Wakeshine, they are fine. You won't know the exact colours until they flower, being seed raised, but, yes, as aym said, keep them
they will not need too much warmth so outside for sure in pots...not into the ground. Keep them free from slugs.....watch out for the small guys under your pots. Every day lift up your pots to check for them. They will be there
i think they have every chance of flowering next year but I would pot on again rather than plant out until spring.
delphiniums are certainly worth it. I have several clumps that flowered profusely and many of them are now about to flower again...I will post pictures in a few days. I fully expect them to flower again in late September...if anyone disagrees I will post more pics ....so delphiniums can be full value plants.
The critical time for delphiniums is when new shoots appear in spring so in pots they will have a far better chance. A few.....half a dozen ...pellets evenly distributed around the crowns, not too close, is effective. An overdose of them will simply attract the blighters.
confidence, optimism and sensible precautions will enable you to grow beautiful delphiniums. Early staking too, of course
