Marilyn good form in the branching, so that the blooms aren't all smooshed together, is known as candelabra branching. And you can see why from Tom's photo. It allows each bloom to attain its beautiful form if it's capable of it. Bloom sequence in the buds also helps that. For example, in Tom's photo, if you look at that top bloom, you'll see a bud coming up under it, starting to crowd it a bit. But if the timing is good, that top bloom will be spent and deadheaded by the time the bud underneath opens.
