Coniogramme jinggangshanensis 'Shishi'

Coniogramme jinggangshanensis 'Shishi' is a rather rare and unusual form of the Asian bamboo fern. The upright, dark glossy-green, 2' tall fronds are composed of large pinnae (fern leaflets), each ending in a fancy petticoat-like crest. Expect a 3' wide patch in 5 years, thanks to the spreading rhizome. Rich, moist soils result in the best growth, while very dry soils will slow its spread to a crawl...a dramatic and unique specimen in the garden! In mild winters, it remains completely evergreen, but when winter temperatures drop to single digits, it will be tardily deciduous. We originally acquired this as Coniogramme intermedia, but when we key it out, we found that to be incorrect.
