Overcup Oak

Overcup Oak (Quercus lyrata)

Overcup Oak is a standout choice for landscapes that deal with heavy soils and periodic wetness, offering true oak presence without demanding perfect conditions. It develops into a strong shade tree with a broad canopy that makes outdoor spaces cooler and more comfortable in summer. If your site has low spots, seasonal puddling, or clay that stays damp, this oak can be a practical solution that still looks timeless. Once established, it becomes a dependable, long-lived canopy tree with real landscape value.

Distinctive Features

This native oak is known for its distinctive acorns, where the cap can cover most of the nut, giving it the name Overcup. The foliage is medium to deep green through summer, and fall color is typically yellow to brown, sometimes with muted bronze tones. It forms a sturdy trunk and a rounded crown, creating classic shade tree structure as it matures. Its natural tolerance for wetter conditions helps it thrive where many traditional shade trees struggle.

Growing Conditions

• Sun: Full sun is best for canopy density and overall vigor.
• Soil: Prefers moist soils and performs well in heavier clay, including sites with periodic flooding.
• Water: Keep evenly moist during establishment, then it tolerates wet conditions and benefits from occasional deep watering during drought.
• USDA Zones: 5 to 9.
• Site: Ideal for low-lying areas, swales, and spots that hold moisture longer than the surrounding landscape.

Ideal Uses

• Focal Point: Use as a specimen in a larger lawn where its canopy and unique acorns can be appreciated up close.
• Problem Area Shade: Plant to create shade in damp or heavy-soil locations where other large trees decline.
• Rain Garden Edges: Place near swales, pond margins, or drainage corridors to add canopy and stability.
• Wildlife Value: Include in naturalized areas to support birds and mammals that rely on acorns and canopy cover.

Low Maintenance Care

• Watering: Water regularly in the first one to two seasons, especially during hot stretches, even if the site stays generally moist.
• Mulching: Mulch to reduce competition and moderate soil moisture, keeping mulch a few inches away from the trunk.
• Pruning: Prune in dormancy to develop strong structure and remove damaged or crossing branches.
• Establishment: Avoid soil compaction around the root zone to help the tree settle in and expand roots efficiently.

Why Choose Overcup Oak?
