The rootstocks of the common British Hop find a good sale in spring, and are put up in boxes for market during the season. The female kind is most appreciated, as it produces the large bunches of greenish-yellow scale-like flowers during the summer months. The Hop grows in any good garden soil, and is easily increased by division. The Japanese Hop (H. japonicus) is an ornamental annual species, having strong-climbing hairy stems 15-20 ft. long, and five- to seven-lobed leaves. There is also a variegated form worth growing. As both can be raised easily from seeds sown in heat in March, it is possible to have young plants ready for sale and hardened off by the middle or end of May.
