Trailing plants like aubretia are great for a rockery
Dot your alpines around the rocks. My two favourites are sedums and saxifraga, but there are dozens of varieties available.
The break up the rockery with other plants to add different heights and textures. Try thrifts, sedges, rock roses, dwarf conifers and ornamental grasses. My favourite is Morning Star Deep Rose, which has rich pink flowers that contrast nicely against the grey stones.
You can also throw in some early spring and summer bulbs to add height and extra colour and scent to your rockery. Try crocus, iris and dwarf reticulata.
