Below are some volunteers that popped up in my pot of D. peltata this spring. The D. peltata are lying dormant below the soil level, but these guys continue to grow. I need to reduce watering, but don't want to kill off the volunteers. Any ideas on what they might be? Looks like a flower scape is forming and will be in bloom in a couple weeks' time. FYI- The plants are roughly 2-3" in diameter.
