Fern Hardiness

In his book ‘A Guide to Hardy Ferns’ (BPS Special Publication No. 1 ), which appeared in 1984, Richard Rush made the point that there was still much to learn about the hardiness of many ferns. You can help us to improve our knowledge by completing this questionnaire for ferns that you grow outside in the UK or Eire.

Please fill out the questionnaires which you can find on the right

In order to help you catalog your ferns, there is a Check List of the currently known non-native ferns that you can print out on one sheet of paper and take around your garden to tick off what you have
