An Experiment With Heirloom Bean Seeds
Oct 25th, 2009 by tommy
This year my family planted several varieties of heirloom bean seeds we purchased from Seed Savers Exchange. We tried Painted Pony, Calypso, Speckled Cranberry, and Brockton. We planted the seeds directly into the garden in early June after our long, wet spring. Since we only purchased one packet of each, we were able to seed a 10 foot row of each variety. As with a lot of heirloom vegetables, the germination percentage was anywhere between 70-90%.

Heirloom Beans: Painted Pony, Speckled Cranberry, and Calypso
After the beans were up for about two to three weeks we had a grasshopper invasion. About 50% of our seedlings were eaten. And if that wasn’t bad enough we had a loss of another 10-20% to disease within the next month. At this time we were getting pretty discouraged.
In mid September, we were able to harvest a few dry pods from our Calypso plants (all three of them!). Just a few days ago we harvested the last of our dry pods. The Brockton variety, though our toughest and most prolific, did not have enough time before the frost set in to mature any seeds. And, even though we did not have many Calypso plants, they ripened the earliest as I mentioned above. We harvested just two pods of Speckled Cranberry, a late ripening type. The Painted Pony plants, however, performed the best in terms of the amount of dry bean seed we were able to collect.
I should mention that all of the varieties produced fresh green beans in abundance. But, since we were interested in collecting seeds only, I do not have an edible flavor comparison to share.
In subsequent years we will probably plant twice as many as we want to grow to mature plants. In addition, we will focus on shorter season varieties when we want to harvest dry seeds for saving.
Overall our experiment with heirloom bean seeds was fun. The best part was watching the kids open the dried pods to find the brightly colored beans inside….the simple joys of gardening at their best!
