Simple answer is yet. Most likely if you google & find it stated that it your variety is OP, it should be the same from every source. BUT, some websites mis-name or mis-label seeds, some don’t list hybrids, sometimes there is a hybrid & an OP with the same name.

Unless you have very unusual varieties it shouldn’t be hard to reseach them. You can use the Folia database, compare it to Daves Garden, compared to a general google search. Or just post the ones that you are unsure of & see if the Folians know the variety (:

Both are excellent. The latter is a bit more accessible to beginners.

Hybrid seed can be saved, but there is no guarantee it will come true to type when planted.

“Heirloom” seed is open-pollinated, these are varieties that have stabilized over time so they come true to type. However, you need to also learn about cross-pollination. Some plants easily cross so seed may not come true to type. Squash, melons and pumpkins are all cross pollinators. If you have zucchini and pumpkins in the same garden, saved seed is quite likely to give you a zumpkin.

Most gardeners seem to agree that tomatoes and beans do not easily cross (within their species). You should be able to save seeds from both with surety. Beans are easy to save – you just let them dry on the vine and then crush them out of their pods. (Store in the freezer for at least two weeks after drying to kill any weevil larvae).

Tomato seeds need to be fermented and dried before storage. A quick google will reveal the method, it sounds intimidating but it’s quite easy.

Opinions on cross-pollination of pepper plants varies. Some say they cross readily, others disagree.

When species are known to cross, the only way to ensure pure seed in a small garden is to isolate the plants (using screens or blossom bags to keep out insects) and hand-pollinate.

My suggestion for you is to pick a few easy to save plants like beans and tomatoes for this year. Then read up on methods over fall and winter in prep for next season.

Have fun. And welcome to folia!
