PINUS - Pine 
In economic importance the Pine stands above all evergreen trees. It grows in a 
wide variety of soils and under a broad range of climatic conditions. It will not, 
however, endure shade, smoke, or an excess amount of dust. It prefers the open 
country, hillsides, and sandy slopes. Will withstand considerable drought and 
flourish on poor soil. Except for a few dwarf varieties, they are adapted for mak- 
ing groves, forests, windbreaks, backgrounds, and specimens. They are very useful 
for reclaiming waste land and will thrive anywhere if the soil is well drained.
