This highly ornamental as well as most useful genus comprises about seventy species indigenous to most of the North Temperate Zone and contains many exceedingly ornamental and picturesque trees for landscape improvement. Pinus insignis (the Monterey Pine) by many authorities is considered to be the most ornamental of all the species either native or foreign. Another native, Pinus Lambertiana (Sugar Pine) is without doubt the most gigantic of all. The Pine is not particular as to soil provided it is well drained, although there are some, such as Pinus Murrayana and Pinus rigida, which prefer a wet or swampy situation.
California is very rich in varieties of this genus, no less than sixteen species being indigenous to this coast.
A Group of Pines.
Among the most desirable foreign species may be included Pinus Cembra, Pinus halepensis and Pinus Pinea (the Italian Stone Pine) perhaps the most picturesque species of the genus. This Pine prefers a sandy soil and a seaside sheltered situation.
Propagate by seeds sown, in March or April, from one-quarter to one-half an inch deep (according to the size of the seeds) in a cold frame. When the young seedlings are two or three inches high, they should be placed in nursery rows in the open ground, and, when from twelve to eighteen inches high, should be planted out in their permanent quarters in Winter.
