Are you certain of your identification? Chamelaucium uncinatum is almost impossible to distinguish from Leptospermum scoparium, which is commonly available in the US.

@gardengal48 (PNW Z8/9) I was reading about South African plants, which is how I got onto Chaemelaucium. Chaemelaucium uncinaturm ends up at about 2 meters high, whereas the plant you are referring to (Manuka?) apparently becomes a larger tree.

" becomes a larger tree. "

Not very likely in this country. 6-10' is typically quoted although a smaller sized shrub (3-5') is much more likely.

mmm, have also spent many futile hours trying to track down the Geralton wax plant here in the UK...with no luck whatsoever. Seems to be one of those common plants in Australia which haven't gained any traction elsewhere (like parahebe perfoliata, another common Au plant, largely unheard of here (unlike parahebe catarractae, available in numerous incarnations).

@rosaprimula UK (Cambridge) Z8/9 I found it! There is an alternate spelling for the genus:
