Allium ‘Miami’ (Ornamental Onion)

Allium ‘Miami’ is a striking bulbous perennial with star-shaped, deep reddish-purple flowers packed into dome-shaped umbels. Blooming in late spring and early summer, the flowers are borne on tall, upright stems well above the foliage of glossy, strap-shaped leaves. Rich in nectar, the flowers attract bees, butterflies, and other pollinating insects. If left in the garden after the flowers have faded, the seed heads will remain ornamental and add months of interest. They also make excellent cut flowers too. Easy to grow, carefree, deer and rabbit resistant, this Allium is a pretty addition to the garden.

• Growing up to 36-40 in. tall (90-100 cm), this beauty naturalizes easily and will come back year after year!
• Easily grown in fertile, dry to medium moisture, well-drained soils in full sun. Add grit when planting in clay soils to improve drainage. This Allium is drought tolerant.
• Known for attracting bees, butterflies, ​moths, and other pollinators, but deer ignore it.
• Stunning in beds and borders, and cottage gardens. Spectacular in large sweeping drifts. Plant in groups (at least 10 to 15 bulbs) for the best visual impact. Excellent as cut flowers for both fresh and dried arrangements!
• Mixes beautifully with other late spring flowering bulbs and creates stunning combinations with pink or white delphiniums, peonies, or irises.
• No serious pest or disease issues. Keep an eye out for onion white rot and downy mildew.
• To be planted in fall.
• Propagation: remove offsets in fall.

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 just perfect for a rock garden, and several lend themselves to naturalizing. All species can be used in the border.
