WINTER INJURY TO PLANTS IN THE GARDEN 
The extreme severity of the winter 1917-18 has caused a 
great deal of injury and in some cases death to the woody 
plants at the Garden which under ordinary conditions sur- 
vive the cold successfully. The rather unusual abundance 
of snow, however, was instrumental in protecting the roots 
of the woody and particularly the herbaceous plants so that 
the latter suffered much less than might have been expected 
from the unusual season. The abnormal conditions have 
served a useful purpose in indicating the thorough hardiness 
of certain planting material as well as the need of substitu- 
tion for the more tender plants. 
The killing back to the ground of most of the California 
privet (Ligustrum ovalifoliwm)—the plant almost untiver- 
versally used for hedges in St. Louis—was surely an im- 
pressive demonstration of the necessity for a substitute for 
this favorite. Fortunately, Amoor privet (Ligustrwm amur- 
ense) is hardy, easily clipped, and fully as effective, and 
should be acai in place of the California variety. The Jap- 
anese barberry (Berberis Thunbergii) may also be success- 
fully substituted. 
The roses, as a whole, have suffered more damage than 
any of the other plants. In ex locations the — 
hardy climbers have been killed back to the ground, wit 
the exception of Rosa Hugonis, “Crimson Rambler,” ‘‘Kal- 
mia,” and a few others. Despite the thorough protection 
given the standard tree roses, the hybrid perpetual and
