How can you assume that Kolomitka does best in shade without some kind of
controlled experiment? My cultivars were all the ones carried by Raintree
and they all grew with great vigor and bore well when not frozen out in full
sun in southeastern NY. No scald or any issues whatsoever for the 8 years I
hosted them. Maybe harsh wind or some other factor I don't experience here
is the issue.
