Garlic
Allium sativum
Garlic doesn't have flowers that produce seeds — every garlic clove planted today is genetically identical to the cloves Roman legionnaires planted 2,000 years ago. Hardneck varieties produce 'bulbils' but they take 2 years to size up.
How to care for garlic
Plant individual cloves 2 inches deep, pointy-end up, in October — they need cold to vernalize. Cut scapes (curly flower stalks) on hardneck types when they appear in June for a 30% bigger bulb. Harvest when 1/3 of leaves yellow.
Garden uses & design ideas
Best garden use
Give it a practical bed with easy reach, steady water, and companion flowers nearby to support pollinators and pest balance.
Pair it with
Tomato, Rose, Cabbage make easy companion choices because they share similar light, water, or visual texture needs.
Layout tip
Match it with full sun exposure, place it in a moderate-water bed where soil can stay evenly damp but not soggy, and check USDA zones 3-11 (overwintered) before planting. Use the garden planner to test spacing around its mature size: 18-24 in tall (foliage); bulbs 1-3 in across.
Gardener note — Double-check local invasive, edible, and toxicity guidance with your county extension office before planting around pets, children, or natural areas.
Companion plants
Garlic grows well alongside these — similar light, water, and texture needs.
