Gardeners in northern climates have been disappointed  by Hydrangea macrophylla in the past….lots of healthy foliage, but few or no blossoms. This recent introduction of Mophead Hydrangea truly blooms on both old and new wood,  and is being marketed as ‘Forever and Ever Red Sensation’ ( Tra-la-la…those clever marketers read a lot of fairy tales).

What you really need to know is that this vigorous selection produces lots of blooms on new growth, making it a great candidate for colder zone 5 and 6 gardens. In hot climates the large trusses of blossoms will be in softer shades of rosy pink when grown in neutral to slightly alkaline soil. Colder temperatures will cause the flower color to deeper red shades. If your garden soil happens to be more acidic, ‘Red Sensation’ will change color and thus need a new name, as it will take on bluer tones. The flowers age to smoky violet. Stems and fall foliage color have a dark burgundy cast.

‘Red Sensation’ grow 2-3′ tall and 3-4’wide, and require full sun or partial shade. Hydrangea macrophylla appreciate a moist, rich and fertile soil.  May we suggest combining ‘Red Sensation’ with the always attractive Periscaria ‘Golden Arrow’?
