HYDRANGEAS : NEW AND OLD. 
The genus hydrangea is a fairly extensive 
one that, in a state of Nature, occurs prin¬ 
cipally in North America and in North- 
Eastern Asia, including Japan. Far and 
away the most popular of all is Hydrangea 
Hortensia, which forms such a feature of 
many gardens in the south and west of this 
country, and in other places, especially in 
proximity to the sea, for it seems to favour 
not too severe, have, however, been at dif¬ 
ferent times dealt with in the pages of the 
Gardeners’ Magazine, notably in the issue 
for August 10, 1912. Such being the case, 
1 need say nothing further on that point, 
but confine myself to mentioning a few of 
the most distinct of the recognised varieties, 
and the numerous garden forms that have 
within the last few years been raised on the 
goodly show. These last are of a rose 
colour, becoming, in some cases, alm^ 
crimson with lage. 
In H. H. Mariesi, the main feature is the 
immense size that the sterile blooms attain 
They are of a deep pink colour, and are 
limited to a scattered few around the out 
side of the flower cluster. The variety 
Veitchi is a counterpart of this except tha'r 
the sterile blooms are white. H. H. nigra 
also known as cyanoclada and mandchurica' 
derives its name from the bark of the young 
shoots, being of a shining black tint^ very 
different from the ordinary forms. ’ The 
flowers, borne in massive heads, are of a 
bright rose colour. It has long been a 
favourite for pot culture. 
H. H. Otaksa is one of the l>est of the

a near association with “ the briny.” A 
fine specimen in a Torquay garden is here¬ 
with illustrated. The neighbourhood of the 
sea is, however, by no means essential to 
its well doing, as delightful specimens may 
be met with in the home counties where con¬ 
ditions are favourable; and grown in i>ots 
for decorative purposes, it figures largely 
in Covent Garden Market over a consider¬ 
able peri^ of the year. In addition to 
this, specimen plants grown in large pots 
or tubs are exceedingly valuable for stand¬ 
ing on terraces or in similar positions dur¬ 
ing the summer montlis. 
The use of Hydrangea Hortensia itself as 
a decorative subject, and its ornamental 
features out of doors wdiere the weather is

largely growui. 
Rrominent among the varieties that havf 
been introduced from Japan, and of whicl 
some have before now' been looked upon as 
true species, is H. H. Lindleyi, one of th( 
most distinct of all, differing as it does ir 
many ways from the typical kind. Th^ 
sheets are far more slender, and the leaves 
and flower clusters much smaller. Thf 
flowers are produced from the axillary a^ 
well as terminal buds, so that even should 
the point of the shoot be injured by frost 
there will be, as a rule, a fair display. The 
major portion of the blossoms are*^ small, 
fertile ones of a bluish colour, but there arf 
enough of the large sterile ones to make . 
Hortensia class; that is to say, it i 
a very good form of the type,but 
differ in any marked manner thereti 
H. H. rosea is somewdiat after the 
of Lindleyi, mentioned above, 
the flowers are all, or nearly all, sterile 
of a rich,bright rose colour. H. 
of rather weak grow'tli, is remarkable _ 
the fact that the sterile flow ers nrf ®. 
or less double, w hich feature ^

Japan by way of the Fnited Sta^s

yeai-s ago, grown almost to the exc
