I do stake all my tall snapdragons once when the first flower spike is forming. The first spike is always the tallest/largest because it's getting a high proportion of the plants energy. The plants then branch out better so you have more blooms, but they're a bit shorter because the plants energy is divided among more flowers. No additional staking is done or needed from this point on.

The "Plumblossom" Snaps are the tallest ones I've grown so far. The "Rocket Series" are usually around 3 feet and the "Plumblossom" is typically 3 1/2 - 4 feet. Here's a photo of some "Rocket White" Snapdragons this morning.
