Lycianthes rantonnei (blue potato bush)
I'm planning to plant Lycianthes rantonnei in our side yard to hide the ugly side of a Bird of Paradise growing in the neighbors' yard. I know it is easy care and loves the sun and can get very big.
I'm wondering how much space to allow it to grow full size in southern CA. I had one in the front yard that was too big for the space (before I knew better) and needed almost weekly pruning. I want to let this one go to full size.
Will 8 feet on each side be enough? It will be near the drip line of a well-established (at least 25 years old) tangerine tree, but not touching the tree.
