Hi,
I am not particularly green fingered but have bought various plants for the garden over the past few years , the prices are probably like for like but the plants that tend to thrive here are those that are more native to the soil and climate conditions . Pot plants in my experience are a disaster here unless watered twice a day in the summer months even things like mint / rosemary can die overnight ! I would wait until you get here and suss out what’s in your neighbours garden !
Also when we moved over Pickfords managed to break pretty solid items so can’t see ornamental plants taking the journey , best of luck .
