That really is gorgeous, Sandy. I've had two cattle panel trellises up in two tunnels side by side--this will be the third season. My problem is the cucumber beetles don't usually give the plants enough time to grow and cover the arches the way I want them to before they die of wilt! My trombettas are the only ones that never fail to climb all the way up and then down the other side; I didn't realize they were moschatas until this year.
That one's coming from a plant growing from the other side of the trellis. The vines you can see are Malabar spinach and beans. I also like growing tomatoes up the sides.
... and the nasturtiums loved the tomatoes last year. So sweet! But tomato foliage isn't as impressive as cucurbit foliage. What you got was the effect I really want! So I'm planting only moschatas and a few watermelons this year and no cucumbers or muskmelons. I hope my arches will be as spectacular as yours this year!
Also, I did grow a gourd plant last year and got a couple of small ones. Too much shade where I planted them. I put them in the copper wire produce keeper hanging from the ceiling in the kitchen and now they're dry as husks. All the air circulation may have helped keep them from rotting.
