Mahonia aquifolium. - Ilex-leaved Mahonia. - This is an elegant evergreen shrub, three or four feet high, with clusters of yellow flowers, in May or June, succeeded by bunches of blue berries. The leaves are compound, with somewhat prickly points, very glossy green, inclining to purplish-brown, and, in those that are young, various shades of crimson and purple, giving the plant a very rich appearance. The foliage remains in perfection during the winter, where screened from the sun by trees, or covered with snow or straw. In autumn the foliage is very gay, as on the same plant there will be bright-green, purple, brown and crimson leaves.
