Quick facts

Top plants for sinks and troughs

Introduction

Creating just the right conditions to grow alpine and rock plants is the first stage. The next stage and most enjoyable, is choosing the plants. You could select plants for the longest flowering over the year, or you might choose a genus of plants for specific conditions, such as lewisias. Aim to choose variety in texture of foliage as well as flower.

Practical considerations

Ensure that the sink is placed in the ideal conditions for the plants. An open sunny position is ideal.

Planting up sinks and troughs and making them from scratch is explained in our sink and trough gardening page.
