How complete this information is
The safety information on this page is partial. Where a source covers a point, it is shown; where none does, the page says so.

Toxic to pets
No ASPCA entry found.

ASPCA index has no Pinus edulis page; other pine pages (if any) are not a verdict for this species. Do not treat as pet-safe.

PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.

Care

Hardiness zones

USDA 6a-8b per NC State Plant Toolbox; USDA 4-8 per Utah State Extension

Light

Full sun per NC State; shade intolerant per Utah State.

Water needs

low low is a plain-language reading of NC State (resistant to drought and dry soil; good drainage only) and Utah State (grows on dry sites). Utah State says pinyons in housing developments often do poorly from over-watering and root damage. A humid-climate yard is a poor match; finger-test two inches down.

Mature size

NC State: 10-20 ft tall and 12-36 ft wide; available space more than 60 ft
