Growing with obstruction

Hi all..

We have a flower bed in the garden which is surrounded on two sides by an old stone wall.  The concrete foundation of the wall isn't very deep and so I wonder if we'll be able to grow foxgloves, as planned, along the wall.  There's probably only about 6-8" of soil before the concrete, which comes out a good foot from the wall itself.  Will the roots find a way, or will the small plants just die when it hits the concrete and doesn't know where to go?

Also, I worry that if the roots do find a way they'll either make it harder to grow things in front of them, or (less likely I'm sure) damage the wall.

Any thoughts?

We have considered getting some large pots but this is not ideal..

Thanks in advance!

I let foxgloves selfseed ON a stone wall that is on one side of the garden.They grow in the little soil thats between the stones and do quite well and are beautiful so your'e situation should be a doddle for them

Yes - foxgloves should do ok. I have them self-seeding under a very large Sycamore tree in dry shade. Also, if you look at the tap roots of some dandelions, they can be bent due to growing towards where the moisture is, though I don't think they have a tap root as far as I know.

".........foxglove is not easy to transplant, due to its extended tap roots".

Other sites on the internet, contain this information.

I start all my cultivated foxgloves in a tray and prick them out into 3inch pots ,grow them on for a month /6 weeks and then plant in final planting position and they do well

Thanks all - I'll give it a go and report back (if I remember!!)
