“ tfttprtual 
CamUotu” 
The above is the title of a book written 
by Mr. Montagu C. Allwood, F.R.H.S., 
of Bush Hill Park, dealing with the culti¬ 
vation of what is generally known as the 
American Carnation. It is a race of tree 
Carnations differing considerably from 
the European race, and in many in¬ 
stances truly perpetual flowering, but 
some of them are only remontant. 
It is the first book that has been written 
in this country entirely devoted to the sub¬ 
ject of the American Carnation, which 
has been so engrossing to the British pub¬ 
lic for the last two years or so. Mr. 
Allwood is thoroughly acquainted with 
his subject, and therefore speaks like one 
having authority. He deals with the sub¬ 
ject from various points of view, whether 
cultivated in pots planted out on benches 
in glasshouses or planted in the open air. 
An illustration shows a houseful of Car¬ 
nations grown upon benches in the same 
manner as that extensively practised by 
the American growers. Readers need 
not regard the subject as a difficult one 
because mostly grown under glass, nor is 
the plant so tender as the treatment given 
it would seem to indicate. As the plant 
flowers chiefly during winter, it could not 
possibly give satisfaction in our climate 
at that period without protection. 
After giving a plea for the perpetual 
flowering Carnation, the writer then dis¬ 
cusses the origin of this perpetual flower¬ 
ing race, as well as that of the British 
tree Carnations. After this he drops into 
cultivation, pure and simple, dealing with 
the propagation of the plant by cuttings, 
showing also how amateurs can carry out 
this operation for themselves on a small 
scale. For the sake of comparison, the 
American system of propagation is also 
discussed. The plants are then dealt 
with successively from the cutting pot to 
the flowering period, and a chapter or 
two deal with the houses that are suitable 
for growing Carnations, with a descrip¬ 
tion of what he could call a perfect Car¬ 
nation house. Indoor and outdoor treat¬ 
ment of plants during summer come in for 
discussion, then the housing and watering 
in winter. Tying, staking, stopping, or. 
pinching form the subject of other chap¬ 
ters, and above all the author advocates 
thoroughness in everything relating to the 
cultivation of this fascinating and popular 
winter flowering subject. There are also 
chapters on insect pests and fungoid dis¬ 
eases, with a calendar of operations. Al¬ 
together the book of. ip pp. is brimful 
of information on this subject, and may 
be obtained from Messrs. Hugh Low and 
Co., Bush Hill Park, Middlesex, for 2s. 
and cost of postage.

Primula. 
(Primula verticillata.) 
The above is one of the most distinct 
of the Primulas in cultivation, but un¬ 
fortunately it is not quite hardy, other¬ 
wise it would be universally cultivated. 
As it is, it may be grown to perfection 
in a cold frame in the southern and more 
favoured parts of Britain and in a green¬ 
house in any part of Britain. It merely 
requires that frost be excluded to enable 
it to- come through the winter. It is 
also advantageous to have it sheltered so 
that rain cannot fall upon the plant to 
wash off the mealy powder w'hich covers 
every part of the stem. 
It was introduced from Arabia in 1870, 
and that would account for its not being 
quite hardy, and the extreme mealy char¬ 
acter of the foliage shows that it is un¬ 
suited to a wet climate such as ours about 
the time when it is in bloom. It is there¬ 
fore a plant that must be cultivated under 
glass, but requiring a minimum of arti¬ 
ficial heat, but its distinctness makes it 
well worthy of any trouble in this respect. 
The flowers are also strongly and 
deliciously scented and bright yellow. 
It is supposed to be one of the parents of 
P. kewensis, which makes such a showy 
winter and early spring flowering subject.

Papaver Princess Ena. 
The above is a variety of P. orientale 
bracteatum,though somewhat smaller than 
usual and vastly more refined. The 
petals are, indeed, of a beautiful shade 
of orange-salmon, with a mass of black 
stamens in the centre. The colour is, 
therefore, both bright and distinct, which 
cannot be said for some of the varieties 
already in cultivation. We describe it as 
refined because the glaring red of the 
ordinary form has here given place to the 
hue above mentioned. An Award of 
Merit was given at the Temple Show when 
it was exhibited by Mr. Amos Perry.
