Swamp Tupelo Tree Seeds (Nyssa sylvatica var. biflora)

Swamp Tupelo Tree Seeds (Nyssa sylvatica var. biflora)

Wetland warrior. Crimson in fall, steady in flood.

Nyssa sylvatica var. biflora, the Swamp Tupelo, is a tough and beautiful native tree built for the extremes of the southern landscape. Found in wetlands, bayous, and floodplains, it thrives where other trees falter—rooted in water yet graceful in form. Its glossy green leaves shift to deep crimson and purple in fall, offering a stunning show above mirrored waters and marshy ground. Perfect for erosion control, wildlife habitat, and wetland restoration.

  • Native to the southeastern United States
  • Exceptionally flood-tolerant and ideal for wet, low-lying areas
  • Brilliant red to purple fall color and glossy summer foliage
  • Provides nectar for pollinators and fruit for birds and wildlife

FAQ

Do you pre-stratify the seeds?

Most of our seeds are not pre-stratified. We ship them unstratified so you can control germination timing based on your local growing season. We sell to all 50 U.S. states and Canadian provinces, and since each region has different planting windows, pre-stratifying would risk seeds germinating in transit or before you're ready to plant.

True stratification requires cold, moist conditions, which can lead to premature sprouting or mold if not timed properly. To avoid this, we store most seeds in dry cold conditions to preserve viability — but this does not initiate stratification.

Do any of your seeds need to stay moist? (Recalcitrant seeds)

Yes — some species we offer are recalcitrant, meaning they must remain moist to stay viable and cannot be dried out. Examples include: Chestnut, Hazelnut, Paw Paw, etc.

These seeds are shipped in moist cold storage and are clearly labeled on the product page when applicable. Please refrigerate immediately upon arrival and follow included care instructions.

Do you ship internationally?

We currently ship to the United States and Canada only. Unfortunately, we cannot ship to other countries without a phytosanitary certificate, which is required by most international customs agencies.

If you're interested in shipping outside North America, please contact us. Note that a phytosanitary certificate typically adds $60–$80 USD per seed type and must be arranged in advance.
