Muehlenbeckia, Sarcogonum. Polygonaceæ.
Seeds. Increased usually by cuttings, taken in early summer in a frame.
Mulberry (Mortis alba, M. nigra and M. rubra). Urticaceæ.
New sorts are grown by seeds, which should be handled in the same manner as small fruit seeds. Named varieties are multiplied by cuttings of the root, or of mature wood, and sometimes by layers. The tree may also be budded or grafted by ordinary methods.
The common white mulberry was formerly used as a stock for named varieties, but Russian mulberry seedlings are now much used. The stocks may be top-worked out-doors, or root-grafted in the house. They are commonly crown-worked, however, in the house in winter, the stocks being grown in pots or boxes for the purpose. They are then kept under glass until the weather permits them out-doors. By this method fine specimen trees are procured, but they are readily handled by cheaper methods. The weeping and other ornamental sorts are now worked upon the Russian mulberry.
Mulberry, Paper. See [Broussonetia].
Mullein. See [Verbascum].
Musa (Banana, or Plantain-tree). Scitamineæ.
Seeds may be sown in heat during spring. Suckers are used for those species which produce them. Many of the species do not produce seeds freely, and suckers must be relied upon. See [Banana].
