I have some african daisies that look like that. The folliage looks similar to african daisy from what I can tell.

Nice pictures, Ellen! I love the Puschkinia. I have just a couple that escaped the squirrels digging them out a few years ago right after planting. Now that I have had luck protecting newly planted bulbs with mesh pinned to the ground, I plan to buy more this fall. What is the one on the last picture? The blue one with the ferny foliage?

Also, it's on an open area, full sun. There were no big trees beside it. It's a forest preserve. So I don't think someone is watering it, just nature. Ok, I will search for Elderberry. I was thinking of purchasing one but I'm worried that it might be invasive! Like what I said above, I saw them in large groups this morning. Are they invasive? Also, the fragrance is totally different from lilac. I saw a description earlier on the web and it mentions that the fragrance is similar to lilac. I quite disagree with the article I saw. I can say that it was somewhat similar to the fragrance of Dama de Noche but much more sweeter like a candy.

drippy, that's what I noticed. The flower is so quick. It's beautiful but goes away so quick. Is it a weed? I'm just wondering why there is a pattern in the way it's coming up from the ground. It's in zigzag manner. Most of the ones I direct sowed are in zigzag manner. Thanks for the info! :)
