I,d go ahead and sow them, they may be a little late but then the flowers will be later.
With this spring its probably been best to have waited anyway

I agree Pam. I have just today put in some half hardies and, with the sea, we are no colder than Cambs.

thanks pamg ,yes its been a rotton spring, but the weather is looking a bit better now

thanks sarraceniac ,we have put our half hardys out,and they are growing fine, just hope there is no frost

Just gale force wind thunder lighning and torrential rain......oh and sunshine as well!

I was looking at my annuals cosmos, calendula, zinnia and calafornian poppiesall germinated in the last week or so, I think yours will be fine
