Steve, I should note that it's possible what you got as H. crispus is not H. crispus and hence un-frilled. Assuming it is the right species, I think the light available in in your location are lacking. I grow in a backyard uncovered and my H. crispus are frilly enough - but not to match some of the finer specimens I have seen in photographs. My Berkeley neighborhood has few tall trees, so my bulbs get a lot of bright, open sky - good for sun but not so good on cold, clear nights. The amount of light a desert bulb receives is far more than suburban gardeners can offer. And there are very few grey days in the desert winter. Your cacti - which maintain their photosynthetic tissue year-round - get to enjoy the strong summer sun. Your Haemanthus must exert energy to grow its leaves anew each year - and at a time when the sun is weaker and overcast days are more common. And of course, even bulbs in habitat aren't always perfectly http://… ated -|<ipp > Date: Fri, 22 Jan 2016 00:03:44 -0500 > From: putman@pobox.upenn.edu > To: pbs@lists.ibiblio.org > Subject: Re: [pbs] Haemanthus crispus > > 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. > > Steve Putman, in coastal Delaware near the Delaware Bay > ----- Original Message ----- > From: "Kipp McMichael" <kimcmich@hotmail.com> > To: "Pacific Bulb Society" <pbs@lists.ibiblio.org> > Sent: Thursday, January 21, 2016 9:38:27 PM > Subject: Re: [pbs] Haemanthus crispus > > Stephen, > I will assume, given your anticipation of snow, that you're growing under lights. 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/ > > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/ > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/
