Leaves:
Dark green, twisting, evergreen needles in pairs on short shoots. Produces a dense “irregular” canopy.

Inconspicuous tiny yellow-green flowers.

In poor and inhospitable soils the tree grows into its characteristic, twisting form. Prefers partial to full sun.

A hardy and disease resistant species. Potentially susceptible to common pine disease such as needle rust, blight and others.
