Graskop Agapanthus

Agapanthus inapertus 'Graskop'

This extraordinary Agapanthus with its compact head of dark violet blue flowers is a garden standout! The buds emerge almost black and are held erect atop tall stems, slowly elongating and finally becoming pendulous as they open. Makes a good container plant and its bright green, strap-like foliage offers great texture when planted in small groupings in the landscape.
