By Fi Hybrids, we mean a variety whose seeds are produced by systematic crossing of individual 
flowers of two especially selected inbred parents. The key to finer Fi Hybrids, of course, lies in the 
development in these parents of superior characteristics which they in turn impart to the resulting 
Fi Hybrid. 
Our own plant breeding staff, as well as breeders throughout the world, are working very inten- 
sively to bring the advantages of Fi Hybrids to more and more flowers. Not only is there GREATER 
INHERENT VIGOR AND PRODUCTIVENESS in Fi Hybrids, but UNIFORMITY is assured by 
trueness of the parent lines. 
Our new CRUSADER PETUNIA is the latest addition to our Fi Hybrid varieties. Its vigor and 
uniformity of growth, combined with a semi-dwarf habit, makes it an excellent bedding or pot variety. 
Incidentally, have you tried F: Hybrid vegetables? Our Ball Giant Hybrid Tomato is the newest 
of our Fi Hybrid Tomatoes and should be excellent for home garden plant sales. Try it.
