SUMMER BULLETIN, 1921. 



NEW AND RARE EVERGREENS. Ready August and September. 



Abies Delavayi. 



Chinese Spruces at our Cape Cod Nursery. 



Picea asperata var. ponderosa. 



NEW FIRS FROM CHINA. 



Introduced by the Arnold Arboretum. 



Abies Delavayi. This is one of the handsomest of the Silver Fir 

 family. It is also one of the hardiest known in China. Mr. E. H. 

 Wilson tells us it is known in China by the name Lien-sha, meaning 

 Cold Fir, in allusion to the fact that the tree grows in cold regions. 



Its upright growth and rich deep green foliage make it rival in 

 appearance the Yew trees of Europe, and we predict that for lands- 

 cape purposes this Fir will be used to produce the Yew effects here. 

 $5.00 each. 



Abies recurvata. This Fir is of pyramidal habit. The rich deep 

 green foliage resembles that of Abies Delavayi, but is strongly re- 

 curved, which gives the tree a distinct and pleasing appearance. Mr. 

 Wilson writes: "In all respects this species is one of the most desirable 

 of the family; and it was well worth a long journey to introduce it 

 into cultivation." It has proved perfectly hardy and like A. Delavayi 

 will be a valuable addition to our trees for landscape planting. $5.00 

 each. 



NEW CHINESE SPRUCES. 



Introduced by the Arnold Arboretum. 



Picea asperata. A quadrangular-leaved Spruce from northwestern 

 China. Some of the trees are very glaucous in appearance, hence 

 the colloquial name. Yun Sha (Cloudy Fir). Old trees are very 

 spire-like in outline. All the varieties of P. asperata are of dense 

 growth, and the purplish coloring of the young foliage makes them 

 strikingly beautiful in the early Summer. 



Picea asperata var. notabilis. This variety differs from the pre- 

 ceding, chiefly in the cones, the scales of which are rhombic-ovate in 

 outline. 



Picea asperata var. ponderosa. This handsome variety is remark- 

 able for its large cones. 



Picea Balfouriana. One of the tallest of the Chinese Spruces. 



Picea montigena. The short, stout bristly leaves are of shining 

 green and more or less glaucescent. 



Picea retroflexa. Glaucous foliage in somewhat spiral arrangement. 

 Very interesting. 



Strong Plants of the above varieties, $3.00 each. Collection 0^6 

 varieties, $15.00. Larger Plants, $5.00 each. Collection of 6 

 varieties, $25.00. 



Picea albertiana var. couica. 



PICEA albertiana var. eonica. (Illustrated' above.) A beautiful, pyramidal evergreen tree of slender proportions. Its density of short 

 silvery green needles gives it the appearance of a Retinospora, rather than a tree; a rare and valuable plant. 



Plants 4 to 6 inches, $1.00 each. Plants 10 to 12 inches, $3.50 each.
