Austroblechnum penna-marina subsp. alpina - Smallest Form


Add to wishlist Remove from wishlist
Nomenclature. Kew retains the genus Blechnum while others accept the newer Austroblechnum and at this point, we're not changing it back to Blechnum! This small form of the subspecies was shared with us by the Fern Madam, Judith Jones of Fancy Fronds Nursery. Excellent dense groundcover fern for moist spots. Can take full sun in cool sun areas if moist.
