Jardín Salamanca, lavender garden before it blooms, green textures, by Estudio Paisajismo
You can grow an olive tree in a concrete planter on a deck. They're really hardy, don't mind heat generated by their pot and don't require insects to pollinate them. I've had one for 16 years in a terracotta pot and although the pot keeps it small, it still rewards me with enough olives to brine for my pantry.
