Large sections are devoted to palms, herbs, annuals, unusuals, daylilies, natives, bog plants, and monumental plants. Spent about 4 hours there and took around 500 photos (many added to database here). Didn't have time to explore the arboretum side.
They also have large greenhouses and a nice gift shop.

Thanks, jmorth, for the photos; it's been several years since I've visited so it's nice to see that it is still as inviting. The last time was when they had their plant sale.
I was pretty impressed by their array and magnitude. What I experienced in the few hours there I'd rank near comparable to MOBOT (Missouri Botanical Garden in St Louis), at least for enjoyment and enlightenment (the outside part).
