Nasturtiums?

I have a semi-shaded corner that has a large conifer at the back of it; with the reshaping of the lawn recently done, there is now a bit more border space in front of the tree, but it is never really going to come to anything meaningful. I don't want it bare (and I sort of want to have plants that deter the dog from sneaking round the back of the tree to annoy next door's dog), and I want something that will grow quickly in what is pretty poor soil - hence, I am thinking nasturtiums.

But, is it too late to sow them, and if not should I bring them on in a seed tray first or just direct sow a packet or three?

I also have a packet of mint seeds, so I am wondering if I should lob them in there also - I know mint can be a bit of a thug, which in this corner would not bother me?

 

Thank you both

I'll see what I can pick up this morning and get them down - I am not overly fussy about that corner as not much will survive there as its dry and shady

 

I got a couple of packets of nasturtiums when I was in Sainsburys earlier - they had nothing else that would have been suitable. I am hoping to get that side of the garden cleared tomorrow, so will sow them then; all I have to do thereafter is keep the dog off until they get themselves going
