The two raspberries around here (R occidentalis and idaeus) have mostly 3 leaflets, not five as in the picture. And the thorns aren't as big. Of course that's in NJ, I suspect Tennesee has some species we don't have up here. WW

Here is a close up of the leaves and thorns. Any assistance is appreciated.

Are they actually toothed? I noticed that but thought it was more of a wavy edge which bays often do have. But now I've looked at the close up in the album so I won't insist. I didn't realise the OP was in 7b. How did you discover that?

mimosa can live through hard freezes with no damage. they also have pretty extensive root systems and won't usually blow over, even in a strong wind (I have two of them, they grow wild in the south, where i'm from). they bloom in the spring and throughout the summer and are very fragrant. they aren't evergreen, mine will be naked in a couple weeks. however, the bark in the above pic does look like mimosa. debbie
