ROCK GARDENS AND LILY POOL S 
The planning and making of a Rock Garden is the most fascinating ot all 
garden activities. One reason for this is that the Rock Garden does not have 
to be made or planted at any certain time of the year, nor does it have to be 
completed at one planting. In fact, the Rock Gardens that are giving their 
owners the most enjoyment are those that are never completely finished, but 
where there is always room to add some rare Alpine plant or a new rock of 
special formation, from time to time. Rock Gardens may vary from one which 
takes but a little corner of the Garden, to one covering the entire hillside of 
some large estate, and each be equally pleasing to its owner. There is usually 
a place for a Bird Bath or Lily Pool in nearly every Rock Garden. Water gar¬ 
dening is also very fascinating. We have a leaflet on Rock Gardens and also 
one on Lily Pools that we will be glad to send you if you would like them. 
DISTANCES FOR PLANTING. Mo$t Perennials do be$t when group¬ 
ed together, with plants 6 to 12 inches apart. If set in rows across a bed, have 
the plants about 8 inches apart in rows and the rows 12 to 15 inches apart. 
If single hedge row or border effect is wanted, either set a single or double 
row with plants 8 inches apart set alternate. Where a single clump effeft is 
wanted it is better to set three to five plants 4 to 6 inches apart, so that they 
will grow together and give the effect of one large plant. In planning where 
to set your plants, notice the heights given after name of each variety. This 
is average ultimate height of plants when in blossom. Then plan to set the 
larger growing varieties in background and the smaller sorts in front. 
TRANSPLANTING AND CULTURAL DIRECTION. Perennial 
plants should be set into the ground to same depth or ju$t a trifle deeper than 
they Stood in nurseries. Dig holes deep enough so that the roots of the plants 
can go Straight down into the soil to their full length. We advise the use of 
Peat Humus for putting in holes around bottom part of roots. A good way 
to do is to dig hole, place plant in position, throw in a handful of Peat, fill 
in earth up to within an inch or so of ground level. Then fill hole with water 
and let it soak away. Then fill in with earth to ground level, firming and 
smoothing soil with hands. If hot and dry weather conditions prevail when 
plants are set, shade for a few days until they become established. Com¬ 
plete Transplanting and Cultural diredions are sent with each shipment from 
our Nurseries.
