How can I halp my jasmine to climb up the columns on my porch w/out sliding to the ground?

Last year I planted three confederate jasmine plants in front of the columns on my back porch. The jasmine has grown profusely and is circling the columns, but unlike ivy, it doesn't have the little "suckers" to help it to cling to the smooth columns. Any advice to kep it growing up the length of the column instead of lying in a pile on the ground?
