Spring returns and so does the Cincinnati Art Museum’s annual “Art in Bloom” festivities. The weekend-long fusion of fine art and florals includes informative sessions on paper flowers, sugar flowers, and a presentation from the renowned floral artist Natasja Sadi, whose astonishing confections resembles the Baroque blooms of Golden Age still lifes. For the first time in the 20-plus years since “Art in Bloom” commenced, the floral artists have been selected by eminent jurors. —Lucy Horowitz
