ON THE CULTURE OF LEUCADENDRON ARGENTEA. 
In how few collections of greenhouse plants this splendid growing old species is 
found ! It has always been considered difficult to keep, and more so to propagate it ; 
hence its scarcity : although perhaps it is not easy to conceive a more admirable 
object than is a large specimen of this plant. 
It requires for a soil, two parts good heath-mould, and one part light sandy loam, 
not broken fine, but merely chopped together. 
In potting, drain well with broken potsherds and charcoal ; also mix pieces of 
charcoal and freestone about an inch square through the soil. These will retain 
moisture, and prevent the roots suffering immediately from drought, which they are 
very liable to do ; they also answer other important purposes. Do not cramp the 
roots, as by such treatment they are sure to suffer. 
Over- watering and drought are two extremes which must always be avoided ; the 
plants cannot endure either. The roots being tender, water must be administered 
at all times with care, but especially in winter ; drought, however, is more injurious 
than over-watering. The leaves being so thickly clothed with silky hairs, 
syringing is usually fatal to the foliage, and sometimes to the branches, it is best to 
entirely dispense with that operation. 
Its situation in the greenhouse should always be cool and dry ; heat, or an 
atmosphere loaded with moisture is always injurious. If placed out of doors during 
the summer season, they either suffer at their roots by drought from exposure to too 
much sun and air, or they perish from over-moisture by rain, or the roots are 
lacerated by the entrance of worms into the pots ; or lastly, the tender foliage is 
scorched or bleached by the various changes in the atmosphere. Always, therefore, 
keep these plants in the greenhouse.
