I once got a packet of seeds for Swiss Chard (green, not the red stuff) and those seeds are VERY obvious for what they are. If you ever see one, you would never miss the ID. And in the packet were two little round seeds that DIDN'T look like they came from the planet Klingon. I assumed they were okra and dumped them at the gutter, because I didn't want them in my chard.
Buy certified seed.
Or better yet, save seed.

That was the idea. I was going to grow a mixture and decide what we liked and didn't like and then save the seeds of what we liked. Looks like Mother Nature is still having fun at my expense. I have some bibb, tipburn, etc. so that can go in. I just read that hemlock smells like skunk but the pics aren't even close to matching. I already knew but this is more proof that we must pay attention to nature. If something smells like skunk, it's wise to stay away from it.
