Small plants for the edges of raised pallet beds
I was wondering if anyone has any advice for some small plants which I could use around the external base of my raised pallet frame vegetable gardens? Something decorative would be nice. But they would need to be small enough to not get in the way of gardening in the raised beds themselves.
I currently have a layer of bark on the ground, and the soil under the bark is a little clay like.
We live in Bergen in Norway, so it would need to be something that could overwinter some cold temperatures (down to -10c in winter).
Thank you for any advice!
