Allium aflatunense is a 36-inch-tall (0.9 m) bulbous perennial plant with basal, straplike leaves, and hollow, slightly ribbed scapes (flower stems). The flower heads are dense, globular umbels, about 4 inches (10 cm) across, made up of numerous star-shaped, purplish-pink flowers. It flowers in May and June, with seeds ripening in August. It is commonly sold as a bulb.

Allium aflatunense is often confused with A. hollandicum.

Allium aflatunense is generally hardy in USDA zones 4–8. The plant is suitable for use as a cut flower. While it prefers alkaline soil, it can tolerate poor soil conditions, as well as part shade (though it does best in full sun).
Allium hollandicum (aflatunense) is hardy throughout the UK but in higher rainfall areas it would be better planted in well drained situations and certainly positioned to get the sun in the late spring and early summer. 

The flowers are generally 60-75cm tall,  the size of an orange in pale purple or deep lilac. Flowering are at their best in June. They can be planted in swarms where the slight variation in size, colour, maturity and height adds to their charm. Grow them where the foliage of other plants camouflages the leaves as they wither (at about flowering time). The pale greens of plants such as Alchemilla, the purples of the hardy herbaceous geraniums or the blues in the late Camassia all compliment their purple colours very well.
