View prices and availability
Grows naturally on dry rocky slopes in the mountains of eastern North America and Mexico. The loose crown is rounded and open and all parts of the tree are aromatic. The smooth bark is grey-brown, later somewhat grooved and slightly flaky. One-year-old twigs are green, older twigs yellowish-brown. The leaves are triple and fragrant. The autumn colour is yellow. The unremarkable small flowers grow in large plumes measuring up to 8 cm and have a strong scent especially in the evening. The large flattened nut fruits, measuring approx. 2 cm, grown in dense plumes and are yellowish-green. They resemble the fruit of the elm. 'Ptelea' is Ancient Greek for elm. The fruits dry on the tree and remain decorative until deep into the winter. It is an excellent forage tree, attracting many honeybees and bumblebees. Is very seldom cultivated.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
