Mobot is a world class botanical garden, surprised you've not been there.
I'm would suggest going to their website if planning a trip to be sure said plant is on display when you go. I think they may periodically change the venue in the building where I got that picture, I think it's called the Linnean House. I took that picture in February (2013).

If you make it to St Louis, another enjoyable place to visit (related to plants) run by Mobot is the Butterfly House in a western suburb named Chesterfield.

Hope you and your wife make it there, the place is guaranteed to impress.
