This is a neat hardy herbaceous plant, always pleasant to look upon. It grows in rounded graceful masses, with numerous stems, clothed with narrow linear leaves of brightest green; this green eventually changes into red and then yellow in autumn, and in all these mutations it is a softly charming plant in pots. It grows about 9 inches high, each stem terminating in an umbel of small greenish-yellow flowers, accompanied, as is the fashion of the order to which it belongs, with conspicuous bracts broadly egg-shaped, which are persistent, and add much to the beauty of the plant in autumn by the depth of soft red colour they assume. The plant is easily grown in pots out of doors, in any ordinarily good loam, and should be divided every spring, and the soil renewed in the pots. In autumn, before frost comes on, it should be lifted into a cold frame, so as to preserve it as long as can be, whence it may be taken to the rooms or houses which it is designed to assist in ornamenting.
