Hi and welcome. It's really impossible to know what variety of brug you have. Just enjoy it and call it a pink/white NOID (no ID). A brug seed pod is hard to miss but with only one plant you won't be getting any seeds anyway. Even if you have more then one brug often hand pollination is necessary. Your second plant is indeed a datura (Devil's Trumpet). Not all varieties have spikey pods. In your zone they are treated as an annual and freely self seed. That's why you see them in your neighbor's yard every year. You can winter them over inside but it's much easier to start them from seed. They aren't easy to grow from cuttings like brugs are either. To collect seeds just wait until the pod starts to split then cut it off and put it in a paper bag. Once it's dried out you can remove the seeds and store them. If you leave the pods on the plant they'll split and the seeds go everywhere. Here's a pic of an almost ripe brug seed pod.

Hi , It is a datura and I know it's a white one if it survived a winter. There is only 1 sure shot datura that'll grow back over our winters. Up to zone 4 so I've read (with lots of mulching)

There are two white datura's. The innoxia and what your neighbor has is probably the Belle Blanche - the hardiest white. I have both whites this year. The innoxia have a very very light purple tinge around the very edge of the white flower just before it opens, the belle blanche has a very very light yellow tinge around it's outmost edge up until just before opening. The annoxia grow no taller than 3' (in my garden and from seed this year) but branch out much wider than the belle blanche, of who's branches tend to prefer up and out equally. My belle blanche have reached 4'+ when you include blooms, and all this in their first year from seeds, not from a big overwintered root.
Although the innoxia are very beautifully fragrant, the belle blanche are hardier (my innoxia severely wilted over one evening of a low 40F temp. The belle blanche are as nothing happened which is the same with my brugs up until this date (I live in a zone 6 pocket, but as all pockets go, can easily have a deadly evening of zone 5 low temps anytime through a winter). I'm sure I have my info accurate though, except what is only observation in my own garden (size) and a neighbours experience as I've seen it.

The belle blanche are from a root that grows thick in the ground and will come back next spring, though I'd through some mulch on. The annoxia, I doubt they will as there leaves already speak of a tenderness to cold, though I was told they would (an iffy would) for my zone. But the foliage looks horrible right now, which is about 1/2 of it's blooming season, so I'll stick to potting these or not at all. I'd rather have my pots used for the yellow or purple.

Mulching will only do the roots good!!
Karyn's picture shows you what all brug pods will look like, that's the one thing that pretty much looks the same on them all. The datura's are prickly ball things that I remove most of while they're in flower. Even 1 pod will be more than sufficient, there's dozens of seeds in 1. I don't find any datura easy to grow, more because of not knowing when they're going to germinate. Make sure you let your pod start drying out, though I did get mine from a fresh big fat green one a neighbor gave me of who's returns every year from the root. He says it get's to be a big invasive root, and we're up in a zone 6 pocket of 5.
I plan to move my roots around come next spring as the place where the innoxia are is going to be bare.

Happy Gardening - Sandy

Thanks Sandysseeds and Karyn for the info and pics.Last
month I did put in a brown bag to dry several pods
which look like your Brug pod pics. From your description
I may have Datura Belle Blanche. I bought it unamed from
a garden center in Martha's Vineyard, and they told me they
had been propagating it from the "mother" plant which grew
in the grown at the New York City Botanical Gardens and
returned each year. Thus far we have had some nights
in the low 50's and the leaves, Not blooming any more look
good. It has 5-6 large spiny seed pods which I am watching
for the right time to harvest and save/dry. I think I
may try to bury the Datura in the pot in the ground and heavily mulch over it. See if it survives the winter and
place in the grown directly next spring/in a sunny location
to see if I can establish it. I will also look for the
varieties you suggested/as named and try for next spring.
