The leaves, stems, and seeds are allelopathic, which means that they will release some toxin or toxins (not harmful to humans and pets in small doses) that prevent or slow the growth of other plants in the effected area. Sunflowers excrete a toxin that prevents seeds from sprouting and seedlings from growing. The toxin is biodegradable it takes about 3 months for the toxin to completely dissipate. This being said however as long as the sunflowers are not right next your other garden plants they will most likely be fine.
