Plants That Thrive on Acidic Soil

Soil can have pH values of alkaline, neutral or acidic. Certain plants are designed to thrive in all types; however, if a plant cannot tolerate its soil, it is destined to fail. Don't go through the hassle of trial and error. Always test the soil before planting, and if its acidic, choose plants for that type of soil.

The plant grows 1 to 2 feet tall with flowers 3 to 4 inches wide in blue, pink, white or lavender. Plant in acidic soil that hasn't had lime added. Full sun is needed with plenty of waterings.
