Hola Liz
Yeah they are in the ground already

We have a back garden that butts up to the track so the plan was to have a Cacti garden there as the Cacti are not child friendly but the garden we have made for them is fine, you can't fall onto it if you know what I mean!
We had started the garden and had an Aloe Vera, 2 palm trees and a funky Cactus, we have added your lot to one side of the garden as we want to cover it, great for security also and this back garden is the only way to our back door from this side

When I have a laptop I will take some images and post them (I left my laptop in the rain!)
