Why do perennials get taller than they're supposed to?

I have some perennials which have gotten taller than the tag states they should get, and I wonder why. An example is "Iron Butterfly" ironweed -- supposed to get 24-36" tall, it's about 5 foot this year. Its in full sun, so isn't stretching for more light. Anyway, just wondering.
