Gardeners' Notes:


On Jan 12, 2006, twistedparrot from Galveston Island, TX (Zone 9b) wrote:

White Shell, and most of the other shell types (with the exception of Texas Lantern), do NOT retain the characteristic shell shape in extreme heat. In Southeast Texas, where summer temps routinely top 100 degrees and humidity hovers in the 80-percent range, the blooms "flatten out" quickly after opening. They're still delightful flowers with wonderful fragrances, but bear in mind their form may disappoint if that's the primary reason you want one.
