We have collected this large number of species and varieties for 
several reasons. In the first place, we want ‘to become familiar with 
practically everything available in the Rhododendron group so that 
we will know which ones are the best for various purposes. In 
some ways it might have been advisable for us to pick out a dozen 
or so of the best varieties and give our entire attention to propagating 
large numbers of these. However, when we consider that there 
are almost 1,000 species of Rhododendrons and several thousand va- 
rieties of Rhodcedendron hybrids and Azaleas which have been named 
and introduced, it will be readily seen that a dozen or so varieties 
would give a very poor representation of such a large and varied 
group. Furthermore, who would be able to name the best dozen 
or so varieties? The fact that certain varieties are being sold by var- 
iouS nurserymen in large numbers does not necessarily mean that 
they are the best. 
As our collection develops it becomes more and more evident 
that no one can pick out a dozen varieties which would adequately 
represent all of the types available. We have varieties which blos- 
som in February and from then on others bloom each month until 
July, and sometimes into August. Some produce a few flowers in the 
Fall. There are tiny rock garden plants only 2 or 3 ins. high with 
very small leaves, and other large, free-growing plants with large 
leaves which, if given ideal conditions, would eventually make trees 
many feet high. There is a wide range of foliage, type of growth, 
and color and size of flowers. It is our feeling that as these less 
well Known species and varieties become better known, they will 
play a much more important part in American gardening. Use of the 
dwarf, rock garden types has hardly been started in this country. 
It is our hope to have here at Cranguyma Farms a collection which 
people can study and from which they may choose a great range of 
plant material for all sorts of gardening uses.

Rhododendron Culture 
There is no denying that Rhododendrons do require special con- 
ditions in order to thrive as they should. However, we are finding 
every year that people in additional areas where Rhododendrons have 
never been grown before can grow them successfully if they watch 
a few details. Rhododendrons require an acid soil but this does not 
mean that every garden soil needs to be acidified as Rhododendrons 
will do well at pH5 and fairly well in soils that are even less acid than 
that. However, where soil is near the neutral point, or on the alka- 
line side, it will definitely be necessary to use chemical treatments 
or to dig out the soil and replace it with peat moss, leaf mold, and
