Dear Jim McK and all, Having killed a nice small Worsleya to cold, I can add my 2 cents. First every geographical climate variant may not give equal results. I grew a seedling Worsleya for a couple of years and it was kept outdoors in full sun exposed to sun and rain 24/7. It was planted in medium size to large gravel with a small percent of hummus soil. Given low concentration fertilizer it grew slowly but in a healthy manner. Each year I kept it outside even when temps approached mid 30s to 40s including light sleet price. At the first freeze it was wintered in a frost free green house. Of course the weather forecast did not call for even a hint of frost, but it was exposed to a brief period below 32 F for a few hours one night and it was DEAD - totally. I tried to revive and resuscitate, but nothing. Considering how well (or so I thought) it was growing, I’d sure love to get another seedling, but I have yet to give another a try. Some day, wishfully spoken. So my experience is that Worsleya cannot take any subfreezing temps, but is fine above that temp. Larger plants may be better able to withstand a light surface frosting. Good luck. Jim W. > On Dec 7, 2014, at 1:52 PM, Jim McKenney <jamesamckenney@verizon.net> wrote: > > Over the years we've had several discussions which touch on the cold tolerance of Worsleya. From those discussions and from reading elsewhere, I came to the conclusion that it would be safe to leave my Worsleya out during light overnight freezes. > > Jim McKenneyMontgomery County, Maryland, USA, USDA zone 7 > > James Waddick 8871 NW Brostrom Rd Kansas City, MO 64152-2711 USA Phone 816-746-1949 _______________________________________________ pbs mailing list pbs@lists.ibiblio.org http://pacificbulbsociety.org/list.php http://pacificbulbsociety.org/pbswiki/
