Ornamental Conifers

Abies pungens glauca 



Eetinospora pisifera has many sports. The best are: 

 p. auroa, wliich is identical with the type but yellow 

 colored; p. aureo variegata, a shorter growing vellow 

 variegated form ; p. stricta lutesecns,. of erect habit and 

 yellowish in color; jx nana, a very dwarf, round-grow- 

 ing little plant. 



Eetinospora plumosa is a different type of pisifera, 

 with much finer growth and needles very open. The 

 different forms of it are : Aurea, of a nice 3'eUow color ; 

 pi. lutescens or argentea, dwarfer in growth, more 

 compact, broader than it is tall, of a pale yellowish 

 color; pi. albo-spica, thickly spotted with white, but 

 ,when in good growing condition this variety often re- 

 verts to the t\-]3e. 



Filifera, another type of pisifera, grows to a certain 

 size and makes nice bushy little trees with long cord- 

 like pendulous shoots, good to isolate on the lawn. E. 

 til. aurea, the same, bright yellow-colored; fil. aureo- 

 variegata, with yellow variegated shoots; fil. gracilis is 

 of dwarf habit, more compact and thinner, more nu- 

 merous shoots of yellowish color. 



Eetinospora squarrosa, which is a sport from pisifera, 

 has its needles wide open of a bluish color, and is very 

 effective on the lawn, where it needs, like pisifera, a 

 sheltered place, being a little tender. Squarrosa has to 

 be clipped ; it dies out in the centre when of a certain 

 age and looks bare. Sq. Veitchii, a thick compact dwarf 

 form, has the foliage more heather-like; sq. decussata, 

 the same as type, smaller and more compact; sq. sul- 

 furea is of a nice yellowish color in spring while grow- 

 ing; seems to be hardier than the others. 



E. Sanderi has very heather-like foliage of blue color; 

 dwarf in habit, round in form ; seems to be a sport from 

 squarrosa, too. 



Abies concolor 



Nearly all the forms of Eetinospora pisifera make 

 good sized trees, good to isolate on the lawn as well 

 as in big beds. 



TTTUYA 



The Tliuyas are divided into Thuya, Thuyopsis and 

 Biota. I'huya occidcntalis, the common arbor-vitae, is 

 of pyramidal outline.' It does not grow to a big size; 

 it likes to grow near the water, brooks or lakes, where 

 it retains its foliage and freshness much better than in 

 drj' soil, .especially near the seashore, where the foliage 

 turns yellow, burns and falls off. It is a tree which 

 withstands the severest vnnter when near the water; 

 in the Adirondacks and in Canada in the swamps at 40 

 degrees below zero you can see them as green as grass, 

 while here some die at 15 degrees. It is a well-known 

 fact that conifers and evergreens in general bear severe 

 cold when surrounded l\y dampness, but not loy stagnant 

 water. 



There are a great many forms of arbor vitae in cul- 

 tivation; a few of the most distinct are as fellows: 

 Thuya oecidentalis, compacta pyramidalis, fastigiata 

 oolunmaris and a few others are narrow, compact, erect 

 growing trees ; Bodmerii has the shoots flat lycopodium- 

 ]ike; plicata has them twisted; both are narrow-, erect 

 in gi-owth. Buchananii is broadly pyramidal in form 

 with erect cord-like twigs of a grayish-green color. Pen- 

 dula has the branches pendant. Aurea G. Peabody, 

 Cloth of Gold, var. Waxen, Wareana lutea, Ver 

 vaeneana, Ellwangerana aurea, all grow to a good size, 

 p-\Tamidal, more or less compact, and lighter or darker 

 yellow in color. Alba Queen Victoria and argentea 

 Columbia take in the fall a creamy-white color at the 

 lop of the growing shoots. Douglasii and Spaethii are 

 two curious forms : the young shoots are long and cord- 

 like, the leaves open only the second year and are
