85-110 days. Forget what you thought about Brussels sprouts as a child. Store-bought sprouts just can’t compare to those picked fresh from the garden. Each little sprout is firm and full of wonderful flavor. Try them roasted with other vegetables, a hearty meat or sausage. You can even leave them in the garden into the winter. Frost actually improves the flavor and the plants resemble little palm trees for a unique look when dusted with snow.
