Allium atropurpureum features umbels of burgundy-purple star-shaped flowers that harmonize with late spring blooms. Growing about 2 feet tall, this pollinator favorite creates a beautiful focal point, and will also add a cheerful note to a planting bed when sprinkled among other spring flowers where it can dance in a breeze.

Description

There is something spectacular about Allium’s architectural presence in the garden. Also called Flowering Onion or Persian Onion, Alliums’ unique globe-shaped flower clusters offer the ultimate early summer show. Plant bulbs in fall among perennials, where they will enhance your garden between spring and summer blooms, and where fading foliage will be hidden by growing perennials. Leave flowers standing for visual interest through the fall and winter months. Alliums are favorites of bees, butterflies, and other pollinators. Easy-to grow Alliums are drought tolerant, unappetizing to critters, and are nearly pest-free. They will thrive in the garden and return each spring for years to come.

Planting & Care

Tips on Growing Fall Planted Flower Bulbs

When you receive your fall bulbs (tulips, daffodils, etc.) keep them in a dry, dark, cool place until ready to plant. They need air circulation so they will not collect moisture and rot. Planting times can vary from early October in the North to mid-to-late November in the southern regions. A good rule of thumb is to plant them about 6 weeks before the ground is frozen or after the first hard freeze.

Soil Preparation for Bulbs

A compost-enriched, well-drained soil is best. Incorporate a good quality organic compost as needed. Yum Yum Mix® is recommended as an excellent source of nitrogen, phosphorus, and potassium needed for strong plants and healthy roots. Mix a small amount into the bottom of the hole before planting your bulbs.

Many bulbs prefer full sun exposure. However, Muscaria, Allium, Galanthus, Hyacinthoides, Scilla and many Daffodils will tolerate partial shade and bloom well.
Pink daffodils will hold their color longer if planted in dappled shade or morning sun/afternoon shade.

After planting, add a top dressing of compost or other organic material and water in thoroughly. If your winter is dry, water every three to four weeks throughout the winter and add more mulch if necessary.

Protect your Bulbs

Apply a mole or gopher repellent to the surface of the ground to protect bulbs from these burrowing mammals.

After your Bulbs have Bloomed

Once your bulbs have bloomed, allow the bulb foliage to brown and fade naturally since the leaves are feeding the bulb in the ground. Removal of foliage weakens the bulb and leads to fewer blooms the following year. Planting your bulbs amongst your perennials is one way to conceal the dying bulb foliage. The perennials begin to grow and fill out as the bulb foliage dies back. The perennials will then provide foliage and color in the garden from late spring through the summer and into fall. Regular fertilization with balanced organic or natural fertilizer and a re-application of mulch each fall will ensure more and more beautiful spring bulb blooms for many years!
