Obtained plant in tuber swap from Emily S, connected with Ann Arbor Dahlias FB page.
Actually, I have a plant that is similar to this. Will post a photo on my own plant list.
Events

April 29, 2022: Seeds sown (Tubers sown -- Laid tubers onto soil bed indoors in humidity dome) to "wake up" the dahlias.)
