Hardy perennials........young plants
When or how do you decide when a young hardly perennial is hardy enough to go into the ground. I ask this due to the fact that wallflowers (annuals/biannual) planted now can go into the border for a Spring display, so does the same happen to hardy perennials planted now? I live in an area where we rarely get really cold weather and hardly any snow, therefore I don't lift my dahlia tubers, and they've survived the 3 winters I've lived here.
I also leave my gorgeous cannas in their pots outdoor all year round too, and they also survive and produce new tubers.

For me it's a question of size. Plants which are small can get lost or eaten or accidentally hoed so I always grow them on into at least a 4" or 10cm square pot before they go in the ground in groups of 3, 5 or 7 or a 6" pot for one that will be on its own.

There is no right or wrong time. It's all about the size, your type of soil and the kind of plant. If you watch Gardeners' World, Monty seems to be planting and moving things all through the year....So clearly he doesn't follow the advice.
A larger plant should be more slug resistant too. Annuals and biannuals only have a year or two to maturity so can be planted fairly small as they grow very quickly.
