The mahonias are very handsome evergreen shrubs spreading usually by suckers, with large leaves and yellow flowers in conspicuous panicles appearing in spring and followed by dark blue bloomy berries. Most of the species are tender, but M. repens, M. Aquifolium, M. nervosa. M. pinnata var. Wagneri are hardy as far north as Massachusetts, but the foliage is liable to be scorched if exposed to the winter's sun, though M. repens is more resistant and is rarely burned. M. japonica will succeed if planted in sheltered situations. M. pinnata is a most beautiful evergreen species, but it requires protection from cold winds, and the winter's sun. M. repens is the best evergreen species we have. It spreads rapidly and the foliage is rarely burned, and the numerous clusters of showy yellow flowers render it most attractive at the end of May. They prefer a humid soil and a position sheltered from strong winds and from the hot sun. They are easily transplanted and some, particularly M. repens and M. nervosa, spread considerably by suckers. Propagation is by seeds sown soon after maturity or stratified and sown in spring, or by suckers which are freely produced in most species, also by cuttings of half-ripened wood under glass and by layers.
