Plants to go in wall crevices

bogman_bass

we have dry jointed field stone alls on our house built with old reclaimed fieldstone

I want to lean into the “old” look of the house but putting the odd plant in the crevices.
I’m think in harts tongue fern, maidens hair spleen wort, Jacob’s ladder, wallflower and rock cress. Any other ideas?

I don’t want them to dominate the wall, just to give a little flavor here and there.

Its very difficult to 'force' a stone wall to grow plants, but if you have somewhere with any of the wall plants growing nearby you may be able to transfer a chunk of soil with a small plant. Don't expect to 'plant it up' the same way you would plant a border. If you have a channel with soil along the top you might put in aubretia/rock cress, you are unlikely to get it to grow 'wild' in a wall.

Harts tongue fern is very willing to grow in crevices if there is some locally, I find it growing all over the place. spleen wort is a bit difficult to get going, though it is appropriate. Wallflower is like aubretia, its a great theory but garden centre plants are not going to be very happy to grow in a wall. Not sure what you mean by Jacobs Ladder, if you mean polemonium its not really a wall plant. Toadflax is another that comes to mind, stonecrop and pennywort.

I think your best bet is to just wait and see what establishes itself, though it helps if there are walls nearby with plants that would be suitable. You can put soil in crevices but it is more likely to grow grass, dandelions, ivy, and numerous other things that tend to pull the wall down if you weed them out too vigorously.

It might be a bit big for you but Valerian is a nice one if you can get it to grow.

Mexican Fleabane aka Erigeron. Very easy to grow from seed.

some great advice there

I forgot about toad flax and penny wort.

Yea, I was going to accept a high failure rate and hope some of it takes

If you want Valerian to grow in your wall grow some in a pot nearby and let it go to seed. Takes a couple of years but it will end up growing in the wall.

Campanula is another one to add to the list maybe

Yes was just about to post that, seeds into rough walls easily if planted nearby.
