Swamp White Oak

$9.35 $11.00

Dont' let the name fool you! Swamp White Oak is a widely adaptable tree, thriving in medium soils as well as wetter soils, growing tall or spreading wide depending on the conditions it's in. Juvenile trees often have dark, shaggy bark that lifts and curls like papery birch bark. This quality shifts to rough, ridged furrows in gray-brown bark on more mature individuals. The branches tend to be more smooth, and twigs feature raised, white, scar-like lenticels. Leaves are a leathery, dark green with fairly uniform size, shape, and lobing.

In early spring, male and female flowers bloom in tan-yellow and light green shades, allowing the tree to cross pollinate. Fertile female flowers produce acorns that emerge from gray, fringed caps. Fall brings earthy tones to the leaves, often showcasing a burnished amber color, sometimes with small pops of burgundy. 

This tree prefers to be in full sun, but will tolerate a range of light conditions. Because the root system is shallower and more widespread than other oaks, Quercus bicolor thrives in wet areas, often seen on the edge of vernal ponds and riverbanks. It handles temporary flooding, compacted soil, and roadside salt, making this Oak a good choice for a wide boulevard. This tree adapts to most soil conditions, unhindered by clay, loam, gravel, etc - but it does require a more acidified soil to maintain good health. 

Swamp White Oak is a haven for a host of insects, including several leafhoppers, beetles, Hairsteak butterflies, Duskywing skippers, and a variety of moths. The acorns are an important food source for Wood Ducks, Ruffed Grouse, several types of Woodpeckers, as well as mammals like Black Bear, Racoons, and Squirrels.

*Tree whips that are 1-2 years old, such as this Oak bare root, will benefit from being placed in tubing or behind wire caging to protect it in the early years from deer and other small mammals. Read more about How to Plant an Oak.

2 Questions asked on Quercus bicolor

How susceptible is this variety to Oak Wilt?
It is common for species in the Red Oak sub-family to be the most susceptible to oak wilt. This would include the Quercus rubra (Red Oak.) Species in the White Oak sub-family are the most resilient to the disease. These include Quercus bicolor (Swamp White Oak), Quercus macrocarpa (Bur Oak), and Quercus muehlenbergii (Chinquapin Oak.) Also it is important to remember that oak wilt is a disease that impacts older adult trees!
I would like to plant this so that it doesn't encroach on my neighbor's property. The plant spacing is 20'-30', but what is the mature width?
Hello Robin, 20'-30' width spacing would be accounting for when the tree is mature. To be safe it may be a good idea to plan for extra growth and plant 40' to 50' away from your neighbors property line. The roots will expand as time goes on, This will leave some "wiggle room" just in case. I hope this helps.


Growing your own plants from seed is the most economical way to add natives to your home. Before you get started, one of the most important things to know about the seeds of wild plants is that many have built-in dormancy mechanisms that prevent the seed from germinating. In nature, this prevents a population of plants from germinating all at once, before killing frosts, or in times of drought. To propagate native plants, a gardener must break this dormancy before seed will grow.

Each species is different, so be sure to check the GERMINATION CODE listed on the website, in the catalog, or on your seed packet. Then, follow the GERMINATION INSTRUCTIONS prior to planting. Some species don't need any pre-treatment to germinate, but some species have dormancy mechanisms that must be broken before the seed will germinate. Some dormancy can be broken in a few minutes, but some species take months or even years.

Seed dormancy can be broken artificially by prolonged refrigeration of damp seed in the process of cold/moist STRATIFICATION. A less complicated approach is to let nature handle the stratifying through a dormant seeding, sowing seeds on the surface of a weed-free site in late fall or winter. Tucked safely beneath the snow, seeds will be conditioned by weathering to make germination possible in subsequent growing seasons.

Dormant Bare Root Plants

We dig plants when they are dormant from our outdoor beds and ship them April-May and October. Some species go dormant in the summer and we can ship them July/August. We are among the few still employing this production method, which is labor intensive but plant-friendly. They arrive to you dormant, with little to no top-growth (bare-root), packed in peat moss. They should be planted as soon as possible. Unlike greenhouse-grown plants, bare-root plants can be planted during cold weather or anytime the soil is not frozen. A root photo is included with each species to illustrate the optimal depth and orientation. Planting instructions/care are also included with each order.

Potted Plants

3-packs and trays of 32, 38, or 50 plants leave our Midwest greenhouses based on species readiness (being well-rooted for transit) and order date; Spring shipping is typically early May through June, and Fall shipping is mid-August through September. Potted 3-packs and trays of 38 plugs are started from seed in the winter so are typically 3-4 months old when they ship. Trays of 32/50 plugs are usually overwintered so are 1 year old. Plant tray cells are approximately 2” wide x 5” deep in the trays of 38 and 50, and 2.5" wide x 3.5" deep in the 3-packs and trays of 32; ideal for deep-rooted natives. Full-color tags and planting & care instructions are included with each order.

Shipping & Handling Charges

SEED $100.00 and under: $5.00
Retail SEED orders over $100.00 ship free!

Custom seed mixes or discounted seed sales over $100, add 5% of the total seed cost
(for orders over $1,000 a package signature may be required)

BARE ROOT and POTTED PLANTS $50.00 and under: $9.00
over $50.00: 18% of the total plant cost. (For orders over $1,000 a package signature may be required.)

TOOLS and BOOKS have the shipping fee included in the cost of the product (within the contiguous US).

**We are required to collect state sales tax in certain states. Your state's eligibility and % will be calculated at checkout. MN State Sales Tax of 7.375% is applied for orders picked up at our MN location. Shipping & handling charges are also subject to the sales tax.

Shipping Season

SEED, TOOLS and BOOKS are sent year-round. Most orders ship within 1-3 business days.

BARE ROOT PLANTS are shipped during optimal transplanting time: Spring (April-May) and Fall (Oct). Some ephemeral species are also available for summer shipping. Since our plants are field-grown, Nature sets the schedule each year as to when our season will begin and end. We fill all orders, on a first-come, first-serve basis, to the best of our ability depending on weather conditions beyond our control.

POTTED PLANTS (Trays of 32/38/50 plugs and 3-packs) typically begin shipping early May and go into June; shipping time is heavily dependent on all the species in your order being well-rooted. If winter-spring greenhouse growing conditions are favorable and all species are well-rooted at once, then we ship by order date (first come, first serve). We are a Midwest greenhouse, and due to the challenges of getting all the species in the Mix & Match and Pre-Designed Garden Kits transit-ready at the same time, we typically can't ship before early May. Earlier shipment requests will be considered on a case-by-case basis.

*We are unable to ship PLANTS (bare root or potted) outside the contiguous US or to CALIFORNIA due to regulations.


We ship using USPS, UPS and Spee Dee. UPS and Spee Dee are often used for expediting plant orders; they will not deliver to Post Office Box numbers, so please also include your street address if ordering plants. We send tracking numbers to your email address so please include it when you order.
