PERENNIALS 
THE LIST — We have carefully selected the plants for this list, and have ex¬ 
cluded all which have no place in the well-considered garden. To be sure all 
of these perennials are not equally valuable, and some have serious faults, 
but are included because of their adaptability to some special situation. There 
is no such thing as a perfect plant: blue flax is possessed of delicacy, grace, 
color, and a long blooming season, and it is free from disease and insect pests, 
but mature plants will not stand transplanting and it is short lived, though it 
compensates somewhat for these faults by self-sowing easily. The net result 
is one of the most satisfactory plants for the average garden. 
In addition to the species and varieties listed in this catalogue, we have at the 
nursery many others, of which we have a small stock only; if you do not find 
what you wish on this list, ask us about it, for we may have it in stock. 
DESCRIPTIONS — In a catalogue of this size it is impossible to give a complete 
picture of each plant, its appearance, habits, and preferences, but we have 
attempted to give here what appear to us to be the salient points. We have had 
to omit much valuable information, but if you want to know the foliage type of 
Caryopteris, whether Geums like sun, or anything else about perennials, we 
will be glad to assist you to the best of our knowledge and experience. 
COLOR — Word descriptions of color are admittedly inaccurate because people 
do not see alike: what is purple to one may be blue or red to another. If 
you are trying to work out a color scheme and want to know whether the pink 
listed is one which will ‘click’'’ with rose or fight with it, we will give you our 
dpinion on the matter. But as it is a controversial subject, we would much 
prefer that you would come to see the flowers in bloom and decide for yourself. 
DATES — Flowering dates vary, of course, from season to season and place to 
place, and we only approximate them in this list. We do however keep a 
record of the blooming dates of all plants in the nursery, so if you live in the 
vicinity of Philadelphia and want to know whether cowslips and blue phlox 
can be depended upon to bloom together, we will be glad to give you the benefit 
of our experience on that point, or any other comparative blooming dates. 
HEIGHT — The numbers preceeding the common names of each plant give the 
approximate height of the plant at blooming time. It is hardly necessary to 
point out that this will vary, as much as several feet in some instances, accord¬ 
ing to the soil, the amount of feeding, water, and the care which the plants 
receive. 
TRANSPLANTING TIME — A good general rule is to transplant fall-blooming 
perennials in the spring and spring-blooming ones in the fall, but this is not 
always convenient. Almost everything can be transplanted in very early 
spring, as soon as it is possible to get on the ground. All spring transplanting 
of perennials should be completed before May, and fall planting should be 
done early enough for the roots to get established before the ground freezes: 
the last of September is ideal for most plants. At any time of year the weather 
must be taken into consideration: avoid transplanting in a high wind or under 
a blazing sun; a dull cloudy day before a rain is the best time.
