Agapanthus 'Northern Star' is very free flowering, forming masses of umbel flower heads all through summer. The stunning deep blue flowers have a purple stripe the same as the purple base of the semi-evergreen foliage. A tall African Blue Lily, ideal in the middle of your garden's border and planted in large clumps so the blooms rise above the other hardy perennials. Agapanthus flowers are also superb for cutting - if you can bear to! Height: 90cm (35). Spread: 45cm (18). A truly exquisite variety!
