You don't say where you live--midday sun in Texas is quite a different
thing than full sun in Maine. At any rate, my columbines and lady's mantle
do well with that amount of sun as long as they get a reasonable amount of
water.

My question is.....do I need to move the columbine and lady's mantle, or
can
they tolerate sun? they begin getting sun at about 11-12, and then they
are
in pretty full sun until about 2 or 3.
