Masja is a beautiful upright plant (not spreading out much), that produces medium sized blooms. Pacific NW soils are acid - so the blooms are dark blue to purple. I love including these flowers in a mixed flower bouquet -- they last over a week!

ZONE 7 - Atlanta, GA
I love this hydrangea. The leaves are thick and a glossy deep green, the flowers large and substantial with thick stems that don't droop when heavy with rain. Masja is a majestic flowering shrub and makes a fabulous foundation plant in an area where you don't mind that it is deciduous. They are gorgeous in masse. Here in Atlanta some of my 4 year old Masja are reaching 5 which is much taller than the reported 3. I also have several planted in full sun in an oceanfront location on Amelia Island, Zone 8a, and they are absolutely happy. Soil acidity has had only a limited effect on the flower color. Deep pink (slightly tinged with purple in our acid Atlanta soil) with cobalt blue central Anthers, the blooms are more than impressive and very long lasting. ... read more

According to the authors of "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press), " Low compact shrub to 3'. Flowerheads perfectly rounded, very uniform warm red in alkaline to rich blue/purple in acid soil. Frequently flowers twice a year. Very suitable as a pot plant. A sport of 'Alpengluhen'. Similar or identical to 'Sibylla', 'Sybilla'.

Other notes: not particularly cold hardy. No zone given.
