The Sunken Garden
A hardy clump-forming ornamental onion, from North America, 30cm in height, that has very narrow leaves and produces loose umbels of nodding, long-stalked, pink bell-shaped flowers in early summer. It is a vigorous grower and spreads quickly. Similar to A.macanthum its Asian cousin but less than half the twice the size and its slender bulbs look more like rhizomes than bulbs.
Site and Care:
Plant 5cm to 10cm (2in to 4in) deep in autumn, in moist but well-drained soil, of any type, in a sunny position. Divide between February and April.
