Jan. 29-30 Cathedral Flower Festival St. Cecilia Cathedral, 701 N. 40th St. Sat. 10 a.m.-4 p.m. and 7-9 p.m., Sun. 1-4 p.m. FREE, cathedralartsproject.org A frigid Nebraska January isn’t hospitable to very much other than tropical vacation fantasies. Luckily for local dreamers, this weekend’s Cathedral Flower Fest provides a false sense of spring and a little south of the border spin. Xalapa, Mexico, dubbed the City of Flowers, or Flower Garden of Mexico, is one of Omaha’s sister cities and the theme for this year’s event, through a collaboration with Omaha Sister Cities Association (OmahaSisterCities.com). The Mexican Consulate, Lauritzen Gardens and several South Omaha businesses also contributed to the affair. Forty-plus vibrant floral displays, lectures, live music and more, will have the cathedral pulsing with life, light, color and the promise of spring.
