Birdseed is a mixture of different seeds, so what it grows into depends on the specific seeds in the mix.

Here are some common birdseed ingredients and what they grow into:

* Sunflower seeds: Sunflowers

* Nyjer (thistle) seeds: Thistle plants (not the kind that grows prickly weeds!)

* Milo: Sorghum, a grain used for livestock feed and sometimes for human consumption

* Safflower seeds: Safflower plants, which produce edible oil and yellow dye

* Wheat: Wheat plants, which produce grain for bread and other foods

* Oats: Oat plants, which produce grains for oatmeal, breakfast cereal, and animal feed

* Corn: Corn plants, which produce ears of corn

* Cracked corn: Corn plants

If you're wondering what a specific birdseed mix will grow into, check the packaging for a list of ingredients. You can then research those seeds online or in a gardening book to see what kind of plants they will produce.
