Pinus patula is a small or medium-sized, wide spreading, coniferous tree native to Central America but now has a global naturalised distribution. It was introduced to New Zealand for commercial purposes and is now fully naturalised here. Pinus patula can rapidly spread and invade grassland, banks, roadsides and shrubland, where they can compete with native plants, Pinus patula reproduces through small, light wind-dispersed seeds.
Pinus patula can grow to a height of 30 m or more and attains a trunk diameter up to 1.2 m. The trunk is straight and cylindrical, sometimes forked, producing 2 or more stems. The young bark is characteristically a reddish-orange colour and is scaly. The mature bark is grey-brown and vertically ridged.
It has slender, flexible, pale yellow/green, drooping, needle-like leaves which are > 33 cm long and are arranged in groups of three. Their margins that are finely toothed.
Separate male and female cones are produced on the same tree. The small male cones are elongated and are 1 cm long and are borne in dense clusters. The mature reddish-brown female pine cones are borne singly or in small clusters. The mature female cones are not persistent, asymmetrical, 6-9 cm long, and are sessile or with a short stalk.
The seeds are dark brown to almost black, very small, about 5 mm long, with a pale brown wing about 17 mm long, slightly thickened at the base where it joins the seed.
