Robinia pseudoacacia 'Umbraculifera' is commonly known as False Acacia 'Umbraculifera' is a small tree with a spherical ball of foliage which you can keep trimmed to give an attractive shape. It is always grafted onto a stem, which gives it height, great for architectural planting along walkways or to beautify an entrance way. Other than trimming to keep the shape, they require very little maintenance. It has been in cultivation since 1800 and is commonly seen in public places due to its' good looks and low level of maintenance. It survives in the urban environment well and tolerates most soil types.
