> the best type of pepper to grow when one is restricted to using plant > pots and window boxes ? C. chinense, e.g. habanero, scotch bonnet, aji yuquitania, fatalli, etc., are usually compact plants that abundantly produce fruits which are both pungent and flavorful, hence are awfully good candidates for your situation. They have certainly done well for me in pots (almost always better, in my conditions, than same plants in the ground, in fact). Just to keep things in perspective, most C. annuum and C. baccatum varieties have done better for me in ground than in pots (though all species and varieties of chiles I have grown in pots have produced acceptably there). --- Brent
