sick plant. The hops are very hardy and do

For all kinds of light work, but not for a screen 
(as the foliage is too small and sparing), the

very attractive. The plant will attain a height 
of thirty feet, but as it is a thin, sparse grower,

which are cinnamon scented. It is tuberous- 
rooted and hardy in the latitude of New York 
and central Connecticut. A species that is

potato-like flavour. The vine climbs as high as 
twenty feet, but has little to recommend it outside 
of its oddity.
