Hello all -- I want to replace a Silver Birch tree that I have in my frontyard. Because of the drought, it's looking very sad at the moment - plus silver birch is not really that suitable for the Adelaide plains area. I want to plant a wide-canopied plant, similar to jacaranda or a honeylocust tree but I read that their roots are very invasive. The spot is open to direct sunlight, and about 5 metres from the house, and about 2.5 metres from the sewer line. Can anybody recommend an open-canopied tree that would grow to a nice height (about 5m+) that can provide nice shade over the frontyard and without an invasive root system please? Ideally I would like a deciduous tree, but if it's a nice evergreen tree, I will make a concession for it. :) Japanese maple is a possibility but the dry hot wind in summer burns the leaves and liquidambars are notorious for having a very invasive root system. Adelaide has Mediterranean climate with alkaline soil. Any suggestions please? Thank you!
