Alligator fern,microsorum musifolium-not hardy
Mine was tried outdoors in the S.F Bay Area,And it died despite not haveing frost touch it. Maybe no surprise, but since it showed up for sale world over last summer I thought some might be wondering how much cold this exotic looking fern will take. Basically,the length of our winter is too much despite a winter low of "only" 36F.
And IF it is alive somewhere down deep in the rootball,that does not change my opinion that it is strictly indoor or greenhouse.It would never grow enough this summer to make up for the winter.
