TULIPS 
THE CLASSIFICATION OF TULIPS 
As the Tulip has been a very popular garden flower and in large commercial 
demand for over 250 years, there has naturally been a great production of varieties. 
The number of varieties listed in Holland catalogues, all told, approaches the 2,500 
mark. Their classification is therefore complicated, and more or less artificial. 
A committee of the Royal Horticultural Society of England in 1917 drafted a 
classification, which is briefly explained in the descriptions given in our catalogue, 
in the belief that tulip growers will be interested and helped to a better under¬ 
standing of the characteristics of varieties. According to the R.H.S. classification, 
Tulips are divided into three classes: 
I.—Native, or natural-growing species. II.—Early Flowering. III.—Late, or 
May Flowering. 
The native species of Tulips are those original native species growing in 
Europe, Asia, England, etc. It is from these that the numerous horticultural 
varieties have been derived. 
The Early Flowering Tulips comprise: (1) Single Early Tulips; (2) Double 
Early Tulips; (3) Due Von Tholl Tulips. 
The late or May Flowering Tulips comprise groups known as: (1) Darwins; 
(2) Breeders; (3) Cottage Tulips; (4) Parrots; (5) Rembrandts; (6) Byblooms; 
(7) Bizarres; (8) Late Double Tulips; (9) Lily Flowered Tulips; (10) Mendel 
Tulips; (11) Triumph Tulips. 
Darwin Tulips 
The culture of these Late or May Flowering Tulips has developed in recent 
years into a fad amongst flower growers, as their beauties and merits have 
become recognized. They were 
named in 1889 after the great 
English naturalist, Charles Dar¬ 
win. Some years previous they 
had been originated by an un¬ 
known amateur in the north of 
France. 
The bloom is borne on strong, 
stately stems 18 to 30 inches in 
length. Their range of colors 
embraces almost every conceiv¬ 
able tint of rose, heliotrope, 
claret, maroon, crimson and rich 
shades of purple approaching a 
black and within the past four 
years yellow and white Darwins 
have been developed also. The 
flowers of Darwin Tulips are 
large, globular and of heavy tex¬ 
ture. As cut flowers they are 
much used and very satisfactory. 
They are most valuable for per¬ 
manent planting in borders and 
amongst shrubbery. They show 
best in clusters, and will continue 
to bloom for years. 
From the many hundreds of 
varieties on the market, we list 
only the following varieties. We
