Bonnie And Mike Swamp White Oak

Quercus bicolor 'Bonnie And Mike'

The Story

Plant Bio

Quercus bicolor is a large, long-lived deciduous tree native to North America, known for its adaptability to wet soils, its distinctive two-toned leaves, and its attractive, peeling bark.

'Bonnie And Mike' is a cultivar selected for its tight, upright, columnar form, making it suitable for narrower spaces like street plantings or smaller residential landscapes where a standard oak would be too wide.

Uses & Benefits:

Ornamental UsesThe 'Bonnie And Mike' cultivar provides strong vertical structure and formal elegance. Its textured, peeling bark adds winter interest, and the two-toned leaves create a subtle shimmer in the breeze.
Practical UsesIts narrow form makes it an excellent choice for urban environments, street plantings, and residential lots where a large shade tree is desired without a wide-spreading canopy. It is also a durable windbreak.
Ecological BenefitsOaks are keystone species, supporting hundreds of species of caterpillars, which are critical food for birds. The acorns feed a wide variety of wildlife, including squirrels, deer, and jays.

Planting

How to Grow

  1. Select a location in full sun with acidic, moist soil.
  2. Dig a planting hole two to three times wider than the root ball.
  3. Place the tree in the hole, ensuring the root flare is at ground level.
  4. Backfill with the original soil, watering to settle it around the roots.
  5. Water deeply and regularly for the first two years to establish.
  6. Apply a 3-inch layer of mulch to conserve moisture and reduce weeds.

Pro Tip

Though tolerant of wet soils, it performs best with good drainage. Avoid soil compaction over the root zone.

Care Guide

Do

  • Water deeply during prolonged dry spells, especially when young.
  • Perform structural pruning in the first few years to develop a strong framework.
  • Protect the trunk of young trees from mowers and string trimmers.
  • Allow ample space for its mature height, even with a columnar form.

Don't

  • Do not plant in high pH (alkaline) soils, which can cause chlorosis.
  • Avoid wounding the bark, which can provide entry for pests and diseases.
  • Don't fertilize unless a soil test indicates a specific deficiency.
  • Never top the tree; it ruins its natural form and health.
