we have three of the E. ficifolia in our yard (about 50yrs old). it was planted above a raised masonary block retaining wall (~3ft high) about 7 ft from the retaining wall. the retaining wall has not suffered any damage from the roots. So I do not think it's a high-root-damage tree as long it has alternative areas for the roots to grow (in our case, in the direction along and away from the retaining wall).

THey grow relatively quickly when they're young, but once it reaches about 25-30ft, they seem to slow down and didn't grow much taller. When healthy, the canopy is dense dark green, and when it flowers it's spectacular, and buzzing with honey bees and humming birds. If you want to attract honey bees, this tree is it. when you go near it when it's flowering, sometimes... read more

While this tree is very showy when in flower, it should not be planted as a street tree. The flowers drip large amounts of nectar on cars and sidewalks, Then the large woody seed pods are a hazard to cars when they drop, and to pedestrians who might trip on them.
It should be used only in gardens and parks.

Very beautiful flowering Gum. I have 2x growing in my garden, and this is there second winter coming up ~ all good so far.
The hardiness zones that are posted for this tree are incorrect by miles.
This tree is only hardy to zone 9a, and would most likely be killed if temperatures drop much below -7c or 19f.

This is a very common avenue tree in some cities in Southern California. It has to be one of the most colorful of the Eucalyptus. It is an easy grow here and extremely drought tolerant. Very messy tree, though... not easy to plant stuff under it as it has deep shade, tons of falling leaves, bark and branches, and very sappy.
