Pale spike lobelia's name is accurate. The flower spikes are unbranched, lined with pale blue to white flowers. Those flowers are about a quarter inch long. Individually, the plants are not real showy. Given an opportunity they will form a very attractive colony. This one grows in a sandy borrow pit next to a golf course. An opportunity for it, and for us (no, not the golf!).
