Tiger Tots greenhouse tour on a very hot day

Kate Chaumont (my new greenhouse employee extraordinaire) conducted a tour in the Tucker greenhouse today for two groups of students from Tiger Tots Child Development/Early Learning Center.  Since it was going to be a scorcher of a day today, Kate made homemade fans for the students out of paper ‘leaves’, she gave them all their own little succulent plants from her home stash, she placed chocolate bars on the cacao tree, a bottle of vanilla near the vanilla orchid, plastic dinosaurs near the cycads and ferns, and plastic frogs and turtles throughout the greenhouses.  She even brought in her gecko from home named Bootstrap.  She let all the students pet him.  This was a greenhouse tour the students will never ever forget.


Dr. David Dunn…Because of him, we have the Tucker Greenhouse.

Dr. Dunn taught Plant Taxonomy for years at MU.  He was largely responsible for the design of the Tucker greenhouse.  He collected the majority of the plants now growing in the greenhouse too.  I recently visited with his daughter who shared stories with me of her dad, ‘Doc’, and of plant collecting trips she went on with him and his graduate students all over Mexico & Central America.  This photo of him was taken on one of those many trips.

My coworker Melody Kroll and I recently went to MU Archives to look at the huge collection housed there of Dr. Dunn’s research, etc.  In a file labeled ‘Plant Collection trips ’69-’71’, I found his hand-drawn phylogenetic trees of various plant families. See two of the best below.

Also, we discovered lots and lots of letters people had sent to him asking for his help in identifying plants.  He was quite well known for his plant identification skills.  He would take the time to ID all the plants people sent to him, and he’d write back a very personal, detailed reply about each plant. There were hundreds of these.  One really stuck out for me.

A woman in New York submitted some leaves to Ralston Purina (the pet food corporation) asking them to ID a plant that her dog kept eating.  She thought that since it didn’t make her dog sick, maybe they should use this plant in their pet food recipe. Ralston Purina sent her letter to Dr. Dunn, and sent the woman a letter telling her that they’d submitted her leaf sample and her letter to a renowned Botanist at the University of MO who was the expert in identifying plants.

Dr. Dunn’s daughter also shared with me that her dad was a frequent guest of a local television show called ‘Of Interest to Women’.  This was a gardening show about spring planting, preparing gardens for planting in fall, and how and when to plant a certain plant.

More to come on Dr. Dunn and his amazing career at MU.


Cacti donations made to the Tucker greenhouse!


Echinocactus grusonii-Cactaceae (Barrel cactus)

This Saguaro is 40 years old. It might send out its first branch in another 20 years.


cactus 2

This Carnegie gigantic is ten years old Cactaceae (Saguaro cactus)

These three cacti were generously donated to the Tucker greenhouse ‘Desert room’ by Dr. Jeanne Mihail from the Plant Science Dept. at MU.  Dr. Mihail grew the smaller Saguaro from a seed!  Dr. Mihail is a mycologist and teaches ‘Biology of Fungi’.
