Redbor Kale (F1 Hybrid 55 Days)

This one has been difficult to find for the past couple of years. It was one of our favorites, so we had to bring it back. The color of the mature leaves are unlike any other kale we offer. Harvest often, regrowth is strong after each cutting. Grows well into late fall when cooler temperatures sweeten the flavor and intensify the leaf color to a rich plum. Capture the beauty of it in your garden or container. Ready for harvest in just 7 weeks.

30 seeds



Brassica oleracea

Germination: 3-10 days

Transplant a week or two before the last frost. Space 12-18" apart. Sow in midsummer for fall crops. 

Sowing Outdoors: Starting in spring when the soil temperature reaches at least 55ºF. Sow 2-3 seeds every 12-18”. Sow closer to harvest baby greens. Thin to the strongest seedling per space. Sow in midsummer for fall crops. Germination is slower at lower soil temperatures.

Delicious and Fun

I've been growing this variety for 4 years. It is the mildest sweetest kale I've tasted to date and it gets even sweeter after a light freeze. Instead of producing many leaves from a center like Swiss Chard, this variety sends up stem that produces rings of kale leaves. It continues to grow until killed by a hard freeze. I've seen it get to over 6 ft tall. I grow mine in a high tunnel in Alaska and can usually continue to harvest until spring when I pull up old plant and sow a new one.
