I have this tree growing in my front flower bed. It started growing maybe about a year ago and has grown pretty rapidly. The leaves fall off in the winter. I haven't found anything identical in the neighborhood although it looks similar to Chinese Pistache in the leaf structure.

I'd like to know what tree this is and whether I should let it grow or cut it off. It does add a different look to the flower bed, although it is keeping some other smaller shrubs in the shade. This is in McKinney, TX, in Collin County, just north of 121.

Thanks!
