Your Bailday hydrangea produces flowering shoots from old wood. So, pruning is important. Prune the old canes back to about 18" above ground level in the late winter or early spring. New shoots which develop from the old wood should flower for you. Hydrangeas prefer to grow in morning sun with afternoon shade. If your hydrangea is not getting a few hours of morning sun, this might cause it to grow lush and green, but not flower.

Best wishes with your hydrangea!

Are there really no comments or questions on this plant for 12 years???

Plant is no longer in commercial production, so that will limit info.
btw, the pruning advice provided in the first answer is grossly inaccurate!! Pruning of non-remontant or old wood flowering bigleaf hydrangeas - such as Light O' Day - should be undertaken with a very light hand, if at all. Pruning everything back to 18" will pretty much guarantee no flowers as all the latent flower buds will have been removed. Flower buds are formed at the terminal ends of the stems, not down low!!

I just bought mine last summer and live in Columbus, Ohio. We've had our first few frosts and my Light of Day looks to be in sad shape. All brown. Should I just let them come back in the spring? Thanks for your help gardengal48. BTW my email is [email protected]
