I saw a similar question on this but it still did not answer my question. I have a hydrangea that is about 5 years old and is about 3-4 feet tall, 3 feet wide and the leaves are green and healthy but no flowers. I was told that flowers buds are formed on this years new growth for next year and here in Michigan the winters might be freezing those new flower buds. Is this true and what variety would do well here. Is there a hydrangea that blooms on this years growth?

If you have a big leaf hydrangea (Hydrangea macrophylla), it blooms on new shoots that develop on old wood. If the plant regularly dies down to the ground each winter, there will be no old wood and therefore no flowers. A better choice for your area is Endless Summer. Endless Summer is a perpetual flowering big-leaf Hydrangea that blooms virtually all season long. And because Endless Summer can flower repeatedly on new wood, you can be confident that regardless of whether the plant dies back to the crown or is trimmed at the wrong time, you'll still get wonderful flowers that grow all season.

What makes Endless Summer even more appealing is that it is remarkably hardy, even to Zone 4. What's more it's proven to be more mildew resistant than other macrophylla varieties.

You won't be disappointed if your replace your non-blooming hydrangea with an Endless Summer!
