I bought 2 blueberry bushes mid spring and planted them in my yard. They now have this new growth I have never seen on any of my other blueberry plants. The new growth limbs are long and thin with lots of small branches. The ends of the branches have pod like things on them that have purple and white flowers on them. But the pods are breaking open and they have fluffy white seeds in them, that look like the seeds of a dandelion.( the kind that blow away with the wind). What is going on with these plants? I'm completely baffled. (Yes I know I need more nitrates also lol)! I'm trying one more time with new pics.. They all come off of one main trunk. The limbs actually go from bb bush to this thing which does look like the plant someone mentioned below in the comments. So idk.. enter image description here
You have two different plants in the same spot here. One is your blueberry (thick branches with round leaves and berries), the other is a weed that happens to grow there as well (everything you described as “strange growth“). Those are not new branches of blueberry and you can simply pull them out. In fact, I recommend you do so soon, it’s outcompeting your blueberry with regards to water, light and nutrients.
For a precise identification we would ideally have better photos, preferably close-ups, but from what you gave us, I would say it’s probably smallflower hairy willowherb, Epilobium parviflorum. Widely distributed in Europe, it’s a neophyte in the US (which already means you should pull it out). If you let it be, you can expect to see more of them next season, as the “white fluffy stuff“ are seeds which get distributed by the wind - just like the dandelions you compared it to.
We definitely need better photos. Is that the 'blueberry' in the center of the photo? What variety of blueberry? The plant in the center is the weird growth you are talking about? Along with the loopy 'aerial roots'?
I think you have an Epiphyte. A non parasitic 'air' plant. You picked it up at the nursery with your blueberry shrubs. Until you send better pictures we don't know which epiphyte. I would call the nursery or store you purchased your shrubs and ask them if they also sell air plants. Perhaps one was on a tree above the pots of blueberries? Or a seed blew into the soil of your potted shrubs?
Very interesting. This could be Spanish Moss.
