The Allium 'Lucy Ball', 'Allium', a fall planted ornamental onion bulb, will produce large flowers. This award-winning variety has sweetly scented, dark rosy, lilac flower heads, that are tightly packed and sitting at the top of tall, thick, bare stems. They are great for ornamental value and widely used for both landscape and cut flower purposes. The blooms are pleasantly fragrant and this plant is an easy and prolific addition to the garden. Alliums will grow in any average soil, doing even better in rich, well-drained soil. To achieve a successful visual effect, 10 to 15 bulbs should be planted close together. Alliums prefer to be dry in their dormancy.
The Allium Lucy Ball is ideal for containers, mass plantings, borders, and cut flowers. These plants are rabbit, squirrel, and deer resistant. Lucy Ball has a bloom period of about 3 weeks and they bloom in late spring to early summer.
The name Allium is from the ancient name for garlic, which is part of the genus. There are estimated to be around 700 species within the genus, and many cultivars. There are perennials and biennials, ranging in height from 10cm - 1.5m (4in - 5ft) or more.
They are mainly from dry and mountainous areas, all from the Northern Hemisphere, and they have adapted to live in almost every plant habitat on the planet, from ice cold tundra to burning, arid deserts.
Many members of the genus give themselves away with the distinctive smell of onions when the bulb or foliage is bruised.
They have upright to spreading linear-shaped leaves. The tubular based flowers are bell, star or cup shaped which are borne in spherical umbels 1 - 10cm (3/8 - 4in) across.
In most species, a single bulb produces clusters of offset bulbs around it, which gradually form clumps.
Taller species look good in groups in a border. The flower heads dry well. Several species have culinary uses, including A. sativum (garlic), culinary onions, shallots and chives.
The whole group was prized by the ancients as possessing medical and aphrodisiac qualities as well as flavour. The Romans are sometimes held responsible for their wide distribution by taking them wherever they went.
