230 Trees for Shade and Ornament 
and where picturesqueness is desired in bold, wild lansdcape, rather 
than on cultivated lawns, also perhaps for formal avenues and accent 
trees in large parks, although in later life they lose their formality. 
The one mostly planted is — 
L. decidua Mill. (43) (Europea), from Europe: a medium-sized moun- 
tain tree, apt to suffer in the lowlands unless compensated in the soil for 
our drouthy atmosphere, although otherwise not selective as to soil; it 
will grow in the most barren, rocky sites, for which it is indeed best 
fitted. It is easily transplanted, but should be planted early in 
spring, as it buds out very early.

L. laricina Koch. (Americana) (44), the native, northeastern Amer-

the European, being a tree of the swamp; less dense and compact in 
growth, less graceful and symmetrical in form, with shorter foliage. 
It is adaptive to wet places, and is best used in open groups. Unfor-

The other American larches, L. Lyallit Parl. (45), a small tree from 
timber-line of the northern Rocky Mountains, and L. occidentalis Nutt
