They're flowering, so you'll get peas. What the heat does is keep them from flowering.

One little thing you could do would be to cover that black side of the planter with white or beige. It will reflect light rather than warmth. The peas will bloom and bear for three weeks or more, and their color right now looks great. Can you get to the back side for harvesting?

Good idea thanks! Yes I I could to the back side. Not easily but I'm small enough. That cart has wheels wont won't be and me to move it with peas growing into chicken wire
