I planted a variety of beans from seed this year and the Purple podded pole bean has continually proven merit in flavor, productivity and beauty.
I purchased these beans from Grow Organics http://www.groworganic.com/pvfs-bean-pole-purple-pod.html
Back in January for planting here in
Long Beach, California. I waited for the soil to heat up a bit in my raised planting beds(68 degrees). I provided a trellis for these vigorous growers and placed them in the ground at the depth of 4x's their narrowest width. Lightly watered until sprouted, more water when blooming then kept moist while fruit is forming.
Great eaten raw when under 3", delicious sautéed with olive oil butter and garlic!
This bean will be a standard in my garden!
