Dates for planting out delicate perennials.

Hi everyone,

I have recently purchased the following:
Rudbeckia fulgida in 9cm pots
Echinacea purpurea
Achillea credo
Foxglove

The weather in the north of England is pretty dire at the moment and I have the plants on my window sill in the kitchen where they will receive lots of natural light but no direct sunlight. I am keeping them damp. Is this the best way to nurture them until the weather picks up and they are ready to plant out?! I don't want to kill them off before they've had a chance to grow!

Phil.

 

I'd keep them all indoors for now if it was me, except the foxglove, which is perfectly able to withstand a British winter, even in the north.
