Thank you for bringing up Flame acanthus, I'm adding it to my 'want list'.
It's been kinda slim pickings for wildflowers here too, so far. Although tall boneset and goldenrod are blooming okay. I'm leaving blooms in my garden just for the bees and butterflies, even though I dread all of the seeds that will follow. On the opposite side of that, something keeps eating all of the flowers and seeds from my salvia, Coral Nymph, seeds I would like to save!!
Turk's Cap is a favorite butterfly plant here right now.
