There's a lot in that statement.
I guess other museums are too "dumb" to be able to grow a flower that smells like a dead body. Also, it seems odd that Milwaukee would boast that only they are so good at growing a flower that smells like a dead body.
Of course, I got skunk cabbage growing all through the wetlands behind my house. Don't ever step on skunk cabbage.

I’m told skunk cabbage is edible.
