These hothouse climbers are seldom seen now. The days of short-stemmed flowers are gone, and hoyas are only found in the private collection. H. car-nosa was once a very common plant in our greenhouses, and we have all heard the dear old lady tell us hundreds of times that her "wax plant did not flower."
H. carnosa and H. bella are the two best known. The latter is a beautiful but more delicate plant. They root easily in the spring from the tops of the growths. If a specimen is wanted they should be trained on a wire frame. They like plenty of sun and ventilation in summer time, and in winter should be given a rest by keeping rather dry and in a house at about 50 degrees.
Their waxy flowers, in fine umbels, are very pretty, but they are not a florist's flower.
