Well, for starters, they are kinda pretty, in a "corn stalk" sort of way
But beyond that, I clean them off and use them as trellis or stake materials. They are great for staking up bolted plants so I can collect seeds. I have them as part of my make shift pea and bean trellis. I also can use them to secure netting in places. They are very strong, they likely would work for tomatoes, though maybe use more than one there.
They are also great for backyard fires.
