Conifers were also planted in groups of 6 to 75 trees, some as 
units and others in combinations. The unit groups have made 
better growth, and make a better appearance. The following list 
shows the species planted:

All of the species of Picea are doing well, and a few of the trees of 
Pinus ponderosa and P. sylvestris are growing, but only one P. 
montana mughus and no P. contorta latifolia survived. 
ORNAMENTAL SHRUBBERY 
This group was by far the largest in both numbers and species. 
The plantings on the whole were successful, making a good growth 
from the start, but considerable replanting was necessary during 
the first three years. 
Notes and observations are made on the usefulness and ornamental 
value of the different species and varieties. The following have 
proved the hardiest and most successful as landscape subjects:

HARDY PERENNIALS 
The only hardy perennial that has proved entirely dependable 
and successful is the peony. A large bed planted to German iris 
winterkilled the first year, as did also a number of perennials grown 
from seed planted in a long border. The failure was probably due 
as much to drought as to winterkilling, however, and this group of 
landscape-gardening plants is to be tested more thoroughly.
