The azaleas are easily cultivated, being very hardy, and form very attractive plants. They come in many colors and also striped, spotted, or otherwise variegated. They need a light soil of sandy loam, to which leaf-mold should be added. The foliage requires showering once a week, but the roots will rot if over watered. Flower stems form in the new wood of each summer's growth, so that the amount of bloom is apt to depend upon the annual quantity of new wood. The plants are set out in May, and need to be taken up in early autumn. They do best in the house in a temperature varying from 400 at night to 70 in the day-time.
