Sylvia has a compact plant that can grow in small spaces in your garden – 18 to 24 inches in height. And surprisingly, those compact plants produce up to 50 sprouts per stalk. Roasted, grilled or sauteed, you can’t beat the flavor of this powerhouse. A cup of them will give you nearly all of the vitamin C & K that you need in a day. Harvest after the first fall frost for best flavor. 140 to 145 days.
