Choosing the Right Allium for You
The first step in your allium journey is selecting the right varieties. With over 900 species, you’ll find alliums ranging in size from petite, ground-hugging varieties to towering giants reaching several feet tall. Consider the following factors:
- Flowering Time: Allium bloom times vary, offering a staggered display of color throughout the growing season. Early bloomers like ‘Purple Sensation’ and ‘Globemaster’ herald spring, while late-blooming varieties like ‘Mount Everest’ and ‘Ambassador’ grace the garden in summer.
- Flower Color: Allium flowers come in a spectrum of hues, from the classic purple and white to vibrant pink, yellow, and even blue. Choose colors that complement your existing garden palette.
- Height: Tall varieties like ‘Globemaster’ and ‘Ambassador’ create dramatic focal points, while shorter varieties like ‘Purple Sensation’ and ‘Millenium’ are ideal for borders and container plantings.
- Growing Conditions: While most alliums thrive in full sun, some prefer partial shade. Consider your garden’s conditions when making your selection.
Planting Allium Bulbs
The best time to plant allium bulbs is in the fall, typically from September to November. This allows the bulbs to establish roots before the winter freeze. Here’s a step-by-step guide to planting allium bulbs:
1. Choose a Suitable Location: Select a sunny spot with well-drained soil. Alliums are adaptable, but they prefer soil with a pH between 6.0 and 7.0.
2. Prepare the Planting Area: Dig a hole twice the width and depth of the bulb. Amend the soil with compost or aged manure to improve drainage and fertility.
3. Plant the Bulbs: Place the bulb in the hole with the pointed end facing upwards. Cover the bulb with soil, ensuring the top of the bulb is level with the soil surface.
4. Water Thoroughly: After planting, water the area deeply to settle the soil around the bulbs.
Caring for Your Allium Plants
Once planted, alliums require minimal care. Here are a few tips to ensure healthy growth and vibrant blooms:
- Watering: Water regularly during the growing season, especially during dry spells. Avoid overwatering, as this can lead to root rot.
- Fertilizing: Apply a balanced fertilizer in the spring to encourage strong growth and abundant blooms.
- Mulching: Mulch around the plants in the spring to conserve moisture and suppress weeds.
- Deadheading: Remove spent flower stalks to promote tidy growth and discourage self-seeding.
- Dividing Bulbs: Every few years, you can divide the bulbs to create new plants. Dig up the bulbs in the fall and gently separate the smaller bulbs.
Harvesting and Preserving Allium
Many allium varieties, like chives and garlic, are edible. Here’s a guide to harvesting and preserving your allium bounty:
- Chives: Harvest chives by snipping the leaves with scissors or a sharp knife. You can harvest leaves throughout the growing season.
- Garlic: Harvest garlic bulbs when the leaves turn brown and begin to die back. Dig up the bulbs and allow them to dry in a cool, dry place.
- Onions: Harvest onions when the bulbs are firm and the leaves are dry. You can store onions in a cool, dry place for several months.

Allium’s versatility extends beyond their edible qualities. Their striking flowerheads, available in a range of colors and sizes, make them a valuable asset in any garden design. Here are some creative ways to incorporate allium into your landscape:
