Somebody can help me with the ID of this very annoying weed?
Location: Thailand
Please help!
Looks like an Ipomoea, Morning Glory, a relative of Sweet Potato. The weed ones can be very difficult to get rid of.
Yes Ipomoea.
Can you show a flower?
The flower will tell the Genus.
I had a closer look and now I'd say it's Operculina aequisepala, or O. turpethum. The flowers are white, typical Convolvulaceae shape, but smaller than some of the Ipomoea.
No worries. They do get quite weedy. If you can water them durng the dry season they rot.
