Good to know, and beautiful plant. Thanks.
Perhaps this should be in a separate thread, but... Every year flea beetles attack my arugula plants just as they're starting to bolt. If I pull them out the beetles attack everything else in my "salad bar." If I leave them alone, the beetles totally demolish only the arugula then...poof! Disappear. The only downside is that they destroy most of the seed heads, too, but seed is cheap.
