Multilobed Soft Shield Fern (Polystichum setiferum 'Multilobum type')

10.00

The original cultivar name 'Multilobum' was applied to a wild collection made in Devon, England in 1865.  This plant had nearly erect fronds that were narrowly triangular or lance shaped with the pinnae divided 3 times (tripinnate).  The Multilobum group as it is classified today is much like the species, but sometimes can be even further divided like ferns in the Divisilobum group, which tend to be divided 4 or more times.  To further confuse identification, some ferns in the Multilobum group may also display characteristics of being 'plumose,' meaning that their pinnae tend to slightly overlap and turn down at the edges, making for a lacy, plume-like appearance.  Because of these subtle distinctions there is a murky line between the Multilobum group and the Divisilobum group as they are sold today, as both spore and tissue culture progency vary considerably in habit and degree of division.  Specific named forms must be propagated vegetatively to achieve consistent results, but on the whole tissue culture and spore grown progeny also make excellent garden subjects.  Regardless, Multilobums make a wonderfully lacy, evergreen addition to any garden and also do very well in containers.
