The Monterey pine (Pinus radiata) is an elegant plant tolerant of a range of conditions but is best suited in warmer regions. The tree is an evergreen conifer with an irregular open crown which may be vase shaped, conical or even slightly rounded. It is not a small tree and should be given plenty of space in which to grow. Learn how to grow Monterey pine trees as part of a land management and habitat program or just simply to enjoy this towering plant on your property. Monterey pines are found along the California coast but some varieties hail from Mexico. Pinus radiata has hybridized extensively with Knobcone pine and Bishop pine. This plant has a low frost tolerance and is suitable for United States Department of Agriculture zones 7 to 10. The bark is extremely attractive, being reddish brown and developing deep fissures as it ages. Needles are held in groups of three and may persist on the tree for up to 3 years. The female flowers appear as purple clusters of scales while male blooms are yellow spikes. The fruit is a cone, 3 to 6 inches (7.6 to 15 cm.) long. Cones may pose a litter problem.
