And it's attached to the daylily photo as a comment thus starting a thread in the Plant Photos forum.
Once you have seen this, I can import your image to the generic Rain Lily entry and I will delete this thread.
This is an awesome photo, I have always wanted some rain lilies but this person joined in 2018 and has never uploaded anything or gave a comment or thumb nor received any. Thanks for giving me the names of these cultivars!!
Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. Mat.6:28-29
