But a newer one is? I've had the non-blooming one for a couple months. It's grown rapidly and is half way up the trellis, but no blooms or even buds. We bought another one for the other side of the arch trellis, and it has blooms on it already, while the other one doesn't even have buds. What gives?

Do they get the same exposure to sunlight on both sides of your trellis?

I checked my summer sunlight inventory pics, I'm going to say the older one gets more, since the newer one is in the shadow of the house the first part of the day, although the older one has been moved to the end of the planter, and the planter moved a bit. Short story is it was in the shadow of the shed early on.

I also googled around and read that they often need to mature a few years before they bloom. They're both on the side of the house that gets the most sunlight. Another factor is a worker at the nursery picked out the newer one for us and said it was the healthiest one of the picks. I didn't ask for help picking the older one, just read the tag and said "cool" and put it in the cart (my wife wasn't with me either for the first one, she's a stickler for asking questions).

I had a trumpet vine for several seasons and it never bloomed for me. I had it on the east side of a porch with morning sun, then moved it to a sunnier location on a fence with more sun exposure. Finally just dug it out, figured for whatever reason it wasn't going to bloom for me. Mine also got good growth, just no blooms. Maybe it doesn't like our climate for some reason?

Time will tell, way too early to give up on mine. Here's a couple of links I found.

Maybe give it a little bloom booster fert? A bit late in the summer but it might bloom yet if it's put on enough new growth.

Like Wisteria, Trumpet Vines can take years to start blooming and there is no way to hurry it up. I've had one at my old house going on 6 years and it was a cutting from a blooming branch and it has yet to bloom - will probably bloom like crazy next year. If you're desperate for blooms of some sort, plant a MG next to it.

What's an MG? Marigold? Not desperate, it can wait if that's what they do.

That's what the lady at the nursery said too, so I got some Dr. Earth BB fert, but haven't used it yet. One of the links I posted says fert will actually hinder blooms (something about nitrogen in the dirt), but maybe the Dr. Earth stuff is different?

MG = Morning Glory. It will grow fast and give you blooms until the trumpet vine kicks in. I had a trumpet vine that was several years old before it bloomed also.

Jay is right - Morning Glory. Hummingbirds love them. Send me a Tree Mail with your address and I'll be happy to send you some seeds for next year .. it's too late now to start them.

They take several years to bloom. I would advise you to get rid of the trumpet vine while it is still smaller. They will spread all over from their roots and are almost extremely difficult to get rid of as they will sprout all over the place. I speak from experience someone gave me a start, which grew and took it's sweet time to bloom. The vine looked good for a number of years until it started sprouting all over the garden. I got rid of the main vine a number of years ago and still it sprouts in the garden from the roots that traveled. I would never ever had planted one if I had been aware of what a thug it is, now years later I am still trying to get rid of those sprouts that pop up overnite and grow fast.

I think whether a plant is a thug or not is largely dependent on your zone/climate. I've heard that trumpet vine CAN be invasive, but I did not find it so. I had one in the same spot for several years and it increased normally but not aggressively. I moved it to another spot and only had to pull a couple stray sprouts the next year from the old spot. I pulled it out completely from the second location, and haven't seen it since. Definitely not a plant I would consider a pest or invasive, just a non-bloomer for me.

Thanks for sharing your experience with them, sorry it was such a negative one. These are in a container if that's any advantage to controlling them. Time will tell, but for now I'll keep them. However had I known they take that long to bloom I would have went with the MGs instead. As far as unwanted things sprouting up, I have lots of that anyway in the form of various weeds that are impossible to keep up with.
