SMALL TREES AND SHRUBS. 343 



is worthy a place in every garden. There are also varieties 

 of the common Kalmia Angustifolia, or Lambkill, which 

 are very pretty. K. Angustifolia carnea, pumila, and rubra, 

 our swamp Kalmia, K. glauca and its varieties, stricta, and 

 superba, are very ornamental. Kalmia Myrtifolia is a fine- 

 leaved variety. All these are perfectly hardy. 



The Andromedas are a very pretty tribe of plants ; of 

 these, the following are hardy : A. Catesbsei, Floribunda, 

 Mariana, Polifolia, and its varieties. 



The Ledum is a very pretty evergreen, and all its species 

 are hardy. L. angustifolium, buxifolium, procumbens, in- 

 termedium, latifolium,palustre, and thymifolium. 



These are all low-growing evergreens, and very pretty 

 miniature plants. In June they are covered with small 

 white blossoms. 



We have been thus diffuse on this subject, because it is 

 one on which there is general ignorance ; and large sums 

 are annually spent in importing plants which never survive 

 the first winter. All we have mentioned are perfectly 

 hardy, and well adapted to our New England climate.
