Crataegus ×grignonensis – Red-thorn

View prices and availability
This cross between C. crus-galli and C. pubescens grows into a small tree approx. 6 m tall with a dense and broad vase-shaped crown. The greyish-brown branches are practically without thorns. The oval to ovoid leaves have 2 - 4 lobes and are slightly leathery. The upper side is dull dark green, the underside light green. In the autumn the leaves remain a long time on the tree, often until well into December. White flowers in umbels appear in May and June. They are followed by glossy reddish-brown fruits approx. 1.5 cm in diameter. They stay on the tree until the first frost. The tree needs good anchoring because of its weak root system. Preferably on wind-free sites in parks and small streets.
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.
