Artemisia arborescens 'Powis Castle' is fit for a King. The RHS seems to agree, for this plant has been awarded an Award of Garden Merit or AGM. Once this Wormwood's feathery, evergreen foliage has been observed, it's easy to see why it has been granted this honour; the foliage ensures that Artemisia arborescens 'Brass Band' turns heads when it's planted in a cottage garden, a costal area or even on gravelled ground. The half-hardy perennial effortlessly combines form with function, for its Mediterranean heritage means that it tolerates hot, dry borders and patio containers exceptionally well. The plant is therefore a fantastic choice for any gardener seeking to add variety, structure and interest to their kingdom. Height: 50cm (1'8). Spread: 50cm (1'8).
