and Lilium formosanum var. pricei Stoker. The latter is a high altitude ecotype which never the less >breeds true from seed and faithfully follows the temperate regional seasons.
I have one small clump of this. In both locations where it has been grown, Connecticut Zone 5 and here in North Carolina Zone 8ish, half bloom in June and half in late August or early September.
