Pinus massoniana aka Masson Pine

Pinus massoniana, or Chinese red pine, is an evergreen tree in the pine family, Pinaceae. It comes from central and southeastern China. Its wider recorded range includes Taiwan, Hong Kong, and Vietnam. It grows on plains, hills, and mountains. Its habitats extend from near sea level to higher mountain slopes. The tree reaches about 82 feet (25 metres) tall. Its year-round foliage makes it a lasting part of the woodland canopy.

Each tree carries both male and female reproductive structures. Wind moves the pollen between trees. PFAF describes the species as not self-fertile. It also reports that seedlings from self-fertilized seed tend to grow poorly. Seeds ripen from January to February. This is a seed-ripening period, not a stated flowering season. The supplied species evidence gives no further details about cone shape or bark.

Give this pine an open site with direct sun. It does not grow in shade. It suits sandy or loamy ground with good drainage. A light sandy or gravelly loam meets its needs. It can grow in poor soil with few nutrients. Mildly acid to neutral soil suits it. Avoid sites where water drains poorly. It accepts dry or moist ground, and established trees withstand drought. PFAF lists USDA hardiness zones 6–9. Its large size suits a woodland canopy setting.

This species is an important timber tree in Asia. Its needles provide tan or green dyes. A vanillin flavouring can come from by-products of pulpwood processing. This use does not establish that any raw part is edible. PFAF records traditional uses of the leaves for rheumatism and intestinal parasites. It also records medicinal uses for pollen. These reports describe past uses, not proof of safe treatment. Needle secretions can hinder seed germination, which may limit plants growing beneath the crown.

Seed offers a means of propagation. Sow fresh seed in separate pots in a cold frame. Stored seed may benefit from six weeks of cold treatment at 39°F (4°C). Move young trees to their final site while still small. PFAF recommends planting at 1–3 feet (0.3–0.9 metres) tall. Protect young plants through their first one or two winters. Early planting helps avoid problems linked to their sparse roots.
