Stickseed (Hackelia virginiana) does not have showy flowers. Each flower is about 1/8" across, consisting of 5 petals and a hairy green calyx with 5 long teeth. The petals are white and well-rounded; less often, they are light blue. The blooming period occurs during the summer and lasts about 2-3 months; only a few flowers are in bloom at the same time and they are fairly inconspicuous.
