20 Reliable Plants That Grow Well in Acidic Soil and Look Great Too
American Holly (Ilex opaca)
The American holly shrub is often associated with the winter holiday season, but its uses extend far beyond festive decorations. This versatile broad-leafed evergreen can serve as a functional hedge for privacy and wind screening while also offering ornamental appeal.

Not only do Caladium plants offer an explosion of color, but they’re also well-suited for areas with acidic soils. Additionally, they thrive in warm environments, tolerating hardiness zones nine and warmer. This means that many regions throughout the United States will need to bring these tropical wonders indoors during the chillier months of the year.
Camellia (Camellia japonica)
Camellias’ breathtaking beauty is a challenge to adequately describe, particularly when it comes to their showstopping flowers.

But its practicality isn’t its only notable feature; the oakleaf hydrangea also boasts a striking appearance, with large, showy flower clusters and deciduous leaves that resemble oak leaves and turn a deep crimson in autumn.
Pachysandra (Pachysandra terminalis)
Pachysandra, a popular choice for residential landscapes, boasts broad leaves and a dense, spreading growth habit that makes it an effective groundcover species. Its ability to quickly cover large areas can sometimes be a challenge, as it will spread rapidly when it finds the right conditions. One of these ideal conditions is acidic soil, which the plant adapts to particularly well.
Rosebay Rhododendron (Rhododendron maximum)
Rhododendron shrubs, like their azalea counterparts, boast an impressive array of varieties. However, none are more prominent than the majestic rosebay rhododendron. This behemoth of a plant features broad, evergreen leaves and produces clusters of snowy white blooms.
