The Egyptian (Perennial Tree Onion) is a perfectly 
Iiardy variety of medium quality, valued for fall plant- 
ing in the North to produce early spring bunching 
onions. (544.) 
FOREIGN TYPES 
The bulbs of Bermuda, Spanish and Italian onions are 
much larger than those of the American class. They 
also require a longer season to mature and are not so 
hardy. The flesh is more tender, and milder, but the 
bulbs do not keep as well as those of American onions. 
They are nearly always started under glass in this 
country, even in southern districts. 
Prizetaker seed was first grown in California from a 
shipment of Spanish bulbs. The variety has become very 
popular in the United States, especially for the trans- 
planting system of culture. The bulbs are very large, 
often weighing more than a pound ; bright yellow, thin 
skin; flesh white, fine-grained, mild, with a delicate 
flavor. They possess only fair keeping qualities. 
White Italian Tripoli produces very large, white, 
flattened bulbs. 
Gigantic Gibraltar and Denia produce bulbs similar 
to those of the Trizetaker, but require more time to 
mature. The) r are also milder in flavor. 
Red Bermuda, White Bermuda and Crystal Wax are 
the leading varieties of Bermuda onions.

ble to select varieties suitable to a wide range of climatic 
conditions. The most tender sorts of the foreign types, 
as the Bermuda onions, thrive in some parts of Texas, 
Florida and Southern California, and do well at the 
North when started under glass. They often, too, pro- 
duce excellent crops when sown in the open, under the 
most favorable conditions. All the American varieties
