Cross-Pollination Guide
From Ice Age Farmer Wiki
| Vegetable Crop | Will Cross-Pollinate With |
|---|---|
| Asparagus | Wild Asparagus |
| Beans | Self-pollinating; very small chance of different species (runner, yardlong, lima, etc.) cross-pollinating. |
| Beets | Readily crosses with any Beta vulgaris species: Swiss chard, leaf beet, spinach beet, etc. |
| Broccoli | Readily crosses with any Brassica oleracea species: Cauliflower, Cabbage, kale, brussels sprouts, kohlrabi, romanesco broccoli, kale, collard greens, broccoli |
| Brussels Sprouts | See: Broccoli |
| Carrot | Queen Anne’s Lace, and any subspecies of Daucus carota |
| Cabbage | See: Broccoli |
| Cauliflower | See: Broccoli |
| Corn | Sweet, flour, popcorn, flint, dent, and ornamental corns, teosinte |
| Cucumber | Will cross pollinated with parthenocarpic cucumber varieties. Please note: it is a commonly held belief that cucumbers will cross with squash and melons. This is false. |
| Eggplant | Self-fertilizing |
| Garlic | Self-fertilizing |
| Melons | Cucumis melo species will cross pollinate; honeydew, cantaloupe, canary melon, etc. Please note: they will not cross-pollinate with watermelons and cucumbers. |
| Onion | Note: onions will not cross-pollinate with leeks or chives. Bunching onions and bulb onions can cross-pollinate, although this is extremely rare. |
| Parsnip | Wild parsnip; It is a myth that carrots and parsnips will cross-pollinate |
| Pea | Self-pollinating; will not cross-pollinate with sweet peas. |
| Pepper | Hot peppers and sweet peppers will cross-pollinate |
| Potato | Propagated by tuber; cross-pollination isn’t an issue. (if you are propagating by seed, all varieties will cross with each other) |
| Radish | Wild radish; spring/summer, winter, and seedpod varieties will all cross-pollinate; daikon, wild mustard, wild turnip |
| Spinach | (more info coming) |
| Squash | Cucurbita maxima, C. mixta, C. pepo, and C. moschata will all cross-pollinate |
| Tomato | Self-fertilizing; potato-leaf varieties are slightly more prone to cross-pollination within varieties |
| Tomatillo | Require cross-pollination for fruit, plant one variety at a time to ensure seed purity. Will not cross-pollinate with tomatoes (this is a myth). |
| Turnip | Wild Turnip |
| Watermelon | Citron; will not cross pollinate with other melon varieties. |
