I think I would leave the cleome seeds for a while yet before giving up hope. I've not grown them before but most advice is the majority of seeds can take between 7- 21 days to geminate.
I sowed some Lupin seeds last year as well Dave, I've got a couple of plants that are sprouting some green leaves so hopefully they will grow into plants this year, not sure about them flowering them this year though.
Hi Sam, started off some more wallflowers last weekend as well as some sweet rocket, all have geminated well, I did put some of the rudebekias out in the cold frame a couple of days ago but they didn't do well with the cold temps so I've had to move them back indoors. They have bounced back so will wait for a bit before trying them outdoors again.
