I'm new to this site. I have recently moved home and have a plant/ weed growing very rapidly!! Does anyone have any idea what it is?? Thank you!!
Where are you located?
Has the plant been sprayed with a weedkiller recently?
It is a Swiss chard plant which has bolted and gone to seed. It will have a honey like fragrance. If you can bear to keep it it will probably self sow. Mine do.
