Discussion Open flowers are clustered at the top of the coil, resembling pieces of popcorn. Rusty Popcorn-flower is similar to species of Cryptantha, but Rusty Popcorn-flower is generally more softly hairy and grows in moister places. Many species have a purple dye in the stem, leaves, and roots. When they are pressed and dried in a folded sheet of clean paper, a striking mirror-image pattern results.
