But that's my point Wills - they're not happy in the greenhouse - they don't need it and they don't like it. And January is not the best time to sow foxgloves - they're bi-ennial so they grow in one summer and then they flower the next.
Scatter foxglove seed around your garden in the summer, just as the wild ones do - within a few weeks they will grow where they have fallen - thin them out and let them continue to grow where they are.
They will form healthy plants, then in the winter they will die down and disappear. In the spring they'll reappear and grow and this time they'll grow the flower spikes and bloom.
After the flowers are over the seeds will drop and scatter naturally and it will all start again with virtually nothing for you to do. Even in Scotland they do this in the wild - they do not need the protection of a greenhouse. As you say they rot and die.
If you want to use your heated propagator can I suggest that you sow and grow types of plants that need heat to germinate rather than try to grow plants that hate it.
