Some plants just drop dead and die and there are others that display an amazing persistence to survive and flourish in the most unusual places. One such tree is a River Red Gum (Eucalyptus camaldulensis) which is growing out from a little crack between the pavement and the building in a suburb of Perth, WA. Probably a seed from a nearby tree blew into the little crack and germinated.
In the case of a tree growing from underneath a building it would be advisable to watch it carefully. Check that there is no cracking in the pavement or the bricks of the building. If there is cracking or a disturbance it would be best to remove the tree. Otherwise it would be safe to leave the tree to continue to amaze passers-by with its persistence.
