shrub from 3 to 6 feet high with broadly oval flat glabrescent 

 leaves, bright green beneath. The flowers are large, campanu- 

 late, in compact rounded clusters, pink, deep rose, or with a 

 tinge of violet and spotted on the superior lobe. The varieties 

 are numerous, and, as well as those of the last, very desirable 

 on account of their flowering in Summer, when there is no 

 danger of the blooms being injured by frost.

 clusters ; petioles long. A native of Siberia, flowering in 

 Summer.

winter only, oval-oblong, glabrous above in the adult stage, 

 and rusty-tomentose beneath. Flowers solitary or few together, 

 purple or violet, appearing in February before the new leaves
