non-blooming clematis identification #759374

Asked June 30, 2021, 7:39 PM EDT

This clematis was started from a seed pod similar to a large green bean. The original plant only bloomed once. This plant is at least 5 years old and appears to like where it is planted. The one bean pod actually produced three plants. None have ever bloomed. It gets morning sun up to approximately noon. I have tried looking online at leaves of clematis and have been unsuccessful in my attempts. By any chance, can any one identify it. I've read that too much fertilizer produces more of the green vining and no blooms. It is growing behind a garage with irises and hostas which all do well. Thank you.

Good early morning. I received your question. I do not believe you are dealing with a clematis. Perhaps that is why you are having some issues with it? Clematis don’t generally produce seed pods. I think that the picture you sent us is an American Wisteria (Wisteria frutescenes). What, exactly, do you want to do with this plant?  I will be glad to help you.

Interesting!!  The mother plant (labeled clematis) was purchased as a thank you gift.  I was then given a seed pod.  No idea they grew well in Minnesota.   Would it help to try transplant them because wisteria is going to get much bigger and need more room like a trumpeter vine, right?  Will they transplant well?  I have a big yard and could move them someplace else.  Depending on sun issues.  Back yard is sunny and front is mostly shade.  I had for years two  beautiful climbing hydrageas over a front door arch but a couple of years ago a bad winter caused severe die back and one side of the arch never came back and the other has been struggling to do much since.  I kept the thick vines on the arch for decor.  They were so rustic looking but last year they were so dry, they broke off and now the arch is vacant.  That faces west/north but is a lot of shade.  Two could go on either side of the arch.  Or if more sun is needed, I would have a spot for one opposite my trumpter vinein the back yard.  I read that they bloom on woody branches.  They really don't have woody branches..just keep growing vines that have no place to go at the back of the garage.   The gifted mother plant bloomed right away after planting....wondering how it had any woody branches????  So I guess, I just need some suggestions since I have something I wasn't planning on which now makes this an interesting mystery and challenge.

Thanks for the response.  Before we go further down this path, I want to be sure that I was correct in my initial assessment.  Could you send us another two or three pictures of this plant, taken either at a distance or close up?  Be sure that you distinguish between a plant from the seed pod and the plant you were given. What exactly are we looking at?  The plant you were given or the plant from the seed pod? It almost sounds as if we are dealing with tow different plants.  Once I am fully confident in my plant identification, I will be able to answer your questions.  In this regard, you mentioned that the "mother plant", possibly clematis or something else bloomed.  The best way to get a positive ID is to have a picture of these blooms.  Is that possible?  And just so I understand, the seed pod you received may or may not have come from a clematis? Correct?  And the picture you send me came from this seed pod?  Correct.

I apologize for all my questions.  However in order to provide you with the bast advice that I can, I need this information.  Sorry for whatever inconvenience that this might impose.

Sure - no problem in trying to answer all your questions.  This thing has been a mystery to me for a long time and having someone to share in it, is kind of fun(ny).  

The original plant was a gift 10 years ago  to a friend and the label indicated it was a clematis.  The first or second year, it bloomed for the friend and she gave me a seed pod.  I remember it looking like a straight bean pod, like a brown green bean.  I planted them in pots and got 5 little plants.  They were transplanted behind my garage which faces east.  This week I contacted the friend because I wanted to question her on how it was doing.  She said it has never bloomed again and I haven't seen it since it grew straight up the double-split entry house.  There are no pictures of the flower or bean pod.    Since our first communication, I googled wisteria bean pods and have seen they are not straight.....more a ugly tear drop shape:)

Three of my plants continued growing though not very well for about 5 years.   They have always come back but stayed small.  The lower 3 feet have turned "woody".    Then the last two years they have just started to vine out and have grown taller than our garage and each plant has become tangled into itself which I'd like to correct.

Here are pictures of all three.  I'm agreeing with your identification from what I've been able to see online.  I haven't been able to get back to the friend and have pictures sent of her plant.  Probably gone due to the July 4th weekend.  

As you can see, all the plants look the same.  Just a couple woody stems that after about 3 feet they then are green vines.    I did notice something different on one of the joint of the leaves, a few bumps-wondering if this is how a blossom would present itself.

I think I've answered everything. 

Once we figure this out, my question initially was concerning blooming.  I'd like to know how to fertilize and then also as for the lighting element as to whether it could handle being moved to a western shadier location on my now vacant arch or in a much sunnier location but it is sandier soil there.  The arches sure would allow it to climb better than being stuck under the garage overhang.  Would transplanting after all these years be an issue in itself?  

If you have any other questions, feel free to email again.  I appreciate the time and interest and look forward to your responses.

Thank you.  Carol

Thanks for sending the pictures. All of the plants shown in what you just sent me, as well as the original picture, are American Wisteria (Wisteria frutescenes). Wisteria needs to have phosphate in the soil in order to bloom. A good source of phosphate is bone meal. It releases phosphate over a period of time. Transplanting wisteria can either be done in the fall (first part of September) or early spring. I think that the best success would be a fall transplant. After transplanting keep the plant very well-watered. Here are some other sites on wisteria:
