The chief characteristics of the Darwins are the perfect cup-shape 
, of the flowers, fleshy substantial petals, tall stems and bright colors, 
NG TA L)2 ranging through all the shades of pink and red to purple. There are 
certain slaty blues and blue-violets which might almost be called a 
blue, while the black Tulip is nearly realized in some of the dark 
’ maroon varieties. There are comparatively few white or pure yellow 
CE iB 4 varieties. Most Darwins can be forced by middle of February, many 
of them even earlier, provided that they are potted as soon as re- 
ceived. 
The bulbs must be set farther apart than is the case with the early Tulips, and plenty of 
room on the benches must be given when vigorous growth begins. They should be grown 
slowly under a moderate temperature. Too high a ternperature should be avoided, or poor 
flowers result. 
Nearly all varieties, but especially the mauve colored ones, lose their true color, becom- 
ing much paler when forced. 
A star (*) preceding the name indicates that it may be 
successfully forced. The figure following indicates the relative 
time of flowering.
