Excerpt from Seed Saving: Introduction by the #SeedSavingExchange

"Know Your Plants

Know whether your parent plant is a hybrid or open-pollinated variety.

Open-pollinated varieties are like dog breeds; they will retain their distinct characteristics as long as they are pollinated (or “mated”) with the same “breed”/variety.

Hybrids, which are created by crossing plants of two different varieties, generally do not produce offspring with the same traits as the parent plant. Seeds saved from open-pollinated varieties, on the other hand, will produce plants identical to the parent.

Seed Savers Exchange offers only open-pollinated varieties through its online and print catalog and on The Exchange, its gardener-to-gardener seed swap.

So what are #OpenPollinated varieties, and what is their lifespan? Open-pollinated varieties are like dog breeds; they will retain their distinct characteristics as long as they are pollinated (or “mated”) with the same “breed”/variety.

This means, with a little care and planning, the seeds you produce will be true-to-type, keeping their distinct traits generation after generation as long as they do not cross-pollinate with other varieties of the same species.
Know your plants’ lifespans.

Open-pollinated varieties can be annual, biennial, and perennial.

Plants that flower, set seed, and die in a single growing season—like lettuce, tomatoes, and peppers—are called annuals.

Biennials, such as carrots and onions, don’t flower until their second growing season after they have gone through a cold period called vernalization.

Some long-lived plants, like apple trees and asparagus, are perennial, surviving and flowering for many years.

Know your plants’ specific name (genus and species).

The ‘Armenian’ cucumber, commonly sold as a cucumber, is actually a melon.

In biology, a genus is a taxonomy rank that groups together closely related species. For example, tomatoes (Solanum lycopersicum) are closely related to eggplants (Solanum melongena). In this case, Solanum is the genus that both tomatoes and eggplants belong to.

A species is a group of individuals that are able to reproduce together. All tomatoes belong to the species lycopersicum and are able to cross-pollinate (or transfer pollen between plants) with each other.

In the garden, most crops are different species from one another, but not always. There are several species of squash and two distinct species of kale—meaning some varieties of these crops are not able to cross-pollinate with each other.

On the other hand, Cucumis melo, commonly categorized as a melon, also contains some varieties that are sold as cucumbers (like ‘Armenian’) because fruits of the variety are unsweet and sometimes pickled.

Planting just one variety in a species will help ensure you save pure seed. But if you want to save seeds from more than one variety, knowing your plants’ scientific name will help you determine which ones may cross-pollinate. To save pure seed, you want to prevent cross-pollination between two different varieties in the same species.

The squash commonly grown in the Seed Savers Exchange gardens at #HeritageFarm, for example, could fall into one of three species: Cucurbita maxima, C. moschata, and C. pepo. These species won’t typically cross-pollinate.

On the other hand, Brassica oleracea includes broccoli, Brussels sprouts, cabbage, cauliflower, collards, kale, and kohlrabi, all plants you might think wouldn’t cross-pollinate but actually do. Read up on the cross-pollination habits of the plants you are saving seeds from to ensure you won’t run into issues."

Well rats! It looks like I'll have to plant my #beets in the #CommunityGarden, since I'm growing #Chard in the home garden. Oh well..

The #Beetroot Family

"Wind-pollinated members of the Beet Family have very light pollen and need up to 2 to 5 miles for safe distance isolation. Chard and beets are in the same species (Betula vulgaris) and must be isolated from each other or they will cross. Different Beet Family species will not cross-pollinate, so that one beet or chard, one quinoa (Chenopodium quinoa), one red (Chenopodium giganteum) and one white (C. alba) lamb's quarters, one orach (Atriplex hortensis) and one spinach (Spinacia oleracea) can all be grown together without danger of crossing.

"You can bag or cage varieties of the same species for isolation, but techniques vary depending on whether the species will self-pollinate or not. Quinoa and lamb's quarters are self-pollinating, so large paper bags can simply be fastened over individual seed heads for protection from cross-pollination. Since quinoa and lamb's quarters produce many small seed heads up and down their stems, mark the protected seed heads so that you can tell them from unprotected ones at harvest time.

"Beets, chard, orach and spinach will not pollinate themselves. These plants need to be caged or bagged in groups so that they can pollinate each other. At least 10 or more plants should be included in each cage or bag for adequate cross-pollination, and to help insure that there are twice as many female as male plants.

"Bags or cages need to be windproof to prevent intermingling of the very light pollens. Shake the plants together within their bags or cages regularly, to help the pollen mix move around inside the cage/bag for good pollination. "

Twinflower (Linnaea borealis) needs cross-pollination to produce seeds, but it often spreads by stolons to form clonal patches—meaning nearby plants may be genetically identical and unable to pollinate each other.

Two illustrations of the importance of cross-pollination in science.

“In any case, plant scientists were routinely thinking about the Krebs cycle in terms of growth, rather than ATP synthesis, long before most cancer biologists began to think that way. We should never forget that ideas in science often come from unexpected quarters. Focusing funding on research into human cancer would miss profound insights deriving from plant scientists.”

— Nick Lane, Transformer 📘

“The why, it turned out, was hiding in the quantum realm — a place geophysicists rarely tread. Likewise, most quantum physicists don't generally tackle the mysteries of geophysical fluids. But Marston was an exception.”

— Katie McCormick, How Quantum Physicists Explained Earth’s Oscillating Weather Patterns 📄
