of the larger-flowered summer bloomers. One 
has white flowers, the other blue. The mere 
fact that they can be had in flower before June, 
is sufficient justification for their addition to our 
popular hardy vines for trellis or pergola. Al- 
though the individual flowers are smaller, these 
two species, flowering profusely, make a brave 
show of bloom. 
The white-flowered species (C. montana) is 
the best for garden effect. Its pure white flowers 
are borne in great profusion the first week in May, 
and are the early analogues of those of the ubiqui- 
tous Japan clematis of August. A little winter 
protection is necessary near New York, but with 
the best shelter it may be relied upon to attain 
a height of twenty feet. As it branches freely, 
it will quickly cover a large trellis, when once it 
is established. The pale-blue flowers of C. 
cerulea appear two or three weeks later. This 
is a dwarf vine, the maximum height being 
about ten feet. The plant is of interest, however, 
in being one of the parents of the hybrid varieties 
of clematis grown by florists for winter forcing. 
Clematis can be transplanted, but should 
not be disturbed unless absolutely necessary, 
as it takes some time in getting reéstablished. 
When planting, be very careful to give the
