Artemisia x 'Powis Castle' is a hardy, bushy, low growing shrub that has very attractive, soft, silvery grey, deeply divided foliage.
This cultivar rarely produces tiny yellow flowers, so it's valued for its silvery, scented foliage that looks great as an edging plant or for texture and colour foliage contrast.
It will grow to full size in one season and makes an excellent understorey to taller, flowering border plants
It's also quite drought tolerant, so it's handy for dry climates.
Possibly its greatest asset is a unique ability to send Possums packing - they seem to hate the odour it exudes. Therefore best grown in pots to move around the garden as plant protection is required.
