Asparagus officinalis 'Stewart's Purple'

An upright, clump-forming perennial grown for its edible, rich dark purple shoots, known as spears, harvested from mid-spring to early summer. Once cropping has stopped, tall, branching stems develop with airy, feathery, mid-green foliage, 1.5 x 1.5m. Small, inconspicuous, green and white flowers may be followed by sparse red berries
