Imperial Whitetail Clover, with Whitetail Institute annual forage brassicas for increased early production and late-season tonnage. DOUBLE-CROSS is designed to produce a variety of forage choices for your deer, and do it in a hurry. The clovers in DOUBLE-CROSS are cold-tolerant and can remain green and attractive even under the snow. The brassicas in DOUBLE-CROSS become even sweeter after the first frosts of fall and stand tall in the snow, providing additional, highly nutritious food for deer in the late fall and winter. After winter, the clovers are still available, providing critical high protein during the 200-day antler-growing season of spring and summer. Double-Cross is a perennial and is designed to last up to 5 years without replanting. If you have been looking for a perennial blend with the proven performance of Imperial Whitetail Clover, plus the increased early-and late-season tonnage of brassicas, DOUBLE-CROSS is your answer. Double-Cross is designed to be planted in late summer or fall.
