"Poet's Choice."

U.S. Poet Laureate Robert Hass. He's written several books of poetry including "Praise" and "Human Wishes." He also edited "The Essential Haiku: Versions of Basho, Buson & Issa."

Hass says he is overwhelmed by images; the point of art is to make sense of it. He joins Fresh Air to talk about how memory and invention influence his poetry. A new collection, called Human Wishes, will be published later this year.

Natasha Trethewey was awarded the Pulitzer Prize for Native Guard, her most recent collection of poetry. The title refers to a regiment of African- American soldiers who fought for the Union in the Civil War.

Trethewey grew up the child of a racially mixed marriage in Mississippi. Her mother was murdered by her stepfather; these, along with the South and its singular ways, are recurring themes in her poetry.

Trethewey teaches creative writing at Emory University. Native Guard is her third collection.
