204 PRACTICAL PLANT PROPAGATION 



MORUS Continued 



CUTTINGS. The Russian type, M. alba, roots easily; the wild one, 



M. rubra, and Downing's Everbearing do not. 



*GRAFTING. M. rubra and M. alba make the best stocks for Downing. 

 . Weeping varieties are grafted at height of five or six feet above 

 the soil. Grafting is practiced in early April. Root grafting in 

 Winter may also be used. 

 MYRICA. Wax Myrtle 



SEEDS. Grow slowly. Sow in Spring. 

 SUCKERS. Especially M. Gale. 

 NANDINA. Heavenly Ramboo. 



SEEDS. Obtained from California. Germinate in three months. 

 NECTARINE. 



Same stock and method of treatment as for Peach, page 137. 

 NERIUM. Oleander. 



CUTTINGS. Hard wood. Soft wood rooted in water easily. Take 



cuttings after flowering. 

 LAYERS. Chinese layers are successful. 

 NEVIUSIA. Snow Wreath. 



This is a Spiraea without petals. 

 CUTTINGS. Green wood cuttings under glass. 

 DIVISION. Successful. 

 NYSSA. Sour Gum. Tupelo. 



*SEEDS. Collect in Autumn, free of pulp and sow immediately; or 

 store in damp sand during Winter. Sow seeds in flats, they take 

 a year to germinate. 

 GRAFTING. Weeping form grafted on type. 



The trees are difficult to transplant and should be raised in pots. 

 OLEA. Olive. (See Osmanthus.) 

 CUTTINGS. From Fuller we learn : 



In warm climates, where the Olive flourishes, the cuttings are planted 

 in the open ground in the Autumn. In European countries large 

 truncheons or cuttings are used instead of those of moderate size or 

 lengths, but for no better reason than because it is the general practice 

 or custom. Chips cut from an old Olive tree stem will readily produce 

 sprouts if planted in a warm soil and kept moist; in fact, the entire 

 surface of this tree will produce adventitious buds very freely, if placed 

 in a position to receive heat and moisture. 



ORANGE. 



RUDDING. Indoors. May be budded at any season- when they are 

 making active growth. Use round bud wood rather than flat, 

 and propagate from bearing trees. 

 OREODAPHNE. Umbellaria. California Laurel. 



SEEDS. Keep moist from time they are collected until sown. 

 OSMANTHUS. Sweet Olive. Also called Oka fragrans. 

 SEEDS. Not easily obtainable. 



CUTTINGS. Half-ripe wood late in Summer or Fall. 

 RUDDING. May be budded on Privet. 

 OSTRYA. Ironwood. Hop Hornbeam. 

 SEEDS. Sow as soon as ripe or stratify. 

 GRAFTING. May graft the varieties on common species.
