Orange-croziered Wallich's Wood Fern (Dryopteris wallichiana subsp. nepalensis 'Molten Lava')

10.00

This subspecies of Wallich's wood fern caused no end of confusion when I first grew it from spores collected in Martin Rickard's garden in 1991. It was labeled as D. lepidopoda in his collection at that time. I sent the samples of this sowing off to Dr. Barbara Hoshizaki as D. lepidopda and the identification she came back with was that it was D. wallichiana. We corresponded back and forth as I looked closely at the plant I had brought back from England labeled as D. lepidopda and she looked at the plants from the spores I had brought back. It wasn't until I sent her a second set of sporlings sown from spores grown from the D. lepidopoda I brought home as a plant that we finally sorted out the confusion. The reason that this subspecies could be confused with lepidopoda is that it has a slightly orange cast to the newly emerging croziers and the fronds' surface is more lustrous with the pinnae spaced further apart than on the typical form of wallichiana that has been in cultivation for so long. To distinquish it from the other wallichiana in the trade I nick-named this form 'Molten lava' due to the muddy orange new foliage reminiscent of cooling lava flows.
