Plants for acid soils with bursts of yellow
Plenty of plants thrive in the lower pH of acidic or ericaceous soil, so it’s perfectly possible to create a full and attractive border even in these sometimes challenging conditions
Quick facts
- For some plants, acidic soil is essential for them to thrive – these are often referred to as ericaceous plants
- Acid conditions are produced by the underlying rock type, which is outside of gardener control, so it’s best to use plants that naturally prefer these soil conditions

The planting plan
This planting design provides a range of plants with splashes of yellow that, once established, will thrive in acidic soil and provide colour and interest throughout the year. A simple planting plan helps to create depth, interest and good coverage in a border.
Choosing plants for acid soil
These plants have been selected because their preferred growing condition is acidic soil. By using plants that are naturally adapted to these conditions, we can enjoy healthier plants and lower inputs compared with trying to grow plants that are less well suited.
The Epimedium and Gentiana provide some groundcover and will help prevent erosion of bare soil. The groundcover can also help to reduce evaporative moisture loss from the soil surface, and suppress weed growth.
Additional organic mulching, preferably with homemade compost, can further improve soil moisture retention and weed suppression. Mulches should be spread when the soil is already moist, to help trap some of that moisture before it dries out in summer.
2 - Hamamelis x intermedia ‘Arnold Promise’ is a large, spreading, open shrub. The green leaves turn red and yellow in autumn, and fragrant, bright yellow flower tassels festoon the bare stems in late winter.
3 - Epimedium x warleyense is a hardy perennial forming a spreading evergreen mound of divided leaves, held on thin wiry stems. These often have strong red tints, especially when young. It bears sprays of coppery red and yellow flowers in spring.
4 - Gentiana ‘Strathmore’ is a mat-forming herbaceous perennial with narrow green leaves and sky-blue, funnel-shaped flowers with paler stripes in autumn.
5 - Gaultheria mucronata ‘Bell’s Seedling’ is a small, dense evergreen shrub with tiny dark leaves and clusters of small white flowers in late spring and early summer. These ripen into dark crimson berries in autumn.
6 - Corylopsis pauciflora is a deciduous shrub with green leaves that are tinged red when young. It has fragrant, pale yellow, bell-shaped flowers, which open before the leaves in spring.
