Discussion | Pinus rigida often has poor form and is not valued highly as saw timber. It is fire successional, sprouts adventitiously, and is frequently shrubby in the northern part of its range. It is known to hybridize naturally with P. echinata. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
