Do you know the garlic you purchased from the stores are probably imported? Garlic is grown globally, but China is by far the largest producer. Our garlic seedlings are organically and locally grown in N. California from seeds. Garlic is easy to grow and can be grown year-round in mild climates. In cold climates, cloves can be planted in the ground about six weeks before the soil freezes and harvested in late spring. Garlic plants are not attacked by pests. Garlic are easily grown in containers of sufficient depth.
You might not know, in addition to the edible bulbs, garlic green or garlic scape are edible and considered delicacy. Green garlic is simply immature garlic and looks like a slightly overgrown scallion or green onion. Garlic scapes are the curled flower stalks of hardnecked garlic varieties grown in colder climates. They are cut off by growers to encourage better bulb growth and available through early spring. Demand for both green garlic and garlic scapes is growing as more restaurants put them on their menus and people discover their mild but distinct flavor. They are mainly available at farmers markets or gourmet markets. So why not grown your own 'perennial delicacy'?
