Gleditsia triacanthos 'Sunburst' Gleditsia triacanthos 'Sunburst'

This average-sized tree is different from the species because of its golden yellow shoots in spring. Young sprouting leaves are bright yellow, turning to green yellow during summer. The 2nd outgrowth (St. Johnslot) is strikingly yellow again. The autumn colour too, is uniformly yellow. The growth is less rapid than of the species. The crown is wide spreading when young, but when maturing more upright. Due to this capricious growth, it is perfect a park tree with a width of circa 7 m. Young twigs are golden yellow, but turn to brown green. 'Sunburst' is a spineless variety of which the compound leaf remains smaller than of the species. The tree is deep rooting with many branches and withstands hard surfaces well. Wind has a strong influence on the shape of the crown.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2025.
