A really fun place to visit in Des Moines is the Greater Des Moines Botanical Center.
“Welcome to the Greater Des Moines Botanical Garden where exploring, explaining and celebrating the world of plants is our mission. Tropical and temperate gardens make us an oasis in the heart of downtown Des Moines. Whether you visit on your own or explore with a group, you will find the Botanical Garden a place where you can learn about fascinating plants, hone your gardening skills or immerse yourself in beautiful gardens.”
Here are some of the images I took at the Greater Des Moines Botanical Center a few years ago.
