Globe acacia
The globe acacia (Robinia pseudoacacia 'Umbraculifera'), also known as the spherical locust, has a clear geometric shape that lends itself well to entrances, walkways, or small gardens. The dense, richly branched crown also creates a beautiful appearance in containers on the patio. Since the trunk is branch-free up to the base of the crown, allowing sufficient light to reach the ground, it can be underplanted at the base.

Growth form
It is one of the most commonly chosen spherical trees and is usually grafted to a tall trunk. The crown is compact and spherical, flattening with age to a rounded, umbrella-shaped shape—hence the Latin name umbraculifera, meaning "umbrella-bearing." The final height is approximately 4 meters, and the crown is about 3 meters wide.
leaf and flower
The globe acacia is adorned with delicate, deciduous foliage, odd-pinnate and borne on short stems. It does not flower and therefore does not produce fruit. The upper surface of the leaves is blue-green, while the underside is light green. The shrub sprouts relatively late and also begins shedding its leaves relatively early.
Site requirements/care measures
The globe acacia is completely undemanding. However, it enjoys a sunny location that provides warmth and some protection from strong winds. It's particularly easy to care for soil, as it will also grow in dry, sandy soils. However, if you really want to do it a favor, plant it in loose, oxygen-rich soil where it can also overwinter well. It only needs pruning every few years to keep its crown nice and dense; it won't resent this.
