Dear Marilyn, Welcome to the PBS list! I too live in PA (north of Phila.) and in the past, I grew quite a few Lachenalias indoors under lights. I found that they grew and bloomed most successfully with very bright light and very cool temps. In the attic room where I grew them, the winter temps stayed in the low 40's F for days on end and sometimes went into the high 30's. And that's what they liked the best. Not long ago Mary Sue reposted an introduction to lachs from Don Journet in Australia. You can find it in the archives or perhaps on the wiki, and Don's email address may even be there (I don't remember if he is a member of our list.) He is a very nice guy and grows zillions of lachenalias. Dell Sherk, Director, PBS BX SE PA, Zone 6/7
