How to Build a Rock Garden 
Select a gentle slope. Use the largest 
boulders possible, placing the bigger stones 
at the base, the strata all running the 
same. They should appear naturally 
placed. A few large rocks rather than 
many small ones are preferable. 
In the pockets between boulders there 
should be a rich, porous, moisture-holding 
soil at least two feet deep. Provide mois¬ 
ture in abundance. 
Most entrancing groups of plants for 
Rock Gardens are low growing, brilliant¬ 
ly flowering, rather heavily foliaged 
Perennials. For interesting results the 
year round, include some dwarf Ever¬ 
greens like Abelias, Azaleas, Daphne, Juni¬ 
pers, Retinosporas, Yucca, Yews, Pachy- 
sandra, Cotoneasters, for their touch of 
evergreen foliage, stability and the floral 
beauty of the blooming kind. 
Low Annuals should always be added 
for continuous bloom through the Sum¬ 
mer.

Barr’s Perennials Are Fully Developed, Strong Plants 
The stock offered in Barr’s List of Hardy Perennials is either fully-developed 2-year, field-grown 
plants or in certain kinds which transplant better from pots are pot-grown. We aim to have you obtain 
the very best results, and ask that you do not confuse these strong, large plants with small, seedling 
plants available at less cost but far less satisfactory in results. It always pays to buy the best obtainable, 
especially in living things like plants where weakness in stock either means the loss of your entire invest¬ 
ment or a long time coaxing them along to realize any satisfactory results at all. 
Varieties Designated “R” in Descriptions are Favored for Rock Gardens
