Aha! That Pardancanda is a hybrid from the Belamcanda chinensis. Copied this off the site Lin posted:
"This Park introduction is a cross between Pardanthopsis and Belamcanda.
Belamcanda chinensis is a wildflower from china that looks almost identical but the new cross has a much larger color range.
Foliage looks like the leaves of Iris but is less sturdy "
So, is the original posting a wildflower, or would it more likely be the hybrid?
