Han, my suggestion is that you should consider using the "hardy form" of leucoxylon from the new zealand suppliers----a plant that is likely from their seed is doing well here near the oregon coast and survived temps that defoliated e. saligna(about -7c or so) however, am not sure if the original seed is from a colored flower form or not (moreover, because of genetic variation there is no guarantee that a pink flowered parent will have pink flowered progeny and all bets are completely off if you cross a colored flower form with a completely different species with white flowers). sideroxlyon is generally regarded in the u.s. as somewhat less cold hardy than leucoxylon and caesia is a western australian species that may be less tolerant of a combination of cool to cold temps and wettish soils in winter typical of temperate rather than mediterranean type climates. i would also add that cold tolerance in hybrids may or may not be intermeddiate as a hybrid may in certain characteristics lean toward one parent and in others toward the other parent---thats in the first generation, progeny from the second generation may be even more variable. hopefully, the "children" of any cross will come out looking as nice as the one pictured in Denmark. hope this helps. good luck.
