soill. This is wonderful to see in late spring - early summer, when its small ball-shaped buds open on one warm night. I go to the front garden and see a white bush that looks like a snow one.
Spirea has a high phytoncide activity, which increases its sanitary-hygienic role in improving the environment.
Do you ever grow spirea in you garden? What variety do you love most?
