Height and spread 30" x 24" inches, should flower this year, I'd pot them up till they get going, then plant out. You can plant them straight out, but it's easier to keep them watered in pots, which they will need.

Can I ask which mail order company as I bought some but dont know the variety of them. They wouldnt tell me either when i e-mailed them. :o(

Thanktyou to whoever responded to my question.
I bought the leucanthemum from Suttons 08449222899 or www.suttons.co.uk

I'll have a look at them thanks. :o)
