Lone poplar

This huge poplar is growing in our house paddock. We planted this when we were first married, on the site of our then rubbish tip! That has since been filled in andwe now have our rubbish collected once a week, although there is a huge graveyard for old fencing wire and cars and sheets of metal in the middle of the property.
This was supposed to be a non suckering tree and for years it was but with the chemical weedspraying that is now done I notice that a few suckers come up now and then. They dont last long as the cows eat them.
