Menziesia furnishes several brilliant and elegant species and varieties. M. polifolia and its varieties, of which there are now eight or nine, are a beautiful and showy group of summer-flowering dwarf shrubs. The dark purple, the white, named globosa, and the nana varieties, are the best. The latter flowers from June far into the autumn, and is quite a gem. The charming and rare little M. ceerulea is more difficult to grow and keep than the foregoing sorts, but it is well worth a little trouble. It succeeds best in sandy peat on rockwork, in a rather moist situation. M. empetrifolia is a most beautiful dwarf species from North America, with rosy purple or pale-red flowers, which must be cultivated in the same way as the last-named species.
