Pinus longaeva (aristata)

Pinaceae - Pine

Twigs/buds: Twigs orange-brown, becoming black when older.  Buds 1/3" long; covered with brown scales.

Flowers/fruit: Monoecious.   Fruit a woody cone; short stalk; about 3" to 3-1/2" long; brown; scales thick and tipped with a long bristle; seeds smaller than limber pine and winged.

Bark: Thin, smooth, and gray-white on young stems; furrowed and red-brown on older stems.

Wood: Unimportant; fairly soft; heartwood light red-brown.

General: Native in scattered mountainous areas in the interior West, including Utah.  Slow growing and very long-lived (over 4,000 years old) on dry, tough sites.  Shade intolerant.

Landscape Use: Seldom used but should be more often; can be found at nurseries; very slow-growing; nice dark green color and interesting, sometimes contorted form; needs little or no supplemental water once established.  Zones 5-7.  Used to be named Pinus aristata; Welsh et al. consider the bristlecone pine growing in Utah and farther west to be P. longaeva, with P. aristata found in Colorado.

Cultivars: 'Sherwood Compact'.
