Great shot Patricia, I wish I was there!

Thyme is great for small leaves,bonsai need to be in pots so might grow too big in the ground.SOme minaiture conifers could be good though , they have smallish leaves and don't grow over big, they are slow growers too.Another one that could be kept small is golden diosma, its leaf size is really small and can be cut down to really small bush size as well as nice rounded humps too.
What about Sacred Bamboo?Have forgotten it's proper name , Lovely red leaves, a smallish size and also not a big grower and can be kept cut back if needed.
Jade bush?(I have plenty if you want some?)
