Tropaeolum notes

Incidentally, Tropaeolum tricolor in my bulb frame has worked its way out
of the covering lights and has extended its stem onto the superstructure of
the frame, despite occasional frost and far too much rain. So far the
exposed part shows no damage.
Jane,
T. tricolor isn't bothered by -8 or -9'C in the slightest. I grow it
outside here, both in 8 inch black plastic pots and in the
ground. No problemo at all here at least, but obviously I can't
vouch for any colder. At those temps there isn't any damage to
either leaves or flowers regardless of the frost or how early the sun
gets to it (my pots are in an area where they get the morning sun, so
if the temps were bothering it they would get maximum damage. Winter
rains don't seem to bother it at all either.
Cheers.
