Nicotiana
Sweet white flowers a mildly fragrant in the evening. It took two or three years before I finally got this to bloom. The seed is about the size of this period → . ←
Nicotiana alata is a species of “Nicotiana” tobacco. It is also called Jasmine Tobacco. The unwieldy 24″+ stems bloom freely producing gazillions of seed. Just now, there are dozens (maybe 100s) of the tiny plants coming up around every single square paver on my patio. After days and days of rain, the ity bitty seed have washed down between the pavers. and started to grow.
I added this to my worry list. It would be hard to pull the plants up without destroying the lush green moss. But I think the first frost will kill them off. The plant is only winter hardy to USDA Zones 10-11. I’m in 6A, SE Missouri.
The good news, it will be gone at first frost.
More night-blooming white flowers, Datura.
