Burr Reed Family Aquatic Bays Mountain Park - Kingsport, TN June 23, 2007 Monoecious There were lots of these plants growing in the wetland areas along the bank of Bays Mountain Lake. The upper flowers are staminate or male, the green flowers are the pistillate or female flowers.
Pink Family Elizabethton, TN June 22, 2007 Unfortunately, I was not able to photograph these flowers until late in the afternoon, the petals had curled up already. I found these blooming in a crack in the pavement at a hotel parking lot! Sometimes I don't have to look very far to find flowers!
Arrowhead flowers are monoecious, the flower with the yellow stamens is male, the one with the green pistils if female. These flowers are insect pollinated.
