Where do i find Hydrennias?

They're blue-colored flowers. Normally a bush. Don't know where to buy. Any ideas?

Where do i find Hydrennias?
Hydrangeas are pretty common. Home Depot and Lowes usually have them, and most plant nurseries will as well. It's true that you need either naturally acid soil, an acid fertilizer, or another source of acidifier (this means lowering the pH level of the soil) if you want blue blooms. I know that the pink bloomed ones will bloom blue in an acid soil, but I'm not sure that the white ones will.

Reply:Hydrangia:

Can be found at most garden centres and some florist shops.

They are later blooming in garden - Large white flowers.

Anabelle and Pegee are two large white favourites.

Add an acdic solution to the soil to make the flowers blue
Reply:They are called Hydrangeas and you can find them at your local garden center/nursery. Make sure you buy the kind that is hardy in your area as there are "florists varieties" that only live indoors in most areas.
