Hydrangea macrophylla 'Blue Wave'
Sorry, this product is sold out!
Hydrangea is without a doubt one of the great family of plants, so many great species. So macrophylla is usually accepted as the stand out species. A slow growing medium sized deciduous shrub, with large flat and very vibrant blue and flowers from early into late summer, macrophylla thrives in acidic and alkaline soil. The flowers look great after blooming too, as the petals dry out and brown up in to a lovely looking structure for the remainder of the year. Prune and dead head the old flower heads in early Spring. Hydrangeas require a lot of water to be vibrant, so do not plant them in dry sites, and new plants will need plenty of regular watering to get them gowing.
