Okra vertical garden ready to flower!

See my Okra vertical garden ready to flower! Close look at the plants will tell you that all of them have flower buds. I expect them to grow up in a few days and start flowering. Okra flowers are quite beautiful and resemble shoe flower. Can you guess why? Of course, it is because both plants belong to the same plant family. While shoe flower is usually red, Okra flowers are yellow. There is another plant in the wild, with plenty of thorns which has almost the same colour and appearance of flowers. Once these plants start flowering, I expect a good yield of Okra fruits soon. Somehow, Okra has been the only vegetable to give consistent yields here. They also get affected by pests some time later, like all other vegetable plants here.
