Allium nutans: complete guide

Overview

Allium nutans, commonly called blue chives or Siberian garlic chives, is an intriguing garden plant originating from Siberian steppes. This culinary plant leads a double life - serving as both food crop and ornamental. With its unique blue flowers it stands apart from most other allium species.

The plant reaches 30 to 50 centimeters in height, blooming July through August with brilliant blue-violet flowers. It is hardy to extremely low temperatures and tolerates dry climates better than most other edible allium species.

Appearance and bloom

Allium nutans grows from small underground bulbs with flat, gray-green leaves reaching 15-25 centimeters long. The leaves have an interesting flattening - semi-cylindrical but not completely hollow. This is a characteristic feature distinguishing it from other alliums.

Flowers appear July through August on stems 30-50 centimeters tall. The inflorescence is compact and ball-shaped, with twenty to thirty small blue-violet flowers. This color is striking - many allium species are white or pink, so the blue tint is rare and valuable.

After blooming, seed capsules form which are also quirky and decorative. The entire plant is edible and tastes like onion with hints of garlic.

Ideal location

Blue chives thrive best in full sun with minimum 6 hours direct sunlight. The plant tolerates partial shade but produces fewer flowers there. The location must be well-drained - wetter soils are not appreciated.

Plant in borders, along pathways, or in groups for maximum visual effect. The compact growth makes it suitable for small gardens. It combines beautifully with Mediterranean herbs and lavender.

In the kitchen it can grow or in special herb gardens. Many gardeners grow it both for ornament and food.

Soil

Blue chives is undemanding and accepts various soil types. Sandy, loamy and even rocky soils are suitable. pH between 5.5 and 7.5 is ideal.

Good drainage is important. In heavy clay, add sand and compost. The plant thrives in poor soils. Excessive feeding can lead to more leaf growth at the expense of flowers.

Plant bulbs 5-7 centimeters deep and 8-10 centimeters apart. When planted in groups they create strong visual effects.

Watering

Once established, blue chives is quite drought tolerant. Water regularly the first year to establish roots. Subsequently it requires very little water.

Even in Mediterranean gardens and dry climates it grows well. Extra water during very dry periods helps but is not essential. Avoid waterlogging.

After blooming no water is needed. The plant goes dormant.

Pruning

Minimal pruning needed. Spent flowers can be removed or left for seed. If you harvest the plant for food, pluck leaves as needed.

Allow dead material after blooming to stand until the plant yellows. This helps nutrients return to the bulb.
