I bought Paper Butterfly in the spring of 2022 and planted it in a prime spot. I ordered it because of its reputation for rust resistance. In less than a month, the plant sent up scapes, and it bloomed in June.
Unfortunately it showed rust several times after that, so when the plant did not return this spring (2023), I did not cry. I have only one picture of it in bloom, and you can see the characteristic canoeing.
