ALLIUM stipitatum 'Mars'
Tall Ornamental Onion
One of a host of ornamental onions hailing from Central Asia, Allium stipitatum bears large globular heads of purple flowers on tall stems in late spring. The flowers of the cultivar 'Mars' are an especially deep lavender purple. The long, strap shaped, grayish-green leaves wither as the flowering stems appear. The leaves, stems, and bulbs carry the typical "onion scent".
Plant the bulbs in autumn at a depth three times their height in fertile well-drained soil and full sun. Lift and divide the clumps only when they become crowded. Plant this ornamental onion wherever you want an exclamation point in the garden, and in groups for maximum impact. It is effective in the mixed border, large alpine bed, or rock garden. The cut flowers are long-lasting and dry well.
