Whitehall will welcome noted fern expert Sue Olsen for a special talk on the merits of growing great ferns in your garden. Informal tours of Whitehall's woodland garden, an official display garden of the Hardy Fern Foundation, will take place immediately following the talk.

Sue Olsen has been studying, photographing and writing about ferns for more than four decades. Her nursery, Foliage Gardens, has introduced numerous ferns to horticulture. A founding member and first president of the Hardy Fern Foundation, Sue is editor of the Hardy Fern Foundation Quarterly. She is a graduate of Cornell University and lives in Bellevue, Washington. Ms. Olsen is the author of the Encyclopedia of Garden Ferns, the authoritative guide to the wealth of available garden-worthy ferns.
