Key plants in The Ripple Effect Raingarden

<i>Carpinus betulus</i> is one of the show stoppers of the garden, symbolising resilience and endurance. It is more able to cope with temporary water logging than many other tree species, which is one of the reasons it is central to the design.

<i>Hydrangea quercifolia</i> is an attractive deciduous shrub for moisture-retentive soil. It has large oak-like leaves that turn a reddish-purple in autumn, and conical white flowers which take on a rose pink tinge as they mature.

Rodgersia is a moisture-loving plant with palm shaped bronze-green leaves and attractive sprays of white or pink flowers in late summer.

Deschampsia cespitosa is one of the ornamental grasses used in the garden. It has deep green narrow leaves which fade to a golden brown, and long lasting silvery-brown flowers, which add a shimmering effect to the planting. It prefers a moist but free-draining soil, but can tolerate temporary water logging and dry periods.

Lobelia x speciosa is an upright perennial with striking spires of velvety flowers in a range of vibrant, jewel-toned colours. It is long-flowering and prefers a sunny spot with damp soil.
