Move over March Madness and make way for March grandness — the annual hanging of the nasturtiums at the Isabella Stewart Gardner Museum is on its way, with vines that can be 20 feet long.

Today on The Culture Show, the museum's director of horticulture, Erika Rumbley, joins host Jared Bowen to talk about the annual event, which includes a Nasturtium Party on April 3.

Next up, 15 years ago the street artist Shepard Fairey officially crossed the threshold into fine art with his first museum exhibition right here at the Institute of Contemporary Art, Boston. The exhibit was curated by The Culture Show contributor Pedro Alonzo. What did it mean for Fairey’s street cred? What trails did he blaze? Alonzo joins the show today to talk about about Fairey’s legacy and where street art lives today along the spectrum of counterculture, conventional and commercial art.

Finally, Mary Grant, president of MassArt, weighs in on the art of sustainability both in and out of the classroom.
