There's not a lot of info out there regarding this bean, attesting to it's increasing rarity. Fortunately, it has been well documented right here on Green Country Seed Savers. It can be reviewed here.
After reading about the trials performed in the past, I discussed this bean with Glen. He was kind enough to send some Oaxacan Cream pole bean seeds my way this Spring. We thought we'd see how it does at 39 degrees N here in the Shenandoah Valley. We have concerns about the ability to produce and save seed, but decided to give it a try anyway.
Seeds were planted on 6/03. Inoculant was not used, as beans have been grown in this soil in prior years. Germination was excellent – 11 out of 12 seeds, or 92%. (Note: I'm actually growing two trellises of Oaxacan Cream for seed saving purposes, but for this log I will only be documenting this one trellis as a representative sample.) Here's what the seeds looked like.
7/06 – Seeds were planted 6 inches apart. This is 30 days after planting.
7/10 - Plants are reluctant climbers, but with a little help training, they get the idea.
7/16 – Hard to describe, but these vines seem to be “clingy”. Kinda like if they wrap around your shirtsleeve, you have to “peel” them back off. Hope that makes sense.
8/07 - Oaxcan Cream continues to grow, but is being attacked by the Mexican Bean Beetle. Damage is fairly significant. I need to spray, but it has rained every day for over a week. Maybe a break in a few days. Still no sign of flowers.
Plants have reached the top of the trellis and begun the vine dance.
