Philadelphus — Syringa — Mock Orange. 297 



from the Northwest, is entirely hardy. It has ovate, 

 pointed foHage sHghtly serulate, and with favorable cir- 

 cumstances makes a bush ten to twelve feet high and 

 almost as broad. The flowers are produced in great 

 abundance, are almost scentless, and in terminal racemes 

 of from five to nine blossoms. This is much planted, 

 and is one of the best sorts, as it is in its prime in July 

 after most of the others have gone by. P. grandifiorus is 

 another native of the United States, having its home in 

 the South. It grows to about the same proportions, and 

 has nearly round foliage, pubescent in the early part of 

 the season, and irregularly toothed. The flowers are 

 much larger than those of most of the other species, and 

 are possessed of a delightful fragrance, not as pungent as 

 that of the coronarius which to some people is offensively 

 strong. One of the varieties, P. g. speciosissimus, is of 

 dwarf habit, and especially attractive as a garden plant, 

 particularly where space is a consideration. It grows 

 about three feet in height, and produces in great profusion 

 very large, pure white, fragrant blossoms. 



P. muropkyllus differs from most of the other species 

 in having small foliage, the individual leaves being from 

 one half to three quarters of an inch long. They are ovate, 

 lanceolate, entire, and numerous. This grows about three 

 feet high. The flowers are large, terminal, solitary, and 

 in threes. As the branches are erect and slender, the 

 plant has a very graceful aspect wherever seen. P. nivalis 

 has glaucous leaves, white on the under side and green 

 above. It is a small plant with the customary white flow- 

 ers of the genus, as is P. hirsuia, or the hairy species.
