We have an older vine that went downhill and now is coming back with lots of new growth. We noticed on the new growth a strange type of fungus which is attracting ants. I provide a picture of the growth which we have been cutting off fearing it is harmful to the plant.
It likely is a type of mushroom, which would be harmless to the plant. However, I think I would cut off that part of the stem just to be on the safe side.
The bean shape is about 4 inches long and very hard
Sorry. I have to remove the image url. We have to try and stick with .edu sites when it comes to photos.
A seed pod? See this picture:
I bought a trumpet vine late summer of 2021 so I never got it planted. I am in WI, by the way. It wintered inside in a southern exposure window. It grew like crazy and I had to keep cutting it back. This spring I planted it outside. It is a beautiful, healthy dark green plant that never grew. I mean NEVER got any bigger. It us planted in an area that is partial sun. I can't decide whether I should duf it up and bring it in for the winter or let it winter outside and see what hapoens.
It is taking a while for its roots to get established, rather than putting on top growth. Leave it for the winter, then in spring, it should take off. If it doesn't, have your soil tested; there may be a problem there. Trumpet vine is not particular about soils and does not need fertilizer.
It is hardy to zone 4, so it should do Ok in winter. It should die back but return in spring. It suckers underground, so be sure it is in a place where you can mow off the suckers or where it won't overtake other plants.
I bought a Flaming trumpet creeper almost a year ago which has recently had a couple of blooms. I planted it directly into the soil. It was shown in the website that it has brigh orange coloured flowers but my blooms have been somewhat of a pale yellow almost white type of colour. I have checked online and there doesn't seem to be any colour variation of this creeper. So why is the colour so different?
There are certain cultivars that match this color and structure. Campsis radicans 'Flava' is the most common that comes to mind. It is very possible that it had dropped seeds, already, and they were a cross with the yellow lineage. This can show through.
Less common is reversion. Reverting back to one genetic set or another is possible, but this is pretty rare.
You can prune it in spring. The vine may not be mature enough to bloom yet. They tend to be slow starters but once they take off they can be problematic, suckering underground. Make sure it is getting full sun. These articles should help:
