Botanical Experiment #37B was a bouquet of flowers created by Ludwig von Drake.
Description[]
Botanical Experiment #37B was a bouquet of white flowers rigorously identical to the flowers usually worn in her hair or on her hat by Matilda McDuck. Ludwig von Drake created this bouquet during his attempts to woo Matilda, with whom he had fallen in love. Matilda was delighted when Ludwig presented the flowers to her underneath a “sweetheart tree” where they'd carved up their initials like schoolchildren.
