In time, the centers of clumps become hollow or dead and need to be divided. This plant is unusual in that the flowers will be arranged in whorls in the axils near the tip of the stem. Propagate monarda by seed or division. The seed germinates in 15 to 20 days at 60 to 70 degrees. Divide in the spring and save divisions from the edge of the clump.
