Botanical description
Allium sphaerocephalon is a perennial bulbous plant belonging to the Amaryllidaceae family. It typically grows to a height of 15-80 cm. The plant has cylindrical, hollow leaves. The inflorescence is a dense, spherical umbel composed of numerous small, purplish-red to reddish-purple flowers. The flowers bloom in summer. The bulb is ovoid and about 1-2 cm in diameter. It is native to Europe and Western Asia, and it is found in dry grasslands, meadows, and rocky slopes.
Companion planting
Like other alliums, it may deter pests like aphids, cabbage white butterflies, and carrot root flies. It is a good companion plant for roses, tomatoes, carrots, and chamomile. Avoid planting near beans and peas, as alliums can inhibit their growth.
Propagation methods
Propagation is typically achieved through bulb division in the fall or spring. It can also be propagated by seed, though germination can be slow. Offsets can be carefully separated from the main bulb and replanted.
