It will be perceived that, out of fifty plants, twenty-eight died, and 
ten were so sickly that I threw them away: twelve only remained in 
a healthy state. 
Cinders or coal-ashes are also injurious to some plants, when the 
pots containing them are plunged in the coal-ashes, as it will appear 
by the following fact:—The varieties of Chrysanthemum sinense, 
which were cultivated in this garden in 1832, were plunged about 
two inches below the rims of their pots, at the base of a south wall, 
for flowering. After flowering (late in November) they were taken 
up with their roots hanging in all directions over the pots, and 
plunged in a two-light frame, one division of which was filled with 
cinder-ashes, and the other with common garden soil. In March, 
1833, the whole of those plunged in the ashes were pale and sickly, 
while those plunged in the soil were all robust and healthy; thus 
proving that coal-ashes, as well as cinders, are detrimental to some 
plants.— Gard. Mag.

This beautiful plant is a native of the North-west coast of America, 
whence it was introduced to the garden of the “Horticultural 
Society,” by Mr. Douglas, in 1827. 
Whether it is naturally a perennial is uncertain, it seldom sur¬ 
vives two years with us, being very impatient of cultivation. We 
have seen individual plants of it thrive and flower beautifully, whilst 
their neighbours of the same sowing, and apparently experiencing 
the same treatment, have fallen over just above the ground when 
about to flower, without any apparent cause. Not being able to 
define the cause, we remain incapable of prescribing a certain remedy 
for this sudden loss. We merely state, that we have succeeded very 
well by sowing the seeds in autumn, thus allowing the young plants 
sufficient time to get strong, before they shew a tendency to flower, 
for if they shew flower whilst the plants are weakly, they are almost 
sure to perish. 
They seem to be impatient of glaring sunshine, to obviate which 
we have planted them upon a north border in peat earth, but they
