This plant goes from erupting to gestating seedpods in two weeks.
They pop up with flower buds, as do many spring ephemera, and rapidly unfurl. The rabbits don’t bother them; I have to wonder whether it is the anthocyanins that tint them red.
Within just a few days the leaves turn green and resemble butterfly wings. The buds turn white rapidly and open by midmorning one day.
The flowers were open before lunch.
By the following evening, most of the flowers were gone. A few lingered a couple of days.
The plants spend the following month growing larger leaves and ridiculous seedpods.
This year drought set in early, shortly after the plants eject their seeds, so the patch looks a little bedraggled. There are more photographs of twinleaf from previous years in this blog, in eluding a post about twinleaf at its silliest.
