that it falls over rather than stands up straight. These two hybrids 
were also considered to be not quite hardy enough for the Dutch 
climate and the stock that had been accumulated was destroyed. 
In the meantime, however, samples of all the bulbous iris produced 
by our firm had been sent to Messrs. Lowe & Shawyer, owners of 
large greenhouses near London, England. After they had been 
forced, it at once became apparent that in WeEpGEwoop we had 
raised a forcing iris of the very highest quality. The little sample 
was carefully grown to maturity, the bulbs saved and from these 
few a new stock built up, one which, by now, covers many hundreds 
of acres. 
Blues Are Favorites 
While WepcGEwoop is and for many years will be the leading 
variety for greenhouse use, the florist and the public, as well, have 
been rather surprised that it should be the only iris now available 
in quantity and are now demanding other colors. Confronted with 
this demand, the growers have again turned to those iris which by 
virtue of their resistance to virus diseases and other cultural 
troubles offered the opportunity for mass production with its en- 
suing lower production cost. Without any doubt this was found in 
the old variety Imperator. Darker blue than WepcGEwoop, later 
and with a slightly smaller flower, it is a perfect flower both for 
cutting and for garden decoration. It is generally considered to be 
hardier than WeEpcEWwoop and can be produced commercially in 
regions where WrEDGEWoop does not thrive. 
With two good blues, one light, early blue and the other dark 
and late, there still remained a need for a good medium-late, light 
blue of good size. This gap has now been filled quite adequately 
by the beautiful BLur Horizon, an introduction of our firm of 
some ten years ago. Strangely enough, with adequate stocks of these 
three good blues, the demand for other colors has been less active. 
Our records show that even with plenty of other colors available, 
blue iris outsell the yellows and whites almost ten to one. ‘This 
percentage differs somewhat according to the region. San Francisco, 
for instance, has always insisted on receiving a larger proportion of 
yellow iris. Los Angeles florists seem to be more partial to whites. 
The yellow iris are dominated by the variety YELLOW QUEEN. 
Again an introduction of our firm, this one is very old and dates 
back to long before World War I. It is most prolific and will flower
