..That plant is awesome, girth, height,weight...love it, mine will not be as large even in a few years.
Gotta ask.....I see some retaining walls. so I suspect you are on a mountain or big ol hill.
What is your sunlight situation... in the front garden area.
Still love those rocks.......they rock. I have rock shelves in the garden ....but not like yours.
Stones that size for the landscape totally create your space.
