Pteridophytes at The Rockland Botanical Garden, Berks County, Pennsylvania

The large list of indigenous pteridophytes was made during the first few years of surveying the woods. To that collection has been added native North American ferns. There is a small section of the woods devoted to Japanese wildflowers and ferns. The ferns have been purchased mainly from Fancy Fronds, Foliage Gardens., Siskiyou Gardens, and Wildwood. While the hardiness map places the Garden in Zone 6, most of the purchased ferns listed as Zone 6 do not winter over or send up fronds in June and July. If the hardinesses of the ferns are correct, we have a microclimate of Zone 5.

All the plants listed below are currently growing at the Garden. Those marked ”*” have been planted during the Spring of 1997.
