Hydrangea macrophylla ‘Möwe’ is at its best grown in alkaline soils to achieve deep red ray florets. Usually depicted in all the major hydrangea textbooks with deep red flowers, we have found this difficult to achieve in our acidic soils of southern British Columbia. It is equally attractive with its pale blue to mauve flowers.
A deciduous, vigorous, spreading shrub with large, vibrant green foliage. Blooming from early summer to autumn. A great plant for shady or partly shady situations.
Inflorescence: Lacecap, 200mm across. Corymbs are flat lacecaps, pale pink or pale blue depending on availability of aluminium ions in the soil.
synonym: H. m. ‘Geoffrey Chadbund’. ‘Möwe’ translates to ‘Seagull’.
Bred by Federal Research Inst for Horticulture, Wädenswil, Switzerland, in 1964.
