    Snapdragons are referred to as half-hardy annuals; they will survive if winter is mild or if insulated by snow. I cut mine back to where it is green. The roots of plants that didn't make it can be left to compost. Those I snip off at ground level. Hybrids will slowly change height and color as they don't come back true from seed. I now have some 6" yellow snaps, 12" pink and taller red and several with mixed colors - all from the same original red plants. I have an informal garden and this works well for me.

    Snapdragon seeds are extremely small and black. You've identified the seed head. Wait until it is dark brown to black before harvesting seed. Often you'll see the seed pod start to open. This is when the seed is ready. If you are storing seed indoors over the winter, make sure it is completely dry then put it in a glass jar in the refrig or basement - anywhere around 40 degrees F. In zone 5, you can also strew the seed outdoors where you want it to grow next spring. Do not cover the seeds with soil. You will get blooms earlier if you start the seeds indoors in late winter. Here is an article that explains growing snapdragon from seed. https://www.gardeningknowhow.com/ornamental/flowers/snapdragon/growing-snapdragon-seeds.htm

    These seem to be the same article and they both say to plant in full sun.

    Full to part sun is correct for snapdragons.

    Sure, you can pull off the brown, spent buds! If you wanted to wait until the entire flower stalk dies, you can prune it all at once and possibly harvest seeds.

    You can deadhead them below the first flower on the spike. Later in the summer if the blooming slows, cut it back by a third to one-half to promote new growth.

    Yes, you can trim them back to promote more blooms. The newer cultivars don't seem to need much trimming. They keep blooming no matter what. The perennial snapdragon, Spanish snapdragon, blooms all summer.
