Is there a combo ticket you can buy for both the butterfly house and gardan?

There is a separate butterfly house that is not at the botanical gardens. You can purchase a combo ticket for both at the botanical gardens. They are both awesome. Well worth a visit

The butterfly house is in a different park in Chesterfield.....is that what you mean?

That I'm not sure of that, they have a climatron there that is included , I don't believe that they have a butterfly house by it self
