Q.Odd “bloom” On Pole Beans & No Blooms

Zone 37172 | nepcpp added on August 22, 2020 | Answered

I have been raising pole blue lake for 20 & have never seen this before. The only “bloom” is spiky looking. The “seed” in the middle of the bloom is a tiny whitish yellow hard ball. I took pictures – they’re attached. The plants are lush & green – have never bloomed. I haven’t used my soil tester, but I’m sure the lack of blooms is because of either too much or not enough of something. The odd bloom is what’s got me puzzled. Anybody ever see an odd bloom?
