Nettles in Yangzi Cave China

Southwestern China, Myanmar and northern Vietnam contain one of the oldest exposed outcrops of limestone in the world. Within this area are thousands of caves and gorges. Wei Yi-Gang (Chinese Academy of Sciences, Guangxi Institute of Botany) and Alex Monro (Kew) have been exploring these caves and gorges for plants from the nettle family (Urticaceae).

Alex initially thought that reports of “cave-dwelling plants” were due to a mistranslation of a Chinese word. However, a visit to the first cave, Yangzi cave in Guangxi, did indeed reveal clumps of small plants growing deep within the entrance where light levels were as little as 0.04% full sunlight.

The cave explorations have so far yielded 10 species new to science, seven from the genus Elatostema and three from Pilea (two species-rich genera of succulent nettles that together total probably more than 1,500 species). The new species often occur in only one or two localities and are restricted to the deep shade of forests, stream sides, gorges and caves.

the cannabis plant, I've been reading, that it has different uses with the different species of the plant. Is it the same with different species of nettle? And can Nettle be grown in NC ? if so, where can I get Info. on how to grow it here.? Thank you.
