Exjoy HALLAWELL'S 
LOVELY MAY FLOWERING TULIPS 
Each year our Holland growers send us new tulip originations for plant- 
ing in our San Francisco trial gardens. We observe them for a season 
and compare the quality with other varieties before listing them in our 
catalog. By this method over the years we have accumulated the finest 
varieties of each color class and eliminated many near color duplicates, 
so that you may order your tulips with the assurance that each variety 
represents the height of perfection in its color class. 
Our Mayflowering tulips comprise varieties from two groups, the Darwins 
and the Cottage. Darwins- are a vigorous race of self-colored flowers dis- 
tinguished by their tall, stout stems and their cup shape. Cottage tulips 
have chiefly oblong-shaped flowers with narrow base, although some 
strongly resemble Darwins. Wle have combined the two groups to elimi- 
nate color duplications, to reduce the number of varieties offered and 
thus enable us to be more selective in the choice of varieties we list in 
our catalog. 
When a new tulip under trial at our gardens shows itself to be better 
than any other of its color we add it to the list, superseding the older 
type. Thus our list results from annual checks and observations of tulips 
in actual growing and flowering for this area. We keep our list up to 
date by replacing the other varieties with new and better ones when they 
are available. 
BORE HINTS FOR PLANTING TULIPS 
Plant 6 to 7 inches deep, 4 to 5 inches apart. Groups of 50 to 100 of one 
variety will all bloom at the same time and make a beautiful mass dis- 
play. Use a background of related colors for heightening the effect. 
For best results, remove all the soil, a foot deep, scatter bone meal, cover 
it one inch, set the bulbs, replace the soil.

19th AVENUE AT SLOAT BOULEVARD 
The annual Spring Bulb Show at our BLUE GLASS NURSERY GAR- 
DENS is a blaze of color from February to May. Group plantings of tulips, 
daffodils and other spring flowering bulbs make a fine display and provide 
an opportunity to make a choice of varieties for your next season’s plant- 
ing. 

Following the bulb show we have a grand display of fuchsias, pelar- 
goniums and geraniums in great variety. The gardens are open to visitors 
on Sundays and week days except Tuesdays during the summer season. 
Visitors are always welcome.
