Acid loving plants prefer a soil pH of about 5.5. This lower pH enables these plants to absorb the nutrients they need to flourish and grow. The list of what type of plants grow in acidic soil is extensive. The following suggestions are only a few of the most popular plants that need acid soil. Generally, the eastern half of the United States and the Pacific Northwest are best for plants that need acid soil.
Before asking what types of plants grow in acid soil, check your soil pH. A neutral soil can be treated with acid producing materials to lower the pH enough to satisfy acidic soil flowers. If you live in an area where soil is alkaline, it will probably be easier to grow your acid loving plants in containers or raised beds.

No list of what type of plants grow in acid soil would be complete without the hydrangea. Bright blue flower heads cover the plant when the soil is acidic.
