INJURIES TO PLANTS, WINTER, 1880-81. 



ed better than in 1881. A. amaena, hybs. between this sp. and a gar- 

 den var., preserved their blossom buds and opened them securely. A. 

 mollis, stood well. A. pontica and American types and hybrids, were 

 also uninjured. Rhododendron barbatum, R. Blandfordiasflorum, R. 

 campylocarpum, R. cinnabarinum, R. dahuricum, R. ferrugineum, R. 

 hirsutum, R. lepidotum, R. maxmum, and R. ponticum hybs., R. 

 setosum, R. Thomsonii, R. triflorum. 



Observations — My obs. have been confined almost exclusively to 

 Azaleas and Rhododendrons; these plants, as is well known, are 

 principally injured by spring frosts; but during the past winter 

 some very unusual results of the winter's cold have been observable. 

 During 20 years I have never before known the blossom buds of R. 

 maximum and of R. ponticum injured in this locality ; but in the 

 winter of 1880-81, many of them were frozen through. Experience 

 has taught me that with this class of plants, it is not the amount of 

 cold which tells, but rather the time when the cold is experienced, 

 and the circumstances attending the thaws. I have been in the 

 habit of breaking off the buds and examining them and I find as a rule 

 that a mid-winter cold has little effect, but early autumnal and late 

 spring frosts do the injury. The past winter, however, has been an 

 exception to this rule, for the blossom buds of many were fairly 

 frozen through by the mid-winter's severity.
