Amaryllidoideae

 The latin name above, for one of a family of lilies common in the South.  We call them by a variety of names, Spider lily, Johnny-Jump-Up, Pop-Up Lily, they are a harbinger of autumn.  Generally a red color, we have two varieties in the yard, a white along a privacy fence, and a red near an oak tree.

It's considered bad luck to mow then down.  They'll be in bloom only for another week and the I'll weed-eat around that tree the next time I mow.
