It's been a while since I posted anything, and a couple people have asked.
Sorry about that. Here's the situation:
I recently moved 300 miles away, so I honestly don't know what's up with the patch of flowers at this point.
The last time I was back home, I looked, and the spot was full of plants coming up. I can't say whether they were the flowers, or just weeds, because there weren't actually any flowers yet, but whatever the plants were, they were growing fine.
I would have taken a picture anyway, but I didn't have my camera.
Next time I'm back in town, I'll check it out and try to get some pictures. At present, I don't have any plans to be back there before July, but either way I will make an effort to keep an update.
