THE NURSERY LIST. 233 



(Enocarpus. Palma. 



Propagated by seeds or by suckers. 



(Enothera, including Godetia (Evening Primrose). Onagra- 



necr. 



Seeds may be sown in spring or summer. Divisions may 

 be made. Cuttings of perennials should be placed in a cool 

 f rarne in the early part of the season before flowering begins. 



Okra, Gumbo (Hibiscus escttlentus). Malvacece. 



Seeds, sown where the plants are to stand, or started in 

 pots often in the north. 



Olax. Olacinetc. 



Grown from cuttings of firm or mature shoots in heat. 

 Olea. Oleacece. 



The ornamental species are grown from cuttings of ripened 

 shoots, either under frames or in the border, and also by 

 seeds. For propagation of O. Europcea, see Olive. 



Oleander. See Nerium. 

 Olearia, Eurybia. Composite. 



Seeds. Readily increased by cuttings of growing shoots 

 placed in a frame. 



Oleaster. See Elaeagnus. 



Olive (Olea Europcca). Oleacece. 



The olive is grown in large quantities from seed, especially 

 in Europe. The pulp is removed by masceration or by 

 treating with potash. The pits should be cracked or else soft- 

 ened by soaking in strong lye, otherwise they will lie dor- 

 mant for one or two years. Cuttings of any kind will grow. 

 Limbs, either young or old, an inch or two inches in 

 diameter, and from one to two feet long, are often stuck into 

 the ground where the trees are to grow, or they are some- 

 times used in the nursery. Green cuttings, with the leaves 

 on, are often used, being handled in frames or in boxes of 

 sand. Chips from old trunks, if kept warm and moist, will 

 grow. The olive is often propagated by truncheons of 

 trunks. A trunk two or three inches in diameter is cut into 

 foot or two foot lengths, and each length is split through the 

 middle. Each halfisplantedhorizontally, bark up, four or five 

 inches deep, in warm moist soil. The sprouts which arise may 

 be allowed to grow, or they may be made into green cuttings.
