Robinia x ambigua is a hybrid between R. pseudoacacia and R. viscosa. It has many similarities with R. pseudoacacia but its leaves are slightly smaller. The sticky, young twigs are characteristic of R. viscosa. 'Bellarosea' is a small tree with an elegant shape. The crown is rounded and open. Unlike R. x ambigua, 'Bellarosea' has branches bearing strong thorns. The imparipinnate leaves are about 24 cm in size and consist of 13 - 21 elliptical green leaf segments. Pendulous, loose clusters of large pink flowers appear in June. The flowering period lasts into August. The branches are breakable; inclement weather conditions can cause branches to break particularly when the tree is in full bloom. Consequently, a site sheltered from the wind is required. Robinia xambigua is not very sensitive to road salt and tolerates paving well.
