Thank you 'Moon Growe' for your reply.
I am in the north of England (South Yorkshire). The Delphiniums are young plants with tender new shoots about 2" high. I did consider planting them out in their permanent position but unsure as to whether they would survive the winter with them being so tender, hence them being potted so as to bring them under cover if needed.

Hello Moon growe,
My apologies for not responding to you in the correct box. I wasn't sure how to reply but I will know in future.
Many thanks for your advice and I will shelter them through the winter as you suggest.
Thank you again, much appreciated.

Jrp in future when you respond to your own question do so in the answers box below the question - makes it easier to follow what is happening. At the size the plants are and given where you live I would keep them in pots and be prepared to move them somewhere frost free for winter. They will die back completely by November so it isn't necessary to have them somewhere with a lot of light. You will need to ensure that they are hardened off before planting out next spring.
