Black Locust
Golden Robinia are a popular deciduous tree to 25m. Commonly called Golden Robinia, False Acacia and Black Locust these are a deciduous tree from North America
With attractive yellow foliage in spring, Golden Robinia have been used as street trees becuase of the quick growing nature of the species.
The Mop Top Robinia is a grafted form usually grated at around 2m and it gives the classic ‘ Ball On a Stick’ appearance.
The species will grow to approx 9m, often used under powerlines. It will tolerant of poor soil and reasonably drought tolerant.
The Golden Robinia is the tree we see planted in streets across Australia. It is a tough tree that copes well with dry conditions and provides useful shade and also has attractive foliage.
Reaching around 10m in height it is fast growing, and has white fragrant flowers in spring, followed by the yellow – green foliage.
Look for R. Lacey Lady also known as the ‘Twisted Black Locust’ grafted as a standard for a very attractive small feature tree.
Problems With Robinia
However this attractive tree does have its problems, and these are mainly related to suckering and the Root system is vigorous.
The trees we see are grafted onto a vigorous rootstock which is close to the surface. It is therefore easily disturbed my mowing, digging and by line trimmers.
Once disturbed the problem of suckers arises. And as these are from the rootstock they are vigorous and thorny.
To avoid this problem, mulch around the tree rather than mow, keep well watered and remove any suckers as they appear.
With golden yellow foliage in spring Robini pseudocacia ‘frisia’ will turn to a lime green by summer.
