32 FLOWERING AND ORNAMENTAL SHRUBS. 



two species of this very ornamental shrub from Mis- 

 souri, introduced by Lewis & Clarke ; they are quite 

 hardy, and flower in great profusion. 



Robinia glutinosa, and Robina hispida, the former a 

 pretty large shrub, with large bunches of flowers in 

 great abundance, the other a smaller shrub ; they are 

 both of them worthy of a place in all large collections. 



Robinia pseudo-acacia, or Yellow Locust tree.* This 

 is superior to any other kind of wood for ship-trunnels, 

 mill-cogs, and fence-posts, as well as for various other 

 purposes. Its culture is very easy, and may be pro- 

 pagated in great abundance, by sowing the seed in 

 March, April, or May, in a bed of good sandy loam r 

 which is its favourite soil, and covering half an inch 

 deep. Previous to sowing, put the seed in a basin, 

 pour on scalding water, and let it stand all night ; pick 

 out such seeds as are swollen, and plant them imme- 

 diately ; next evening repeat the same process, with 

 such as have not swollen the first night, mix the 

 whole, and sow them ; they will come up in the course 

 of the following month numerously ; for no seeds grow 

 more freely, notwithstanding what some may say to 

 the contrary. When a year old, transplant them out 

 of the seed-bed into nursery rows, four feet distant, 

 and plant from plant one foot in the row. Having 

 two or three years 5 growth in these rows, they may be 

 planted successfully in any warm and tolerably rich 

 sandy ground. They may also be propagated by 



* This tree is introduced here rather on account of its usefulness 

 than its beauty, though the latter is very considerable.
