I have a second year major wheeler which I have on a 6 ft trellis which is supported against a yard light. I now wish I had gotten an 8ft trellis as it as grown to the top of the yard light which is taller than my trellis. Maybe you could use a large pot of some kind and have your husband build a support around the pot in the shape of an upside down U. Just a thought.

the link should give you a good idea of color ... https://www.google.com/search?q=Lonicera+sempervirens+%27Major+Wheeler%27&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj3hovK7MrLAhWmmoMKHdedD6EQ_AUICCgC&biw=932&bih=743&dpr=0.9 understand.. deep colors like this... will look washed out at mid day.. rather than morning or evening .... its all about how wide open your eyeballs are.. as compared to squinting ... akin to how peeps had to manipulate aperture back with old SLR cameras ... coral bells are rather early bloomers .. honeysuckle.. mid to late summer ..to my mind ... matching color in two different seasons isnt worth it ... you seem to be going at this.. more like an interior designer.. rather than a gardener .. and all the power to you on that ...just an observation ... i just never thought about flower color in making choices .. size.. form.. texture.. bloom time ... would all come before flower color ... a way out suggestion .. an earlier blooming clematis.. grown together ... might be interesting ... and if a different color.. you have two colors.. in two different seasons ... i have a vining Honeysuckle ... it goes ten feet down the fence.. each way of the spot its planted ... and its 3 to 5 feet laterally off the fence ....that make it a 20 foot plant ... how big is your trellis??? .. will it support the plant in the future??? and in the alternative... how would you train it to size.. can it be pruned severely .... annually ... i dont know.. since i have the fence ... GOOD LUCK!!!! ken

I second floral's comment. If you cut it back, you remove some of the leaves which produce the energy the plants uses to grow, so you will be slowing down its ability to settle in, put out roots, and start filling the trellis. If you feel it still needs shaping by the end of the season, I would do that over the winter some time, though when to do it in your zone, I don't know exactly.

Most woody vines like honeysuckle are more like trees and shrubs with a single trunk-like base rather than multistemmed perennials and are not divided. ==>> in other words.. they cant be split ... sometimes there might be two plant in a pot.. and they could be SEPARATED ... but not split..nor divided .... in this case.. words mean things ... we'll get you up to speed on the lingo ... dont worry about that ... my usual caveat is diversity ... in case something happens to one.. you dont lose all 4 at once.. having to start over .... and also ... too much of anything is just boring ... find something that blooms at a different time.. otherwise.. you will have great bloom for a week or two .. and then boring green for the rest of the year ... and dont get hooked on the marketing nonsense of this is the longest blooming whatever ... think about that.. that doesnt mean anything.. it surely doesnt mean all summer or some such ... find a fall blooming vine.. a early spring blooming vine.. and this mid summer vine.. spread your flowering season.. like you should do in the rest of the garden ... [avoid autumn sweet clematis though].... ken
