: Are sunflower seeds poisonous to other plants?
sunflowers do have toxins that inhibit plant growth but i always thought it was the plant, not the seed. there are plenty of seeds that do release toxins, mainly to inhibit other seeds from germinating, so it is possible. if you want to research it on the web look under allelopathic affects of sunflower seeds. good luck!
