From what I understand, sundews don't take the energy-hit that flytraps do when they bloom. They're very small flowers, but pretty.
And...they can make lots of seeds if you're wanting to grow more plants...even if you simply let them go to seed, fall onto the surface of the grow-mix and "volunteer" for later thinning. Or you can let them go to seed, let the seeds ripen, and catch the seeds for planting in other pots, giving away, sticking in the refrigerator for later planting, etc.,. Or, you can whack the flowers off and not worry about'em anymore. But, if you whack them off you have to get a crazed look in your eyes and give a villainous, evil laugh when you do the deed!!!
