This is a perennial bunching onion, which will keep dividing and reproducing itself indefinitely. The tops are available throughout the winter.
Foliage dies back in summer and small (pickling-size) bulbs can be dug, or you can leave the patch to sprout again in late summer.
BOTANICAL NAME: Allium fistulosum
Start in flats in Spring. Onions do best in rich, moist, loose soil, but this one will accept any good garden soil. Transplant 10" apart after frost. Keep watered-dry soil may spilt bulbs. Keep young sprouts well-weeded. Since this is perennial prepare bed very well. Harvest tops as needed like chives, or small onions in summer. Spread compost on the bed yearly, and weed well before sprouts emerge in spring.
