Deer Resistant Blooming Fern

(Cincinnati, OH, USA)

At a recent flower show in our area which is southwest Ohio I purchased some roots which were light tan and averaged about 4 inches long and about an inch in diameter. They were pictured as ferns with either pink or white flowers. They were advertised as very deer resistant and the vendor stated that they will bloom most of the summer. If you know what species of fern this is, please state it in an answer. Thanks.
