By this time of summer, hydrangeas are in full bloom and their colorful blossoms set off yards across the region. I’ve learned a lot about this flower as I’ve tried to grow them in my own garden. Whites are the most common and their color is genetically predetermined. The other colors are decided by the soil acidity. Pink varieties prefer alkaline soils and the blue to purple shades require the soil to be acidic. Besides a green thumb, you need some knowledge of soil pH to be successful in growing these beauties. I finally got blossoms for the first time this year.
