Oyster Plant, Salsify (Tragpogon porrifolius) closed for evening

My rural country road has a good population of the Oyster Plant in bloom. Somewhat of a minimalist in nature, they can be looked over like other see through varieties. When open, they display a bright yellow Dandelion-like flower, but by noon, close until next daylight (further promoting their reclusive nature). Perhaps most unique is the seedhead phase, during which time a massive seedhead  appears, subject to the vagaries of wind and rain. A bit of hairspray and careful transportation will preserve them for photographing during this final phase. Of interest, these plants are runaways from old domestic gardens in Mercer, Kentucky, where the Shakers cultivated them for the root, which allegedly tastes like oysters.
