NEW NOTES ON HYDRANGEAS. 
aH Hydrangeas now form a most attractive group of 
hardy deciduous shrubs, for in addition to the well- 
known Hydrangea hortensis, introduced to English 
gardens nearly a century since, we have several most 
=~ beautiful kinds of quite recent introduction that are as 
yet not so widely known as they should be, 
For many years the old and most popular form mentioned above 
was regarded as a greenhouse plant, and treated accordingly, and 
for along time after cultivators began to plant it in the open border 
it was not considered sufficiently hardy to be left out of doors 
without protection of some kind, and, until quite recently, it was 
common to see in gardens the Hydrangeas matted up, as if a blast 
of wind or a few degrees of frost would suffice to destroy them. 
Indeed, in some places they are still protected, and I have in my 
circle of horticultural friends several who consider the winter 
protection one of the chief points in their practice, and according 
to present appearance the strongest arguments are not likely to 
have much effect upon them. Reference is here made to friends 
who take something more than the usual degree of interest in these 
shrubs, and who can in the course of the season show their friends 
huge bushes, bearing an immense number of flower heads; and 
herein lies the difficulty of persuading them that protection is 
unnecessary. If you discuss the matter with them they at once 
say, “Look at these specimens; they are such as you do not see 
every day, and if by protecting such fine examples can be produced, 
why should protection be abandoned.” And as it is difficult to 
persuade them that care and attention have contributed more to 
their success than the assistance afforded by the protecting ma- 
terials, I usually allow the subject to drop, and leave them to enjoy 
their opinions. But if I am candid with my readers, I must tell 
them that the Chinese Hydrangea, the one so well-known, is so 
hardy that it may be left out of doors throughout the whole year, 
without the least risk of injury, excepting it be in the northern 
parts of the country where the plants do not have an opportunity 
of well ripening their wood. It is, of course, impossible here to 
consider extreme cases, and throughout the greater part of the 
United Kingdom it may be considered perfectly hardy, and steps 
taken accordingly, without any risk of the result being otherwise 
April.
