EXPERIMENTS WITH UDO. 15 
over such annual crops as celery or such perennial crops as asparagus. 
It has been estimated that when grown on a large scale it would 
require much less labor than celery and that it furnishes a crop from 
seed at least a year sooner than asparagus, and there may be other 
advantages which will appear during the long process of adaptation 
through which every new plant introduction must pass before it 
becomes a real factor in the diversification of our agriculture. 
Udo has already won many adherents among those who care for 
new vegetables, and, although it can not by any means be said to be 
a well-known table vegetable, it has arrived at appoint where it might 
be pushed by any careful, enterprising advertiser of fancy vegetables. 
It has been served successfully at large dinner parties in Washington 
and on the private tables of those who have -their own gardens. It is 
winning its way steadily, as evidenced by the increased call for plants 
and the fact that importations of seed from Japan have become con- 
siderable, according to recent advices from an important nursery 
firm there. 
In Europe, so far as the writer is aware, udo has not made any 
headway; but this is not to be wondered at when we consider the 
conservatism it must meet there. Mr. Philippe de Vilmorin, of the 
firm of Vilmorin- Andrieux & Cie., of Paris, admits, however, that 
udo is the one Japanese vegetable which deserves to be introduced 
into cultivation in France.
