Allium 'Serendipity' (Ornamental Allium)
A sport of the popular Allium 'Millenium', Allium 'Serendipidity' (Ornamental Allium) is a bulbous perennial boasting profuse, globe-shaped, rosy-purple flowers. Blooming from mid to late summer, they are borne atop sturdy, upright stems just above the attractive foliage clump of blue-green leaves. The foliage has a slight onion scent when bruised. Rich in nectar, the flowers attract bees and butterflies. They make excellent cut flowers. Easy to grow, carefree, deer and rabbit-resistant, Allium 'Lavender Bubbles' is a charming addition to the rock or herb garden.
- Grows up to 15-20 in. tall (37-50 cm) and 10-15 in. wide (25-37 cm).
- Thrives in fertile, well-drained soils in full sun to part shade. Add grit to clay soils to improve drainage. This Allium is drought tolerant.
- Lovely in beds and borders, cottage gardens, and containers. To achieve an impressive visual effect, plant in clusters.
- Known for attracting bees, butterflies, moths, and other pollinators, but deer and rabbits ignore it.
- Generally pest and disease free. Keep an eye out for onion white rot and downy mildew.
- Cut back after flowering or merely remove dead flowerheads.
- Propagate by removing offsets in autumn.
Hundreds of Allium species exist, but only a few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their remarkable diversity in color, inflorescence, and flowering height. Many species bloom in early summer - just after the spring-flowering period and just before the exuberant full bloom of summer. Certain small species are perfect for a rock garden, and several lend themselves to naturalizing. All species can be used in the border.
