You could consider deepening the bed by forming a raised bed. Build a wall with either treated timber e.g. railway sleepers, or building blocks or even a drystone wall.
I think I would go for smallish shrubs look in here for ideas;

Quite often root depth is relative to plant height, hence the reason for me suggesting 'small shrubs'.
I would not select shrubs that require acidic/ericaceous conditions the cement in the tank will have probably raised the alkalinity of the area.
I hope this helps!
