The trailing habit of Verbenas makes them superb in hanging baskets. This variety is likely 'Purple Homestead' (Verbena canadensis 'Purple Homestead'), a big favorite in our climate. It features beautiful dark purple flowers all season, prefers full sun, tolerates some drought, grows to 6-12 inches tall and 3 feet wide, and attracts bees, butterflies and birds. It's also perennial in the Ozarks, being hardy to -10 degrees. It's clearly a winner.
