May is the month of peak flowering in the southern Willamette Valley. Riparian galleries, oak woodlands and grassy hillsides are awash in a glorious array of nature’s prize beauties. This season is celebrated every year at the Mount Pisgah Arboretum with a spectacular wildflower show. The Wildflower Festival is May 17, as always the first Sunday after Mother’s Day. Music, food and crafts are all available. As part of the festival activities, I will lead a nature walk and give a talk about fringecup, Tellima grandiflora, the Flower of the Year.
