It is obvious why Spiraea x cinerea ' Grefsheim' has been awarded the coveted RHS AGM! This deciduous shrub is simply amazing in late April & early May, when the ' Bridal Wreath' Spirea is covered in a mass of white flowers. They are set off against a backdrop of grey-green leaves & the stems adopt a graceful, arching habit. Easy to grow, this plant makes a wonderful specimen & it's great for biodiversity too as the flowers attract beneficial insects & the stems & foliage provide cover for birds.
