Dear All; Thanks for all the advice. I wish I could just grow it outdoors and give it plenty of TLC, but it is in a large pot and may need an even bigger one soon. Just want some flowers some day. I was surprised to read that there's something like 16 species found in both W. Africa and Central and South America. Most species are from Brazil. Sounds like the sort of genus you'd expect to find some specialist. Is there a national collection somewhere? N longifolia has smaller bright yellow flowers. The typical Walking Iris (as I mentioned not sure what is the correct species name*) is very common as a house plant. N. caerulea is a new one to me and I don't know of any other species in cultivation. Does anyone grow any other species in the genus. Maybe it does deserve a wiki page. Pix please.
