Hoping for a bit of advice on planting up a yet to be built drystone wall, which is to replace our over grown border of shrubs, which is taking up too much space in our small garden. Wall will be just under 6' high & around a run of 18', & planted face will generally be in quite shaded conditions - will get morning & evening sun (when it shines, that is in rural North Yorkshire !)
I would like to encorporate some planting within the stones, & it has been suggested to include 'pockets' of soil, at random points within the wall as it goes up, perhaps including some seeds in the soil.
I would like to create sort of a natural looking rock garden effect, I really like ferns, brackens, foxgloves & would also like splashes of colour, scent, with some evergreens & mosses. We can also grow from the base upwards, but I don't want to loose much 'depth' into the garden, as before. Basically we would like to position some form of seating near to the wall, as this is where we get our aforementioned evening sun !
Any suggestions on what medium to use for the soil 'pockets' & plants to create that 'Edwardian-rock-garden' wow factor would be gratefully received ! Many thanks
