I rather like this plant-based theme. I also like that both Across and Down clues are used for theme material, which always makes it seem a little more complete. Or elegant. Or both. Mr. Polin also managed to squeeze extra plant material into two corners with FERN (14A: Bit of office greenery) and YEWS (56D: Trees for making longbows).
Oh, I wasn't going to single out any more answers, but I loved OPIUMDEN (37D: Old-time drug hangout), JOWLS (27D: Features of a droopy face), and Frannie always enjoyed watching "Pimp My Ride" when we could catch it while at a hotel, so XZIBIT (48D: Rapper who hosted MTV's "Pimp My Ride") was fun to have in there, too.
In possibly non-Tuesday material, we have VIRAGO (25A: Shrew), LARUE (52D: Lash ____ of old westerns), and MESTIZA (49A: Mujer of mixed race). Those last two I have never seen before!
Overall, this was a very good Tuesday.
