They look a bit familiar but for the life of me I can't figure out what plant they come from. We've been in this house almost 3 months and day before yesterday and yesterday I found a single flower laying in the lawn. This morning there were six flowers scattered in a small area of the lawn. I've walked our entire property and can't find anything like this in bloom so I'm assuming they were blown from a neighboring property or some critter carried them in, but probably the wind blew them from somewhere. I'm hoping someone recognizes this bloom from these awful photos. I was in a hurry to get somewhere when I took these but tomorrow if there are more flowers laying in the yard I will try to get better pictures. Blooms are about the size of a quarter or a tiny bit larger. When found, they were all closed as shown in the first photo; I opened the others for the pictures.

They look very Magnolia like, but I don't know of any magnolias with blooms that small.

Any citrus trees in the area? Kinda late for blooming citrus, but the blooms remind me vaguely of citrus flowers.

Any yuccas nearby?

...or that!

Lin, do they have any fragrance?

Yes ... and I should have looked up because the blooms are coming from the plants on the side of the house where I found them in the lawn.

Thanks Kent for the ID! I'm really for not noticing these trees blooming but they are really tall, rising way above the second story of the house. I was looking at shrubs all around the property for white flowers, never thought to look way up. It's been raining (thankfully) and the humidity kept fogging my camera lens but I got a couple of pic's.

nice tree Lin wish it grew here in zone 7b

@ediblelandscapingsc Daniel, the Adam's Needle (Yucca filamentosa) will grow in your area ... they are apparently hardy even to zone 4 according to the database! Only thing about that one is the dagger like pointed ends. Ouch! They are really dangerous! A couple apparently grow in S.C. https://commons.wikimedia.org/...
Spanish Dagger (Yucca gloriosa)
Spanish Bayonet (Yucca aloifolia)

The common name "Spanish Bayonet" fits perfectly .... oooh, those sharp points! Back in 1975 we dug out tons of low growing Y. filamentosa from our yard because of those dangerous pointed tips.

I have about 50 Adam's Needle yucca plants, hoping to acquire soap tree yucca and color guard yucca before long also.
