By MaryAnn Fink, Life Exhibit curator of Pollinator Junction, pollinary park at the Museum of Transportation  She's a beauty! Her full name is Cephalanthus occidentalis, and yes I know, it's a mouthful. My friend Joe just calls her "Button" when we see her in the woods along the creek.  But, If that's too casual, you can call her Buttonbush (but write down her full two-word botanical name because someday,  you might need it). She's a local gal, a true Missouri native through and through. She likes it hot or, cold and humid and every combination of them but she's not real fond of extended dry period. (It's hard on her appearance and its tough on her roots as well and believe me, we all need our roots.) If you let her show her pretty leggy bark you get more than year round interest from the people lookers, you may also get oversize creamy white  flowers just in time for wedding pictures, graduation parties and all that is fun in June! Those sweet soft round globes are enjoyed
