Which ground cover plant goes where?
Creeping thyme, Caucasian stonecrop and the creeping juniper ‘Wiltonii’ belong in the sunniest, driest parts of the garden, where they make do with thin, stony soil, and the juniper also holds the soil on a slope. Lesser periwinkle and bigroot cranesbill, on the other hand, cope with shade, and the cranesbill is one of the few plants that can handle dry shade.
They differ in height too: creeping thyme forms a mat 5-10 cm high, periwinkle, juniper and stonecrop reach 8-15 cm, while bigroot cranesbill grows to 30-45 cm and smothers weeds with its dense, aromatic foliage. Over time the juniper spreads 1.8-4 metres wide, so a single plant can cover a large area.

A fragrant, carpet-forming ground cover for the sunniest, driest parts of the garden that grows even in shallow, stony soil.
In wet, poorly drained soil it suffers from root rot, so don't mulch it.

Creeping juniper 'Wiltonii'
Juniperus horizontalis 'Wiltonii' (syn. 'Blue Rug')
A silvery-blue evergreen that hugs the ground, thrives even on a dry, stony bank in blazing sun, and helps to hold the soil in place.
Harmful if eaten and may cause skin allergies, and junipers can act as alternate hosts for rust diseases of apples and pears.
