I've had a relationship with Echium vulgare for decades now. I saw it along the highway in Michigan while traveling to Macinac island and those magnetic blue/pink flowers had me. I fumbled around for a few years trying to get seeds and have them germinate, but I finally did and then grew it for decades. ( in various places and sometimes purposefully torturing it!). And of course it seeded EVERYWHERE! I'm trying to attain a 100% native garden and it was troubling me to get rid of it with the bees loving it so much, but my native Canada wild rye saved me the trouble and completely eradicated the mother and all the babies. I love watching native plants beat the crap out of these alien, noxious, invasives! The mulleins and teasle are taking a severe beating too this year with all the rain. VB is like sticky/prickly right? not thorny/prickly? ( how quickly we forget!) lol. :)

Not toxic, as far as I can see, but the seed capsules have a kind of barbs, and they cling to clothing and the fur of animals. Skirts or pant legs can be full of them, and you have to remove them individually. This is the one weed I try to eradicate from my garden every year, but every time some little plants escape me, and its seeds hitch a ride on my pants. Or the fur of my poor long haired cat.

i know your new.. and i hope you come back often .. and just as a hint for future posts.. pix in front of a bright window are not the best ... though in this case.. it didnt matter ... pot them up asap ... in fact ... i dont know why those long pieces were rooted .. you can probably cut that long stalk into about 8 pieces and root them up ... very fast.. in media.. check out the link below ... and note .. the best info is found using the proper botanical name... rather than the name of some dive bar in key largo.. lol .. the lucky bamboo... crikey ... lol in general.. if you break off a large piece.. its very hard to root big pieces.. so you research to find out how small you need to go.. to make it easier for the plant to root ... not many plants can move enough water up a very long stem to save the leaves above.. if it has no roots ... this bamboo is probably one of the few exceptions ... ken https://duckduckgo.com/?q=Dracaena+braunii+propagation&t=ffcm&iax=videos&ia=videos

There is a part on the seed that ants eat and then they carry the seed to new locations. I have a blood root growing in one of my hosta beds for 20 years that has multiplied into a big clump but last year I noticed seedlings popping up 7 to 10 feet away from the momma. I let them grow in their spot between stepping stones for the last year and have moved them into a permanent location in the last month. I put a double flowering bloodroot in my front hosta bed last year and it had one leaf but no flowers this year. It is still alive (yay) so hopefully if will be happy and multiply.
