They have been winter hardy for me in zone 7a, north of Memphis.
I tend to like perennial plants that I can leave in the soil over winter,
but I recently broke down
and bought some Caladium tubers that were on clearance for $1.00 per 6 pack.
I'm wondering if
anyone has any hands-on experience with them surviving over winter outside
in zone 7b, especially in
I know that the "expert" sites say that they must be dug up and replanted to
survive, but they say
the same thing about other plants that I have that DO reliably come back
year after year, like
canas, elephant ears, and gladiolus. The "experts" even say that the
"Christmas Cherry" Solanum
pseudocapsicum is killed by zone 7 temperatures when mine are evergreen even
in the dead of winter.
So I don't put TOO much weight on the "official" zone hardiness. Anyone
know for sure if they
REALLY can or can't overwinter in 7b?
