Earlier this summer I went for a walk around my neighborhood and saw this beautiful Tacoma Stans. While it is hardly "mellow", it certainly is yellow! I have one is my yard that grows up over our roof and provides a lot of shade for the summer. I also have planted another small one on one of our porch boards, so that eventually it will grow up and through the porch slats and provide us with additional afternoon shade. These plants grow very quickly here in the desert and they aren't expensive to buy! Mellow Yellow for August 9, 2010.
