Herbaceous Perennials for Acid Soil

Bleeding heart is a popular garden perennial that prefers acidic soil.

Some people enjoy warm weather with a beach view, while others prefer snow and mountains. Likewise, some types of plants perform better when their preferences are met, particularly regarding the acidity of the soil in which they grow. Plants preferring alkaline soil will not thrive in an acidic environment and vice versa. If you know your soil tends to be acidic, knowing which plants prefer a lower pH is useful for ensuring a successful garden.

About Soil Acidity

Soil acidity, or the measure of hydrogen ions in a given sample, can be determined by a pH meter or soil sample test. Most home improvement stores and garden centers have simple pH meters available intended for home testing. Highly acidic soils will have a lower pH, from 1.0 to 6.0, while alkaline soils have a high pH, from 8.0 to 11.0. A wide range of plants prefer neutral, or pH level 7, to slightly acidic soils. Overly acidic soils can be adjusted towards neutral by incorporating lime compounds and alkaline soils can be adjusted in the other direction using nitrogen fertilizers, sphagnum peat moss or aluminum sulfate.

Flowering Perennials

Flowering plants which prefer acidic to slightly acidic soils include garden favorites like bleeding heart (Dicentra spp.), creeping phlox (Phlox stolonifera) and most types of daylilies (Hemerocallis spp.). Less well-known but worth consideration for acidic soils are plants including crested iris (Iris cristata), butterfly weed (Asclepias tuberosa), Japanese iris (Iris ensata) and false indigo (Baptisia australis).

Ferns and Groundcovers

Except for Christmas (Polystichum acrostichoides) and maidenhair (Adiantum pedatum) ferns, a good number of ferns prefer slightly acidic sites, including tall stately ostrich ferns (Matteuccia struthiopteris), cinnamon fern (Osmunda cinnamomea), and the smaller, lacier, lady fern (Athyrium filix-femina). Suitable groundcovers include partridgeberry (Mitchella repens), wintergreen (Gaultheria procumbens), scotch heather (Calluna vulgaris), grass-like sedges (Carex spp.) and even oregano (Origanum spp.)

Cuttings are clones

The term clone is used in horticulture to mean all descendants of a single plant, produced by vegetative reproduction or apomixis. Many horticultural plant cultivars are clones, having been derived from a single individual, multiplied by some process other than sexual reproduction. As an example, some European cultivars of grapes represent clones that have been propagated for over two millennia. Other examples are potato and banana
