We originally received this as seed from a serious collector and grower in Scotland. While we much prefer to grow plants from documented wild provenance, this is sometimes nearly impossible to do and this is such a case. Nomocharis, like so many other genera, is enjoying some taxonomic dynamics with new species being introduced from the wild as well as species being added from the genus Lilium. The genus steadfastly remains one of the most coveted in the Liliaceae in our opinion and the thrill of seeing these in flower each year is felt as keenly as if it was the first time. We've had good reports from customers with Nomocharis in zone 5.
