About plant names...

Red pines are native to northeastern North America. They live for 200-400 years.

Identification: These trees typically reach 50-70' (15-21 m) tall, sometimes up to 200' (60 m). Bark is rough and scaly and silvery gray, peeling easily to reveal orange-red or brown bark underneath. Needles are 4-7" (10-17 cm) long, medium green, occurring in groups of two. Flowers are inconspicuous. Cones are light brown, oval in shape, about 2" (5 cm) long, occurring singly or in pairs. Needles snap easily when bent, an identifying feature. I am perplexed by the spherical bulges on the shrub-sized pine in photo 14.

For further information, see the Pinus comparison tables.
