Add to wishlist Remove from wishlist
This a bigger version of the little B. penna-marina ssp. alpina commonly found in nurseries. We never see this offered which is just a shame since it is a great fern. Well, not such a shame since a little exclusivity never hurts. This makes a dense groundcover of evergreen foliage.
