Owing to the great beauty and usefulness of the ferns in decorative lines,and the difficulties with which they are grown in the North and Northwest, numerous inquiries have come to us from time to time as to the best varieties. This led us to make some experiments in this direction.
A large number of ferns have been subjected to very rigid tests for several years, and the results have indeed been gratifying, as we have proven beyond doubt that many of the most beautiful ones will thrive and soon make handsome specimens with a little care.
