Description

Hydrangeas are deciduous shrubs with flowers in terminal, round or umbrella-shaped clusters in colors of white, pink, or blue, or even purple. If they flower blue, your soil is acidic (having less than 5.5 pH) and if they bloom pink, your soil is alkaline (higher than 6.5 pH).  If your soil is between acidic and alkaline, then you will probably have purple flowers.
