I've just finished planting out the spuds. Russian Banana is another one with a very good survival rate. Some of the coloured ones were interesting. At first glance, Blue Belle had good survival, but all the tubers were deep purple, while they'd originally had a range of colours. Obviously, they're all from one or two plants which inherited the right gene. There's a lot of slug damage, so they're not so good in that respect. Shoots very tremendously as well, even within a single line. Some tubers have shoots 8-9 inches long, while others show no sign of growth at all. I'll probably do something similar next winter, but try to keep the pots drier.
