Blue hydrangeas are timeless classics - but they don't always perform like you'd hope they would, especially if you live in a cold climate. Let's Dance Rhythmic Blue hydrangea from Proven Winners ColorChoice Shrubs changes all that! Early summer brings big, beautiful, blue blooms, and the flowers continue to appear through summer and into autumn. Each floret that makes up the large mophead blooms has a distinctive rectangular shape that makes them look as though they were created by an origami master. 

What makes Let's Dance Rhythmic Blue different from other reblooming bigleaf hydrangeas?

• One of the best true-blue rebloomers

Details:
Name: Hydrangea macrophylla 'SMHMES14' pp#25,836, cbr#5126
Hardiness: USDA zones 5-9
Height x width: 3-4'
Light: Full to part sun
Soil: Evenly moist but well-drained soils are best. A 2-3" layer of shredded bark mulch is recommended in all areas, all year round.
Pruning: Blooms on old and new wood; do not trim or cut back, but dead wood may be removed in early spring
Water: Average to high water needs. Though big leaf hydrangeas cannot grow in wet soils, they can become drought stressed readily and should be watered regularly. Plants in full sun and/or warmer climates will need more water than those in less sun and/or cooler areas. 
Fertilizer: Fertilize once in early spring with a rose fertilizer if desired.
Bloom time: Midsummer through fall.
Bloom color: Though "blue" is in its name, the flower color of Let's Dance Rhythmic Blue hydrangea nonetheless depends on the chemistry of the soil it's growing in. It will be a beautiful true blue in acidic soils that contain aluminum, and bright pink in neutral to alkaline soils. 
Uses: A classic choice for including in gardens and landscaping, it also makes a nice choice for low hedges and containers.
