situations, even if it does not prefer them. This charac- 

 teristic makes it a valuable acquisition, for almost every 

 owner of an estate finds places which it is difficult to 

 cover for want of sufficient sunshine. Under favorable 

 conditions the bush is said to grow six to eight feet high, 

 but it is usually much lower. Some of the botanists have 

 been inclined to consider 6 1 . ari&folia as a variety of S. 

 discolor, instead of being a distinct species, and some are 

 even doubting whether it is a true spiraea at all. These 

 are calling it Holodiscus discolor. A rose is just as sweet 

 by any other name. 



S. regeliana, though not widely distributed, is a good 

 plant. It has dense panicles of pink blossoms about the 

 first of July, and one of its distinctive peculiarities is that 

 during the summer new stems shoot up which blossom 

 late in the season, thus prolonging the period of flowering 

 to autumn. It grows from three to five feet high and is 

 hardy. 



S. cana is one of the smaller spiraeas, seldom rising 

 more than two feet, and broadening its diameter into a 

 well-rounded bush as large across as it is high. It is a 

 native of the Croatian Alps, and appropriately named, inas- 

 much as the foliage takes on a grayish hue and in some cases 

 becomes almost white. For this reason the tiny blossoms 

 are less conspicuous than they might otherwise be, as they 

 also are white and scattered along the stems and branches 

 in great profusion. Where indigenous it grows freely 

 among the rocks and in dry and barren places which 

 there abound, and is doubtless the best adapted to such 

 situations of all the spiraeas. It is in use in England,
