Long Island Brussels Sprouts. Heirloom variety. These semi-dwarf plants are stocky with leaves closely spaced, so there are lots of tasty sprouts on the short, self-supporting stems. Introduced at the end of the 19th century, this was once one of the most important commercial varieties. It’s still a great pick today. I start these seeds indoors in mid-July and transplant into the garden over Labor Day. They are sweet and delicious when picked after a frost. Packet contains 15 seeds.
