Not the Garden of Eden but better, actually, because no incorporeal NIMBY kicks you out for having a delicious healthy snack: The Vortex Theatre celebrates their 15th year as a nationally certified butterfly sanctuary. For all those years they’ve “actively cultivated butterfly vines, fed the caterpillars, and watched them emerge from their chrysalises,” resulting in a flooring 40 different species who’ve passed through the artsy Manor spot. A full day of festivities awaits, from live music by Roland & the Roots Riddim and Ogo and the Erph Tones; songs & scenes from upcoming Vortex production MotherTree; hands-on opportunities like a Tiny Tails petting zoo, butterfly inspired arts & crafts, and the opportunity to plant butterfly friendly flora; and a very, very special ceremony honoring late cat-about-the-Vortex Radius, who passed this January. – James Scott
