Sand Dropseed. Sand Dropseed is a warm season, perennial bunch grass that grows to a height of 1 to 2 1/2 feet. Growth starts in mid-spring and plants are mature by mid summer. It is a prolific seed producer and has high drought tolerance, allowing it to take over thin stands of alfalfa or other less greedy grasses.
