MOCKORANGE, VIRGINAL (Philadelphus virginalis) : 
This is the Mockorange with the outstanding semi-double white 
blooms. A mass of bloom in June with intermittent flowers afterwards. 
Upright slender sparsely foliated shrub that does not lend itself to 
be included in a mass border for a wall of green. It is naturally 
gawky. It can be made a little more compact by pinching out the tips 
of the lanky shoots when they are actively growing. The mass of flow- 
ers is very showy. Place in the foreground of other shrubs. We sug- 
gest to use it against the sides and rear of houses in foundation 
plantings where the building affords a background. Used there singly 
to add variety. Generally maintained at a height of about 6 feet high 
and 4 feet spread. When in groups space 3 to 4 feet apart. 
NINEBARK, GOLDEN (Physocarpus opulifolius aurea) : 
Used mainly in Colorado and Wyoming. Grows 6 to 8 feet high. 
May be controlied by trimming as a smaller shrub. Space about 4 feet 
apart. 
NINEBARK, DWARF (Physocarpus monogymus) 
A low compact shrub with good green foliage. Grows 4 to 5 feet 
high, with a spread of about 3 feet. Space 3 to 4 feet apart. Hardy 
in all our territory. May be used singly, in groups, or for trimmed 
hedges. Flowers white in late May not a talking point. A good com- 
pact shrub with good faiiage. 
PEATREE, SIBERIAN (Caragana arborescens) 
Can be cut off to grow in shrub form. Very hardy. Used mainly 
for variety in Colorado and Wyoming. Silver-green foliage. Small 
yellow flowers in May are not a talking point. Used some in wind- 
breaks. Height 6 to 12 feet, spread 6 feet. 
PRIVET, AMUR (Ligustrum amurense) ; 
Ultimate height 6 to 10 feet and width about 4 to 6 feet when 
planted east and south of here. Compact growing but inclined to be 
leggy on shrubs left to grow naturally. Foliage bright green in the 
spring changing to a deep green in the summer and up to late autumn. 
Used mostly for box hedges south and east of here. Tops will freeze 
back some winters here. Seldom. used in shrub borders. White flowers 
in June not a talking point. 
PRIVET, ENGLISH (Ligustrum vulgare) 
Ultimate height 6 to 10 feet and spread 4 to 6 feet, a stout, 
much-branched shrub, irregularly spreading and dense. Foliage bright 
green in the spring changing toa deep green in the summer and up to 
late autumn. Used as a shrub and for hedges west of here. Blights 
here and east where there is more rainfall. May be controlled for a 
lower shrub than the ultimate height. White flowers in June no talk- 
ing point. When used as a shrub in a group, space a distance apart 
equal to about 80% of the proposed maintained height. 
PRIVET, LODENSE (Lugustrum vulgare hanum) 
A dwarf growing variety of European Privet which can be used as a
