Will these plants cross?
A zucchini leans toward the pumpkin patch. A bee works them both before noon. The fruit looks the same in September, but the seed remembers. Tell me what you are saving seed from and what blooms near it, and I will tell you plainly what that bee may do.
Check two plants
Which of my plants can cross?
Name what is growing this year. Every pair gets checked, the way you would walk the rows in late July with a bee on every blossom. The web shows who can reach whom, and the chart shows how much room each crop needs to stay itself.
Green seed: saving seed from it. Tap the seed on anything you only eat, and pairs with nothing at stake step aside.
Pollen web
Each line is a path a bee could carry pollen along. Tap a plant to see its partners, or tap a line to open that pair.
A season, told in seed.
Every saved seed carries a little of the summer it grew in. Here is how that story gets written, one flower at a time.
- Early summer
The bloom
A flower opens and offers two things at once: pollen to give and a place to receive it. What arrives in those few days decides what the seed will carry.
- High summer
The visit
Bees and wind do not read seed packets. They read botany. Pollen moves easily between plants of the same species and almost never between different ones, whatever the common names suggest.
- Late summer into fall
The seed
The fruit on the vine looks just as it should. A cross hides inside the seed, where you cannot see it yet. Sweet corn is the one exception gardeners notice right away, in the kernels on the ear.
- Next spring
The telling
Plant it out and the story comes back. Kept apart, the variety returns as itself. Crossed, it may bring something new. Saving from many plants, not just the best one, keeps the line strong for years.

A field guide, not a crystal ball.
Every answer here rests on published horticultural references for species, flowering, pollination and isolation. This explorer does not calculate a percentage chance of crossing, guarantee purity, or predict what a seed will become from its variety name. A separation guideline is not a measured probability of a cross. Bees, wind, the shape of the land and the garden next door all have a say, and a good gardener keeps watching.
