,,,and vine(s)

the top photo is one of the trellises in the garden and they are filling in nicely with a tangle of pole bean vines ( no blooms yet )...the vine in the bottom photo has latched onto a jerusalem artichoke in the next bed over...despite their colloquial name, sunchokes throw a lot of shade as you can see by the darker greens in the photo...i don't doubt the vine will find it's way to the jerusalem artichoke canopy and the sun but i am curious to see how man leaves ( if any ) it successfully deploys in the shade...time will tell, no?
