Acid-loving plants and shrubs are those that thrive in soil with a pH level of around 5.5. Due to the low pH level, the plants are able to absorb nutrients that are necessary for growth.
Before growing acid-loving plants, check the pH level of the soil to determine whether or not it needs to be treated with acid. In general, the Pacific Northwest and the eastern side of the United States, provide hospitable environments for acid loving plants.
Astilbe, bergenia, bleeding heart, foxglove, heath and azaleas are examples of commonly grown acid-loving plants and shrubs. Although the plants thrive in the acidic soil, when planting, be sure to take note of the other specific conditions that will help the plant the flourish. For example, heath is a shrub that grows year-round and begins flowering in late winter. The shrub prefers to grow in full sun and needs to be planted on a site with ample drainage as standing water can kill it. In contrast, bergenia, which boast red or white flowers atop of up to 18 inches high stalks, grow best when partially in the shade. Although they bloom in the full sun, the leaves burn easily, so it is a careful balance. Bergenia require lush soil and the soil needs to be consistently moist.
