Common name lemon gum tree
Family myrtaceae
Life cycle tree (Z8-11)

Broadleaf evergreen tree from Australia. Becomes quite tall in its native habitat, and grows fast enough that it can be treated as an annual shrub in colder areas. Here in Houston, it is likely to survive most winters, and may even grow mature enough that we can see its small white flowers and the white bark that develops with age. The leaves are grayish-green, hairy and lance-shaped, and are strongly lemon-scented.
We got our specimen in April 2018, as a wispy thing perhaps two feet tall. Once it settled into a freshly dug bed in our back yard, it wasted no time zooming upwards, and reached well above man height by late summer.

Interesting growth pattern: the trunk grows straight upright, with small branches coming off in a very regular alternating pattern. The lower branches die off as the tree grows, eventually breaking free right where they attach to the trunk, leaving a row of holes/scars going up the tree. The following year, in early spring, our tree started shedding its papery bark (making a bit of a mess of its environs). The bark has a reddish-tan exterior and a white interior, while the trunk revealed underneath is creamy-tan.
