Brussel Sprouts Long Island Improved Care Guide

Introduction

Brussel Sprouts Long Island Improved (Brassica oleracea var. gemmifera) is a classic, reliable variety that produces firm, flavorful sprouts along tall stalks. It is a moderate cool-season crop that requires a long growing period and performs best in Florida's fall season.
