heathers in a wall

Hi, I would really appreciate any advice on growing heathers. I am trying to create a nature trail around a large garden and I thought I could make a feature out of an old south facing dry stone wall. It already has little ferns, mosses and lichens growing in it but I hoped that perhaps I could introduce some native heather species to encourage bees, butterflies and other insects to visit. I was wondering has anyone grown heathers vertically like this? Does anyone know of any particular heather species that might do well in a wall? Many thanks.

 

Sorry never seen heathers growing on walls.

But found this link for you.http://www.ehow.com/info_7866864_heather-good-retaining-walls.html

 

Thank you very much for that information, it looks promising

 

Doesn't sound a very promising site for heathers to be honest. If it's an old wall, and has naturally been colonised by ferns, mosses & lichens as you say, then it's probably already providing a good habitat for those species (and possibly specialist invertebrates as well). Trying to plant flowers into it could potentially do more harm than good in this case.
