EFFECTS OF THE WINTER IN THE 

 ARNOLD ARBORETUM. 



Tlie high temperature of January 

 started the development of the flower- 

 buds of some plants, for example 

 those of the Silver Maple (Acer sac- 

 charinum) which was in full flower 

 on tlie first day of February, or 

 several weeks before the usual time. 

 January was followed by two months 

 of cold weather and frequent snow- 

 storms. The snow protected small 

 plants which without this covering 

 would probably have suffered, and the 

 number of plants that have been killed 

 or seriously injured in the Arboretum 

 is surprisingly small. The flower- 

 buds, however, of many plants have 

 been entirely or partially killed, while 

 other plants which in an ordinary sea- 

 son lose their buds have not suffered 

 and promise to yield unusual crops 

 of flowers. The flower-buds of all 

 Peach trees are killed but those of the 

 Plums and Crabapples appear to be 

 uninjured. The spring is from ten to 

 twelve days later than usual. 



Rhododendrons have suffered less 

 than they did in the winter of 1914-15. 

 Occasionally a leaf has been browned 

 or a small branch killed, but appar- 

 ently a good many flower-buds have 

 suffered and the prospect for flowers 

 is not so good as usual. Rhododen- 

 dron poiiticum. which usually suffers 

 in this climate, appears to be killed 

 outriglit. This plant which is so 

 hardy in England, where it sometimes 

 becomes a troublesome weed, has seri- 

 ously interfered with the successful 

 cultivation of Rhododendrons in this 

 part of the world, for it has been used 

 in European nurseries as stock on 

 which is grafted the hybrids and 

 varieties of other species, and the 

 hardiness and vigor of many of these 

 plants has been unfavorably influ- 

 enced by this tender stock. A little 

 hybrid Rhododendron known as 7?. 

 praecojT. "Little Gem," is perfectly 

 hardy here but it blooms so early that 

 in about nine years out of ten the 

 flowers after they open are spoiled by 

 frost. This year not a flower-bud has 

 been injured and the plants are now 

 in flower. 



Forsythias. Many flower-buds ot 

 these plants have been killed as they 

 were two years ago. In the low- 

 ground of the general shrub collection 

 the flower-buds of all the species and 

 varieties of Forsythia have been en 

 tirely killed with the exception of 

 those of the Albanian F. europaen 

 which are uninjured. If the flower 

 buds of this species are better abl< 

 to support cold than those of the other 

 species, which are all natives of cast 

 ern continental Asia, the European 

 plant sliould l)e better known ami 

 more generally cultivated. One of the 

 last plants discovered in Europe, it 

 is a vigorous, fast-growing shrub 

 with more erect stems and branches 

 than are usually found in the other 

 species of this genus. The flowers are 

 not quite so showy as those of F. 

 siispensa and its hybrids and varie- 

 ties, but they are always abundantly

i\s these Lilies are most useful during the early Winter months, and 

 for Christmas flowering, we suggest -May, June and July delivery as the 

 best time for making 'ibipments of Speciosuni.

 plant is still rare in gardens and it Is 

 doubtful if it can be found in Ameri- 

 can nurseries. 



Magnolias. The Japanese shrubby 

 species. Magnolia stpllata. is usually 



the first of the Magnolias to flower in 

 tlie Arboretum and the petals are 

 sometimes browned by a late frost. 

 This year many of the flower-buds 

 have been killed and only a few 

 flowers much reduced in size are now
