Snowberry 



Native of northern North America 

 Family Caprifoliackae; Honeysuckle) Family 



Symphoricarpos racemosus laevigatus 'Pernald, Rhodora. 7 : 167. 1905. 

 Symphoricarpos albus laevigatus Blake, Rhodora 16: 119. 1914. 



A shrub up to four feet tall, with erect or ascending purplish gray 

 or gray branches, somewhat drooping glabrous branchlets, and white 

 and rose flowers which are followed by snow-white fruit. The 

 opposite leaves, glabrous except for the ciliate margins, have 

 petioles less than a quarter of an inch long; the blades are oval or 

 nearly orbicular, obtuse at each end, up to one and a half inches 

 long and an inch wide, and are paler beneath. The flowers, about 

 three eighths of an inch long, are in few-flowered axillary clusters 

 toward the end of the branches, forming a somewhat interrupted 

 spike; the calyx is superior and has short lobes; the corolla is bell- 

 shaped, about a quarter of an inch long, is somewhat swollen at the 

 base, pubescent within, and in color white and rose, the obtuse or 

 acutish lobes about half the length of the corolla. There are five 

 stamens, which are shorter than the corolla, as is also the style. 

 The fruit is of a snowy whiteness, often a half inch or more in 

 diameter. 



This native shrub is found from Quebec to Washington, and south 

 in the mountains to Virginia. It is of the easiest culture, accom- 

 modating itself to almost any environment, thriving in sun or shade ; 

 in fact, so prone is it to spread by means of suckers that its tendency 

 in this direction must be checked if other shrubs in its neighbor- 

 hood are to survive. This habit of making suckers would indicate 

 its ease of propagation, and such is the case. It may also be 

 propagated by means of seeds, and by hard and green-wood cut- 

 tings. The specimen from which the illustration was prepared has 

 been in the collections of the New York Botanical Garden for many 

 years. This is one of the best of our shrubs on account of its 

 handsome white fruit, which occurs in great abundance and persists 

 well through the winter. 



Symphoricarpos is a genus of about sixteen species, all but one 

 natives of North America, where they extend as far south as Mexico, 

 the exception being found in western China.
