360 THE NURSERY-MANUAL 



Mertensia (Lungwort). Boraginacecr. 



Seeds are sown as soon as ripe or the following spring. Established 

 plants may be divided, although this is not advisable. 



Mesembryanthemum (Fig-Marigold. Ice-Plant). Aizoacece. 



Propagated easily by seeds sown under glass ; by pieces cut off 

 and laid in the sun two or three days and then put in sand as 

 cuttings. The common ice-plant (M. crystallinum) is grown as an 

 annual from seeds. 



Mespilus (Medlar). Rosacece. 



Stocks are grown from stratified seeds, and the plant may be 

 worked on these, the thorn and the quince. Seeds sometimes lie 

 dormant until the second year. 



Metrosideros (Bottle-Brush). Myrtacece. 



Seeds and cuttings. The florist's plants so named are increased 

 by cuttings of the young growth in early spring, set out in good soil 

 at the end of May. 



Michelia. Magnoliacece. 



Propagated by seeds and cuttings of ripened wood in summer 

 or fall, in sand under glass, one or two leaves being left on. Seeds 

 are handled as in magnolia, to which the species are often referred. 



Miconia, or Cyanophyllum. Melasiomacece. 



Increased by seed ; by cuttings or eyes of firm wood in sand, with 

 bottom heat and shaded from the sun ; also by ringing the tops of 

 old plants and covering with sphagnum moss ; when roots appear, 

 sever from the old plant and pot on. 



Mignonette (Reseda odorata). Resedaceoe. 



Grown from seeds, which may be started indoors in spring or 

 sown in the open where the plants are to remain. For florist's use as 

 a crop for winter and spring and early summer bloom under glass, 

 the seeds are started for succession early in July, August and 

 September. Plants of the September sowing should bloom till the 

 following midsummer and supply seed for resowing. Seeds are 

 usually sown on the benches where the plants are to bloom, several 

 of them dropped at points about 6 by 8 inches ; all but two to four 

 are removed by thinning. The mignonette is annual, usually 

 classed among the hardy kinds.
