I live in Northern California and planted a Chinese Pistache in my backyard in May '08. I was very disappointed w/ the (lack of) Fall color last year but chalked it up to the tree being newly planted and young - it never turned anything but various shades of brown before the leaves fell off. At the time I purchased the tree I was unaware of the Keith Davey variety and have since confirmed that the tree we have is NOT that variety (unfortunately); I have also confirmed that our tree is male. My concern is that I have seen other very young trees w/ rather impressive fall color and I can't help but wonder if we have a 'dud' in terms of color performance. I'm going to give it one more Fall season but if it does not produce significant color this year I am tempted to pull it out while it's still young and purchase a Keith Davey variety since the whole point of planting this particular tree was to enjoy the brilliant fall color. I would appreciate any input/advice on this matter.
