Learn the Latin name.
A zucchini and some pumpkins are the same species. A cucumber and a watermelon aren't. Common names can lead you astray.
THE SEED SAVING LAB / FIELD EDITION 01
What happens when your garden shares pollen?
A zucchini beside a pumpkin. Two colors of zinnia. A cabbage near a flowering kale. Explore the invisible relationships in your garden—and what they mean for next year's seeds.

01 / THE EXPLORER
A LIVING FIELD GUIDEWill these two plants cross?
Start with your plants. The botanical species—not how similar they look—is the first clue.
THE FIELD ASSESSMENTRESEARCH-BASED • NOT A GENETIC TEST
✣
Every seed has a history.
Choose two plants and discover whether they might exchange pollen, what that could mean for your seeds, and how to protect—or explore—the next generation.

A separation guideline is not a measured probability of a cross. Pollinators, landscape and neighbors matter.

02 / THE WHOLE-GARDEN VIEW
LOCAL · NO ACCOUNTWhich seed crops need protection this season?
Add your vegetables, herbs, and flowers. See all possible pollen pairings at once, then take a garden-specific preservation plan into the field.
YOUR GARDEN · 0 / 12 plants
Mark whether each variety is flowering now. This is a snapshot, not proof that flowering periods never overlap. Unknown bloom information is treated conservatively. Nearby gardens and wild relatives are not in this list.

03 / THROUGH THE GENERATIONS
The seed is not the end of the story.
Move forward in time to see what a possible cross—or careful preservation—could mean. This is a qualitative guide, not a prediction of exact traits.
GENERATION01
What could grow next year?
Run an analysis above to connect this timeline to your plants. A cross can introduce variation; repeated selection can preserve or change a population over generations.
Illustrative generation pathway only • No phenotype percentages or guaranteed outcomes04 / FIELD NOTES
Three rules worth carrying into the garden.
Separate flowering—not just plants.
Crossing needs compatible pollen and receptive flowers at the same time. Distance, timing, bagging, and controlled pollination change the situation.
Protect diversity.
Saving from one favorite plant may keep an interesting trait, but long-term preservation also depends on adequate population size and thoughtful selection.
Usually, cross-pollination affects the next generation grown from saved seeds, not the current tomato, squash, or flower's appearance. Corn kernels are a notable exception. Read the University of Minnesota explanation ↗
THE BIGGER EXPERIMENT
One explorer. An entire Seed Saving Lab.
The long game is knowing which seed lots deserve a place in next year's garden, what those seeds preserve, and what they might become.
