Fortune Mahonia. This is by far the most delicate of the old known species of Mahonias. It has soft leaves which somewhat resemble bamboo. It blooms with 3 to 4" long racemes of yellow flowers from late August into early October. In milder regions it will produce small blue berries. It is a great filler plant in the shade garden, which has its greatest effect when massed. It usually grows only 3 to 5'. Since it rarely produces viable seed, it is best propagated from cuttings in the fall, and it roots quite easily.
