Does it go from white pine back to currants?
Yes.
Great. I was hoping we could see alternating currants.

#22> it's contributing to the spread of related invasive trees that are taking over some urban green spaces and pastureland and encroaching on forests. I'll save you from the auto playing view port locker video.
A few more key points:
* At first the species being planted everywhere was considered sterile, but somehow cross-pollination with related varieties can make them produce viable fruit, then animals spread the seeds.
* The fruit is not edible to humans.
* Some varieties have nasty thorns on them, able to pop vehicle tires, and over time grow together into thickets.

#24blackcurrants were banned too (by federal united states gov) for some sort of complicated reason
Blackcurrant bans feel too heavy-handed to me. Currants are a wonderful berry, very easy to grow, and one of the easiest woody plants to propagate.

It's a host for white pine blister rust.
man that's complicated
Sure is! https://www.apsnet.org/edcenter/disandpath/fungalbasidio/pdl...
> The white pine blister rust pathogen is a typical heteroecious, macrocyclic rust that produces five distinct spore stages on two different hosts to complete its life cycle. The pycnial stage consists of pycniospores, or spermatia, which are haploid spores that fertilize compatible receptive hyphae. The two sexes are not distinguishable and are simply designated plus and minus. This is the stage where genetic recombination can occur that may lead to development of races of the rust. However, the nuclear cycle (i.e., dikaryogamy, diploidization, meiosis) of the blister rust fungus has not been fully determined, but is assumed to be the same as for other better known rust fungi such as Puccinia graminis. The aecial stage develops in host tissue occupied by pycnia the previous season (Figure 6). The fungus is perennial in the pine host and aeciospores are produced annually as long as the host tissues remain alive. Aeciospores are disseminated by wind over long distances, and Ribes spp. as far as 480 km (300 miles) from the nearest known white pines have been infected.

#28This is good news. In my area the only thing worse than Bradford pears are the Mimosas. It took me ~3 years of consistent work to clear off the Mimosas from our 1 acre lot in town. And I still have to spray or hand pull hundreds of the tiny ones each season because none of my neighbors have been as diligent.
What's wrong with Mimosas? They smell so nice in spring!

#29Was on HOA board where we had a road with quite a few of these trees. They were a fortune to prune because of the numerous small branches at higher reaches. As a board, we actually hoped they would come down in storms so we could replace with something more appropriate without the take down cost (and resident complaints). Another unqiue thing is during the summer it was not uncommon for a branch to suddenly explode -…
They also smell like someone took a rotting fish, dunked it in sewage and decided to roast it in the sun for a few days. They're everywhere where I live, and it's so bad.
These are the same trees known as Cum Trees, right?
My neighbors have a couple, I didn't know these before moving to the US, and the first time I smelled them was... something.

They are invasive, take hold and hard to eradicate/control, the flowers make a mess, and they are easily damaged in storms
