Last March, Su Teatro was making its way through the start of the run of “The War of the Flowers” when the pandemic shuttered everything. Its remounting of the original musical about a group of Mexican-American women fighting to unionize at a Brighton carnation farm arrives as a gift both purposeful and entertaining. As Guadalupe “Lupe” Briseño, Felicia Gallegos Pettis anchors the show and imbues it with the determined spirit of the labor leader who was inducted into the Colorado Women’s Hall of Fame last year. The musical joins a first-rate slew of currently running and upcoming works tackling and teasing Colorado history with vim, vision and rigor.
