A Superior Rhubarb 
W. H. Henderson’s New Rhubarb 
“Giant Hybrid” —Largest stalks and leaves 
of any known variety. Possesses a rich berry 
flavor and is a great improvement over 
older varieties. Sweetest of all rhubarbs; 
requires but half the amount of sugar 
generally used in cooking other varieties. 
Stalks 1’ inch thick and 2-3 feet long. 
Divisions 50c each; 12 for $3.00. 
Wm. H. Henderson's New 
"Crimson Giant" Chard 
A cross between the sweet sugar beet and 
Swiss chard. Nothing in the garden can be 
as easily raised and no other vegetable pro¬ 
duces such a large and continuous supply of 
delicious and healthful succulent food. 
Very beautiful and highly ornamental in 
the garden. Visitors to my gardens are 
enthusiastic in praise, of its value as an 
ornamental plant. It is more delicious 
than the best garden spinach. The leaves 
are of a rich dark green color; stalks are 
richest crimson imaginable. 50c per packet; 
$2.50 an ounce. 
Note 
During the past year we have 
made e.xtensive trips throughout 
the state of California in an effort 
to personally contact our manv 
friends and customers. We shall 
endeavmr this coming year to meet 
even more of you this way. By 
these meetings it has been possible 
to perhaps offer a tew suggestions 
and to be of a little assistance with 
your garden problems. Feel free 
to write us at any time if you have 
any garden questions. 
We hold exhibits during the year 
in Southern California. This 
enables our many friends in this 
aera to see the newer creations 
first-hand. We will be glad to add 
the names of those interested to 
our mailing list to receive notices. 
These shows are held at 399 South 
Euclid Ave. in Pasadena. 
Henderson's Hybrid Giant 
Hibiscus 
{Field Jhew Ahooe) 
This new hibiscus can be grown anywhere; 
absolutely hardy. The flowers are enormous 
in size measuring from six to ten inches 
across, and when established will bloom from 
May to November. In winter the plants die, 
but the roots sprout again each spring, being 
perennial in nature. Healthy and vigorous 
and will thrive in any soil. Plant with shrub¬ 
bery. Colors range from snow white through 
all shades of pink, red orchid, scarlet and 
maroon. 
The Hibiscus offered were developed 
from a hardy longlived branch of the 
Hibiscus family. They are resistant to 
extreme cold and can be grown in the colder 
sections of the U. S. They require no winter 
protection of any kind. Only the simplest 
culture is needed. I can recommend them 
very highly for long and colorful display in 
the garden. 
The Hibiscus are not ready for plant¬ 
ing until January and will be completely 
described in our winter and spring 
catalogue. 
CULTURAL DIRECTIONS 
Plant in Jull sun—No cultivation. Cover 
eges on roots about one inch deep and stake. 
They win not sprout until weather be¬ 
comes settled and warm in spring. These 
Hibiscus require good drainage and 
moderate water supply. 
The Hibiscus has been received 
throughout the nation with un¬ 
bounded enthusiasm. They were 
written up bt" Sunset Magazine 
in December, 1937; Garden Quar¬ 
terly, 1937, Country Gentlemen 
and by many other publications 
during the past year.
