CULTURE OF HARDY DECIDUOUS AND EVERGREEN SHRUBS. 
made good roots, it is advisable to allow them to remain where they are until the 
following- spring-. 
When the layers are separated, pot them in 48-sized pots, filled with a mixture 
of sandy loam and peat, or peat alone, place them in a frame, and keep them 
close shut down until they begin to grow ; then gradually admit air, and treat the 
layers like greenhouse plants, potting as they require it until they are established, 
and have grown to a good size ; then plant them in suitable situations, and they will 
speedily show flower. 
The seeds imported from America should be sown immediately on their arrival, 
in pots or pans filled with light sandy loam and peat, or peat alone, covering the 
seeds very lightly. Place the pots in a gentle heat, and they will soon begin to 
vegetate. When they are of a sufficient size, plant them out into 60-sized pots, 
one plant in each pot ; replace them in the frame, and shade them until they have 
begun to grow. When they have become established take them out of the frame, 
and treat them whilst small in every respect like greenhouse plants ; when thev 
have grown to a good size, plant them finally in the situations where they are to 
stand permanently. 
MALACHODENDRON. 
M. OVATA. This beautiful tree is a native of North America, where it is found 
growing on mountains. The flowers are cream-coloured and of a large size. It is 
hardy, but requires a warm and sheltered situation, otherwise the unripe wood is 
often killed in winter, and this causes the plant to flower weakly. A mixture of 
loam and peat is the best kind of soil for it ; and it may be increased both by 
cuttings and layers. Let the cuttings be made of the ripe wood, and planted in. ! 
autumn on a warm south border under a hand-glass in sand ; or they strike quicker 
if introduced into a gentle heat. The best time for pegging down the layers, is j 
early in spring ; they strike in less time if they be tongued on the upper side, and | 
the branch slightly twisted. 
PHILADELPHUS. 
P. GRANDiFLORUS. This is the handsomest of this genus; it is a native of 
North America, where it is found growing on the banks of rivers. It is perfectly 
hardy, and will grow in almost any soil and situation, forming a spreading shrub 
about six feet or more high ; and is easily propagated by layers. 
P. HIRSUTUS. This shrub grows from four to five feet high ; like the last, it is 
a native of North America, where it was discovered by Mr. Nuttall. It thrives in 
the shrubbery in any common garden soil, and is propagated like the last. 
P. coRONABiUS, or Commou Syringa, greatly resembles the others, grows about 
five feet high, and is delightfully fragrant when in bloom. It may be propagated 
like the last. 
PRUNUS. 
P. CANDicANS. This is a delightful hardy deciduous shrub, growing about six 
or eight feet high. It is very easy of cultivation, and in May and June, when in 
full flower, is a perfect picture, the white flowers nearly hiding the young leaves, 
which are beginning at that time to cover the branches. It may either be pro- 
pagated by layers, or by budding and grafting on the common plum stock.
