Species:
Family:Myrtaceae
This evergreen shrub features an upright growth habit with elongated, gently branching stems. It can be cultivated indoors as a houseplant or used outdoors as an attractive woody shrub or small tree.
It is resilient to drought but is highly susceptible to dieback, as it struggles to adapt to colder temperatures.
While it is toxic only in significant amounts, skin irritation may occur, though it is typically minor and lasts only a few minutes.
