Fruit and veg plants, planters etc (Garston)

Hi all - I work in a Deaf school in St Albans - we have a outside courtyard dining space that is quite concrete looking to bring nature into it with lots of fruit and veg plants and suitable garden reno to make it feel like a special place to learn how to grow food, nice place to eat or even read a book. Any plants, pot or troughs welcome ! Thank you in advance!
