Korean sun pears are just a varietal form of Pyrus calleryana, not a separate species. As such, they have or can have the same invasive tendencies as any other Callery pear. Not a great choice for most of the country :-(

If we are talking about the plant Pyrus fauriei 'Westwood' ('Korean Sun'TM), then one of my trade mags, Arbor Age, seems to like it.

But since we have no idea where the OP is located or anything about the location, there is no way we can give a decent opinion about the plant in context (keyboard macro #2).

Actually Dan, the correct taxonomy is Pyrus calleryana var. fauriei, so just another Callery pear, although slightly more compact and earlier to color than other cultivars.

I don't see it, GG, in ITIS and has the Pyrus faurei (Schnied.) been dropped somewhere that I can't find?

Anybody Google it?
