Possibly Ornithogalum umbellatum - Star of Bethlehem. If so, it is very aggressive.

White flowers are chives. Round leaf plant a mallow species. Maybe Cheeses? Malva neglecta?

White flowers with small sword like leaves look like some sort of alliums. Don't think they are Star of Bethlehem. But can't really tell from photo. I have a plant app that is free and it identifies plants. Very good only one plant it has not been able to identify for me

Are the flowers coming from the plant with the geranium-shaped leaves? Or is the foliage the more grassy looking stuff? There are at least two types of plants in the photo and we need to know to which the flower belongs :-))

As said the round leaves are a Malva of some sort.

candiburns is there a scent to the foliage on the white flowering plant..

Garlic chives (Allium tuberosum)....they are flowering currently and re-seed themselves fairly easily.

I meant garlic chives, should have specified. Yes, they are blooming right now. I thought I had gotten rid of them all, but these white Allium flowers are appearing in a few spots. They are very pretty. I think they look better in thin, rather than thick clumps. One more dish for the bee buffet. I'm keeping a few around as fillers. Some garlic chives with your cheeses?

The white flowers are indeed growing from the plant I need identified, not the grassy stuff next to it. I will post another pic in a bit - of one in my back yard that isn't mixed in with anything else. The flowers are so cute, and the leaves are pretty also. I've never had them in my yard until this year, and I've lived here for 41 yrs. off and on. I have about 6 patches of them throughout my back yard, none in the front yard. I will look up the ID's you guys have given me, and greatly thank you all for the responses!! Another pic to follow soon.... :-) I hope you all have a great Sunday!

I think you need to get down amongst the plants and look more closely. The white flowers simply cannot be growing from the scalloped leaves. It is just not botanically possible. The white flowers are a species of Allium, will have grass like leaves and will smell of onions when rubbed or crushed. The scalloped leaves are a species of Malva and currently have seed heads on them. Previously they will have had pink flowers.

Yes, blooms being asked about belong to the Allium with the slender leaves. Flower heads with stalks connecting them to the grassy clumps can be seen right in the picture provided. The next step would be to verify that it is in fact the aforementioned A. tuberosum. And not another of the many species in the genus.

First off - you guys are right - the white flowers were NOT coming from this plant. My mistake. I have some purple Alliums growing in the front (or should I say, they've already done their thing for the season), but I've never had any white ones. These are in the alley though. If I can remember to collect some seeds from them, I'll plant some by the purple ones.

Secondly, here are some pics of the largest one of these growing in my back yard. You ca see some flowers getting close to blooming in the middle. Floral_uk said this looked to be Malva (Mallow), which is what I think too after looking around at quite a few online.

Thank you ALL for your help! Not only did the Mallow get identified, so did the Allium. I very much appreciate the help and comments!! :-)
