if the graden is ready to take them plant them now, the soil is nicely warm and they will establish.

having said that I usually pot on 9cm pots into 0.5litre pots to get them to a bigger size. But then they would need some winter protection ready for planting out in Spring.

Thanks, Seaburngirl.

They are perfectly hardy when mature Penny, but if they are small with very little root, it will be safer to keep them under cover until Spring.

Thanks Sheila, i have never gtown them before this year when I bought a couple of small plants. I just love the blue spires of colour, but only one did really well. I'd love to grow more, especially as the bees adore them! I thinkI will keep the new ones under cover as you and Eileen suggest.
