I have the following tropicals planted out in my raised beds. Coleus Ipomoea (decorative leaved forms) Senecio - "Angel Wings" Fuschias I have grown them all before except the Senecio. Treat them as bedding plants in that I let them get killed by the frost, and then replace them next spring. But am thinking of digging them up this year and overwintering in the greenhouse (min 5*C) Is this worth while? Or should I just do as in the past and replace them next year?
