PHYSOCARPUS — Ninebark 
Physocarpus Opulifolia Nana (Dwarf Ninebark). This plant is 
rapidly becoming one of the most popular hedge plants. Its irregular 
growth makes it an ideal plant for that purpose. Small foliage, deep 
dark green and we know of no disease that will bother it. 
RHAMNUS — Buckthorn 
Catharticus. The old Buckthorn, Rhamnus Catharticus, is almost 
too well known to need any description. It is still a good hedge and for 
a really protective hedge, probably stands alone. It should not be 
planted where oats are grown. It is an alternate host of the oat rust and 
should be kept from a quarter to half a mile away from oat fields. 
Davurica (Dahurica). A new Buckthorn which has several advan- 
tages over the Rhamnus Catharticus. One is that it is entirely free from 
the oat rust. Another is that it grows very compact, branching out from 
the ground up. It is a slower grower, leaves are somewhat broader and 
longer than that of the Catharticus. We believe that Davurica will 
make a place for itself. 
Frangula (Glossy). Height 10 to 12 feet. Upright, hardy shrub 
used for hedging. Glossy green leaves, more round than the Catharticus. 
Berries are red changing to black. 
SPIREA 
Arguta. Of all the Spireas, the Spirea Arguta is outstandingly 
adapted to a medium-growing hedge. It stands trimming well. Grows 
very compact and can be made to look like a wall of green from the 
ground up. In the early spring its white flowers add to its attractiveness. 
DISTANCES FOR PLANTING 
One of the questions we have so often been asked is how far apart 
these various varieties should be planted. We give the following schedule 
as a guide. When we speak of hedges in this connection, we refer to a 
trimmed hedge.
