Kipp, Geographic attribute of your assumption is correct. But..I am growing in a greenhouse with heater. So it gets full sun (though less than in a desert), and the temperature varies from 48 to 80 F. I do regularly flower a few cactus plants I've had since the early 1970's. Question is, how much light is "enough". Still waiting for the snow.

Attractive foliar forms - such as twists, ruffles and glaucous-ity, are usually associated with strong lighting. I don't think you're H. crispus is flat, it is more likely that it is simply not experiencing the light intensity (and perhaps temps or humidity) that would, in its natural habitat, elicit crisped leaves. -|<ipp > Date: Thu, 21 Jan 2016 20:50:44 -0500 > From: putman@pobox.upenn.edu > To: pbs@lists.ibiblio.org > Subject: [pbs] Haemanthus crispus > > Keeping amused while awaiting the arrival of the snow. > > I am growing a Hamantheus crispus. It has one nice leaf (current growth) about 7" long. But..this leaf, while attractively spotted, has no undulating edges. Is the undulation something that develops with the maturation of the bulb? Or, do I just have a "flat" one? > > Steve Putman > > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/
