Q: Here is a picture of a new plant sprouting up in my yard. Is it a weed or something nice? Will it grow tall? Leave it or yank it? Thanks.
A:Â It is called tree tobacco (Nicotiana glauca). Tree tobacco is a slender, erect, straggling shrub or small tree growing 6 to 20 feet tall. Tree tobacco produces sprays of nodding, tubular bright yellow flowers and is a prolific seed producer. Opinions differ on its status as a weed or ornamental. It is a bit stinky and the plant parts are toxic to animals like some other plants in the Solanaceae plant family so you should keep children and pets away from it. I have a friend that likes the yellow flowers they produce and keeps it around for that reason.
