Northern Pin Oak

Quercus ellipsoidalis

Northern Pin Oak is a medium sized deciduous oak for sunny well drained sites. It provides shade and wildlife food and tolerates dry sandy soils once established.

Key Facts

  • Deciduous oak in the red oak group with bristle tipped lobed leaves.
  • Native to the upper Midwest and Great Lakes region of the United States.
  • Medium sized shade tree commonly used in parks and larger yards.
  • Prefers well drained sandy to loamy soils and tolerates dry sites.
  • Performs best in full sun but will tolerate some light afternoon shade.
  • Produces acorns that provide food for birds and mammals.
  • Moderately drought tolerant once established.
  • Propagation is commonly by acorn seed or by nursery-grown transplants.

Northern Pin Oak is a medium sized deciduous oak used for shade in parks and larger yards. It performs best on sunny well drained sites and is valued for wildlife food and moderate drought tolerance once established.

Identification

This oak belongs to the red oak group and has bristle tipped lobed leaves and acorns. Mature trees commonly reach about 30 to 50 feet tall with a crown spread often about 20 to 40 feet. Flowers are inconspicuous spring catkins rather than showy blooms.

Where to grow and landscape uses

Use Northern Pin Oak as a specimen shade tree in parks and larger yards where there is room for a moderate crown. It is native to the upper Midwest and Great Lakes region so it suits temperate northern landscapes within its hardiness. The tree is not appropriate for small tight spaces or small container growing.

Soil and light requirements

Plant in well drained sandy to loamy soils and avoid heavy poorly drained clay for long term health. The oak prefers acidic to neutral soil and gives best form in full sun while tolerating light afternoon shade. Trees on drier sandy sites often remain smaller but survive with less supplemental watering.

Planting and establishment

Plant nursery transplants in a spacious site with good drainage so the root system can develop. Keep soil evenly moist through establishment because the tree only becomes moderately drought tolerant after roots are established. Avoid sites with prolonged wet feet where root decline may occur.

Watering and maintenance

Once established Northern Pin Oak tolerates moderate drought and typically needs less frequent irrigation than shallow rooted ornamentals. Monitor newly planted trees and water during extended dry periods so roots can develop. Avoid compacting soil around the root zone and remove dead wood to maintain tree health.

Wildlife value and toxicity

The tree produces acorns that provide food for birds and mammals and supports wildlife in landscape settings. Acorns and foliage contain tannins that can be toxic to livestock if consumed in large amounts and may cause gastrointestinal upset in small pets. Severity depends on species size and quantity eaten.

Propagation

Propagate from acorns with cold stratification or use nursery grown transplants and grafting for selected clones. Collect acorns fresh and store cold prior to stratification to improve germination. Nursery transplants provide the most predictable results for landscape planting.

Frequently asked questions

How fast does Northern Pin Oak grow?
Growth rate varies by site and soil. Trees in fertile well drained sites grow faster and reach the typical 30 to 50 foot height while those on poor dry soils grow more slowly and often remain smaller.
What hardiness zones will it grow in?
Northern Pin Oak is reported as adapted to USDA hardiness zones 3 through 7 and suits northern midwestern climates within that range.
When does it flower?
Flowers are inconspicuous wind pollinated catkins that appear in spring often around April and May in the northern hemisphere rather than showy blooms.
Are the acorns safe for pets and livestock?
Acorns and foliage contain tannins that can be toxic to livestock if eaten in quantity and may cause vomiting or diarrhea in pets. Risk depends on animal species size and amount consumed.
Can I grow Northern Pin Oak in a container?
Because mature trees commonly reach 30 to 50 feet with a 20 to 40 foot crown this species is not suitable for long term container culture and needs space to develop a full root system.
