Hi there
Thanks for all the ideas. I actually have some Californian Poppy seeds I
meant to sow last year, so I'll certainly try those. I meant Rosebay Willow
Herb rather than the Clematis that was mentioned. And I have a fondness for
Nasturtiums for obscure reasons, so I'll give those a try (I probably should
have mentioned that this little strip is adjacent to a chain link fence.

Thanks a lot.
