No. Nasturtiums are the best, followed by pansies. Not only do they taste great, but they make wonderful salad garnish. BTW, we're all eating flower petals when we eat artichokes. And eating flowers doesn't just have to be about the petals. With honeysuckle, you can actually suck the "honey" (nectar) out of the bottom of the blossom if you pluck it just right. However, you are correct to note that all plant eating, if done on site, rather than done by harvesting and washing, needs to be done with caution so as to avoid any nasty insect surprises. But on that note, there are a great many tasty insects out there. On the whole, we Americans are way too squeamish about what we eat. It makes for a very limited cuisine and is wasteful of potential food resources.
