Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.

  • Description

  • Notes

German garlic is a perennial bulb that produces long, strap-like leaves of bluish-grey, that have a pleasing bright onion scent when crushed. Flowers are pink globes that appear in July and August. All parts of this plant have an oniony smell when cut or bruised. Although the leaves are edible, this plant is considered to be an ornamental and is not usually used for culinary purposes. Grows 18 inches tall (foliage is usually under 8 inches) and wide. A. s. var glaucum has interesting twisting leaves and is slightly shorter than the species.
Grow in full sun to part shade in well drained, dry to medium dry soil. Will slowly naturalize as clumps spread and through reseeding. If you wish to control re-seeding, deadhead the flowers before seeds form. This plant is attractive to bees, butterflies, and birds; deer tend to leave it alone. Drought-tolerant and well suited to a low water garden. A. sativum is the culinary garlic and A. schoenoprasum is chive.
