Plant suggestions for tricky situation
Hi all I am looking for a plant suggestions...
I am planting a new hedge (laurel etna) up against a 6ft fence which is getting a bit dilapidated & will be replaced by the hedge. It's in a very windy site & sandy soil so even with concrete posts it comes loose over time & starts to wobble. In the mean time, in order to help the fence withstand the wind & stay erect while the hedge grows we are going to periodically (every couple of metres along a 10ft fence) remove a couple of feather edge boards to make approx 10" gaps - to allow the wind through. I feel sure this will work as is other areas of the garden where the fence sections are shorter, it remains erect without issue.
However that will leave 10" x6ft floor to top gaps all the way along & i am keen to try to regain privacy. I cant plant anything in the ground as i need the space for the hedge plants to get properly established roots & in any case if i want to screen the gaps I will need a tall pot in order to make it screen high enough up. So i was thinking to get tall narrow pots (approx 1ft wide & 2-3ft deep) & plant something as tall as possible.
I was wondering about a grass or a bamboo or a climber. But it would need to be...
a) hardy in a usual uk winter
c) happy for at least 3yrs in the pot size described
d) either 2-3ft tall itself, or if a climber (- which would be fine as i could put trellis in the fence gaps) then be established around canes or something & already grown 2-ft high.
So it would need to be something with roots that tend to grown down rather than out, i wondered about maybe a grass or an evergreen clematis. I wondered about ivy too but i've never seen an ivy to buy that wasnt quite small - you dont tend to see them already grown around canes or similar like you do with say honeysuckle or clematis.
Any ideas or thoughts very gratefully received
