Pin oak, Swamp Spanish oak


Fagaceae (Beech Family)



Quercus palustris (Pin oak)
Flaigg, Norman G.
Straight-trunked tree with spreading to horizontal branches, very slender pinlike twigs, and a broadly conical crown. Pin oak is a stongly pyramidal tree with a distinct central leader, growing 60-70 ft. or taller. Instead of the gnarled, massive qualities of most oaks, pin oak has a more graceful, slender appearance. Old trees become high-crowned after shedding lower limbs. Dark-green foliage becomes dark-red in fall. Leaves persist into winter.

Named for the many short side twigs or pinlike spurs. A popular, graceful lawn tree with regular compact form and fine-textured foliage, Pin Oak is hardy and easily transplanted because the shallow fibrous root system lacks tap roots.

Conditions Comments: One of the faster growing oaks. Tolerates wet feet. Intolerant of alkaline soils. Susceptible to iron chlorosis which causes yellow coloration in the leaves through the summer months and can eventually kill the tree. Somewhat tolerant of city conditions. Pin oak is shallow-rooted and easily transplanted, and it will tolerate urban conditions in areas well outside its natural range (Kershaw).
