Allium carinatum, commonly known as keeled garlic, is a bulbous geophyte in the Amaryllidaceae family. Native to Europe, it thrives in temperate climates and is known for its attractive, nodding umbels of purple flowers. The plant undergoes a dormancy period during the winter months.
Allium carinatum prefers full sun and moderate temperatures. It should be watered regularly but allowed to dry out partially between waterings. The plant thrives in moderate humidity and should be protected from extreme cold.
Soil
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Good drainage is essential to prevent bulb rot, so a soil mix that includes sand or grit can be beneficial.
Fertilizer
A balanced fertilizer with a nutrient composition of 5-10-10 should be applied during the growing season. Fertilize sparingly to avoid overfeeding, which can lead to weak growth.
Repotting
Repotting should be done every few years in the fall after the plant has finished its growing season. Carefully lift the bulbs, separate any offsets, and replant them in fresh soil.
Propagation
Allium carinatum can be propagated by dividing the bulbs or by seed. Bulb division is best done in the fall, while seeds can be sown in the spring. Ensure the soil is well-draining and keep it moderately moist until the new plants establish.
Pruning
Pruning is generally not required for this plant. However, removing spent flower heads can help maintain its appearance and prevent self-seeding.
Toxicity
Allium carinatum is not toxic to pets or humans. However, as with all Allium species, it should be consumed in moderation if used in culinary applications.
