THE GARDENERS' CHRONICLE OF AMERICA 
143 
One of the foremost authorities on Hawthorns in the 
country has selected the following species as being fairly 
representative of their kind and worthy of being grown 
and planted extensively : 
Crataegus Arnoldiana, C. Barryana, C. colorato. C. 
compta, C. Dunbari, C. Durobrivensis, C. Ellwangeriana, 
C. ferenteria, C. foetida, C. Geneseensis, C. Laneyi, C. 
pedicillata and C. persimilis. However, the Hawthorns 
are widely distributed, and although few of the above 
species may be found in nurseries at this time it is a 
simple matter to collect small plants from the wild ; and 
those kinds growing in your vicinity are, no doubt, just 
as valuable ornamentally as any of those we have listed. 
In digging wild plants be careful to save all the roots. 
In transplanting cut back the branches severely and when 
the plants are set mulch heavily with well rotted manure. 
Hawthorns treated in this manner may make little 
growth during the first season, but they soon become 
established and grow vigorously. 
In all this use of native plants, the important thing is 
to see how nature plants and what she uses. A suc- 
cessful use of native material is a duplication of a natu- 
ral planting. "There is nothing new under the sun," and 
nature has solved every imaginable kind of planting 
problem. If you need a bank planting, a cover planting of 
deciduous or evergreen shrubs, a list of tall growing 
shrubs or small trees or medium sized shrubs for a 
shrubbery border, material for a seaside planting, vines, 
or if you contem])late an alpine garden, you can't do better 
than try to cop}- nature. 
A well planned rock garden, with its stone steps leading doivn to pool fed by a cascade tumbling down the side of the rock ivork. 
The Rock Garden in Springtime 
By J. S. Golding, New Jersey 
THINKING of rock gardens, one's thoughts dwell 
on the many beauties and wealth of coloring to 
be found among the so-called rock and Alpine 
plants with which, b}^ judicious arrangement in plant- 
ing, a beautiful picture can be presented during the 
early spring months, a most refreshing change from 
the usual displays of spring bedding. 
Many of our dwarf spring flowering plants are 
worthy of a place in any rockery and vice versa, many 
alpines grace a place of honor in the herbaceous bord- 
er. But when planted in a well-planned rock garden 
their beauty is greatly enchanced with the plants and 
flowers the pictures, and the rocks the frames, espe- 
cially so with the trailing plants when their growths 
are draped upon overhanging stones. 
At this early date when the gardener or enthusi- 
astic amateur is anticipating the glories of May and 
June, it is time to go over the plants and fill up any 
blank spaces caused by death or failure during the 
winter months. 
It is a wise plan to have a reserve of plants in cold 
frames (in pots preferred) for this operation, and 
much disappointment will be avoided if this is done, 
whether you have the highly specialized type of rock- 
ery ; where you see a miniature of the alps with the 
Matterhorn as the centerpiece ; with its Moraine for 
the more moisture loving plants, such as some of the 
varieties of campanulas, androcace, carnea, etc. ; its 
cave for filmy ferns, and waterfalls and steps leading 
to the bog and watergarden below ; or the more 
humble type built on a sloping bank or a rough stone 
retaining wall. 
The ideal rock garden should resemble the sides of 
a stone quarry with rugged stone paths to walk around
