Geoff, so beautiful. Does it have any scent? Those faint colors on the tips of the lateral sepals are really cool. I hate to bring this up, but it looks like you had one of those sweet little long tailed mealy bugs on that pedicel. Suspect there is some tempting juice oozing out of there somewhere. Personally,I am experimenting with imidacloprid dosing for those little fellas. Great results so far but variable depending on manufacturer/brand.
