A similar question cropped up last year on UK Oasis when a Paignton
member reported having a pale lemon-flowered Acacia that did its stuff
much later than dealbata. Having seen the Paignton tree, I'm of the
opinion that it is probably a late flowering form of A. dealbata 'sub-
alpina'. Last year the tree flowered earlier (April/May), but I'm not
sure what it did this year. I must ask the question.
