The Canadian Horticulturist. 



or White Wood sorrel, of which the scape is one-flowered, and the petals white, 

 with reddish veins. It inhabits cold woods, and blooms in the spring. It is 

 very interesting. 



The other is O. Stricta, or Yellow Wood sorrel, and has yellow petals and 

 from two to six flowers on elongated peduncles. This is often found in meadows 

 and cultivated grounds, and is the one most familiar to our readers. It has been 

 naturalized in Great Britain. 



These flowers are easy of culture, and, by choosing out of the many varieties 

 those of different colors, a beautiful collection may be made for a hanging 

 basket, such as is shown in the accompanying engraving, for which we are 

 indebted to Mr. A. Blanc, of Philadelphia. So cultivated, they are very 

 effective for a pleasing addition to the flower window. 



They are propagated by seeds, by cuttings, 

 or by the division of the roots. 



Among the many beautiful species which 

 may be commended to t he notice of our readers, 

 is one called O. Bowie, or Bowie's Wood-sorrel. 

 It is an elegant species, and was discovered in 

 the Cape of Good Hope in the year 1824 and 

 imported to English greenhouses, from whence 

 it has been widely distributed. The flowers are 

 rose red, and, though naturally blooming in Au- 

 gust, it is quite constant in its display of flowers. 

 The accompanying illustration, Fig. 64, shows 



the habit of growth of this desirable variety.

Winter Pruning. — The American Garden says there are times when practice 

 and theory do not apparently agree, and winter pruning is a case in point. The 

 older gardeners have been taught that fresh wounds do not heal ; that disease 

 would certainly set in, causing death or permanent injury to a portion of the tree, 

 at least. Theory certainly teaches that when the inner organism of the wood is 

 exposed, the air at a low temperature will freeze the delicate parts, and death must 

 result ; yet we find nurserymen of later years pruning their trees during very cold 

 weather, on account of the personal comfort to themselves, arising from the dry, 

 firm ground to walk on, and no ill effects arise therefrom. The old adage of 

 "pruning whenever your knife is sharp," is not far from the truth after all, 

 although prejudice, at least, will incline us to defer the operation until the mild 

 days of early spring. There can be no injury to trees in winter pruning, if done 

 at times when the wood is not frozen.
