Looks like erysimum 'Bowles mauve'. Perenial wallflower.
Just planted two this morning :)

Thank you sooo much!! I will soon be planting them too!!

it does to me too. I have just potted 3 on into larger pots. I'm glad I took cuttings as I lost my big plant this winter.

Your welcome Dedabum :)
Thanks for that SBG, I'll do that too this autumn-just in case ;p

I am so very pleased to have discovered the name of this plant . . it is indeed stunning! I can get 3 for £12.00 from the online shop of the rhs.

Mine were £4.99 each good sized plants from our local GC,if we manage to get plenty of cuttings that's even better.No doubt someone will come up with a better price lol !

Take cuttings mid summer from a non flowering shoot and get them rooted before the autumn. the are more likely to survive then.

Will do SBG thank you :)
