Plants reach 30 to 36 inches tall.

Quick-to-finish, non-heading plants produce plenty of succulent greens! 80 days. A beloved favorite for many years, Georgia is tops for tender, moist bite and reliably heavy yields. The non-heading plants reach 30 to 36 inches tall, producing abundantly, and the greens are unsurpassed for fresh-collard taste. Collards are wonderfully tolerant of both heat and cold; in fact, their flavor is sweetened by a little frost. Sow seeds directly in early spring or in late summer for a fall crop; or start indoors 5 to 7 weeks before setting out. If you want tall plants with full-sized leaves to harvest all at once space the seedlings 15 inches apart. For smaller plants with leaves that can be picked as they arise, space them just 6 to 8 inches apart

I own a small town home & garden store and I buy my loose garden seeds in bulk and measure them by scoops based on volume not weight. I use the Keystone Seed Scoop "A" for 1/2 ounce and "B" for 1 ounce.
