Gardeners' Notes:

My Sabal blackburnia was planted in spring 2006 just north of San Antonio. It has seen ice storms, 16 degrees F, and 60 hours of below freezing weather, 60 100 plus degree days and drought with no damage.

This 'species' is not really a described species, but has been in cultivation long enough it is starting to gain some acceptance as something unique. It is probably a cross of Sabal bermuda with something else, possibly Sabal domingensis. Either way, it has some exceptionally recurved costapalmate blue-green leaves and is a relatively fast grower (at least in my garden). Unfortunately I don't have a really classic photo of either to show at this time- one with potassium deficiency, and one in the tropics (not a typical look there)
