i have a large 'Red Flash' caladium indoors for 8 years. since it's a large variety (large leaves), it has larger tubers. none of my tubers died in 8 years. i dig them up and store at about 60F indoors in plastic bins with holes - it provides a bit of protection against dehydration and keeps them dry to prevent rot. i have also overwintered small lance varieties - but with variable success. the smaller the tubers, the harder to overwinter them. the small varieties i keep in pot in soil until mid-april, beginning of may. they are slow to start, unless you put them on a heat mat, in peat, and keep them moist and tented for humidity. then in about 5 weeks you'll get sprouts. otherwise it could take 2 mo to get them going.... i keep them on a heat mat until i have sev leaves on each tuber. then it's south or south-west window indoors and humidity has to be above 65%. mine is usually higher by may, around 75%. i have grown 'Miss Muffet', 'Florida Sweetheart' and 'White Queen' completely indoors - and they do fine. but ONLY if they get enough sun and you don't let them dry up. the soil temp is key, when soil temps drop below 65F, they go dormant. and keep in mind that soil temp is prolly 5F lower then air-temp. so ..if you can't supply steady 75F air-temps - forget it. AND they prefer 80-85F for good growth - that can be a problem in england, unless you put them outside? IF you put them outside, you still need to monitor night temp - HAS to be above 72F for good growth. If you have a southern or western window you temps will go 10F higher directly by the window. so at ambient 75F indoors in summer you'll get required temps for growth even indoors (without sweating too much :) ). in general they will grow for 6 mo and then decline. and need to be stored dry overwinter (in soil or not - see above). they do go dormant when planted outside even in south florida, even in warm winters, when it's 60-65F at nite and 75F during the day. but of course some winters it can be 50F for a few weeks - that's too cold for them...but i'm talking about very warm winters when it does not drop below 60F much at nite - and they still go dormant.

GP,Seems like you had fun.Beautiful plants and love the bears. Blueberry cobbler? YUM,my favorite!! Felix

My youngest are almost 11 now - a boy and a girl (twins). Hard to believe so much time has gone by. It's difficult to get teenagers interested in doing family things but the younger ones still like to get out and go places - as long as I give them enough time to save their game on the Playstation first. lol I didn't know about the daylily and hosta sale. I think there is a garden tour for the Garden Railroad Club this weekend. My son would like that. He doesn't care for the garden part of it but he does like trains.

The photobucket C&P shows as a link. Now, I'm trying the direct copy from my phone's camera roll.
