Jujube (Zizyphus Jujube). Rhamneæ.
Seeds and cuttings.
Juncus (Rush, Bulrush). Junceæ.
Seeds. The perennials may be increased by division.
Juneberry (Amelanchier Canadensis, var. oblongifolia). Rosaceæ.
Increased by using the sprouts which form freely about the old plants; also by seeds.
Juniperus (Juniper, Red Cedar). Coniferæ.
Increased readily by seeds, which, however, often lie dormant until the second year. They germinate more readily if the pulp is removed by maceration or by soaking with ashes for a few days. Green cuttings, in sand under glass, root easily; or mature cuttings may be taken in fall and placed in a cold-frame, in which they will need little protection during winter. Some varieties require a long time to root. Most of the named varieties may be grafted on imported Irish stocks, which are much used in some parts of the country. They may be veneer-grafted and handled in a cool house.
Jurinea. Compositæ.
Increased in spring by seeds or by divisions.
