CULTURAL DIRECTIONS 
Plant in jull sun—No cultivation. Cover 
eyes on roots about one inch deep and stake. 
They will not sprout until weather be¬ 
comes settled and warm in spring. These 
Hibiscus require good drainage and 
moderate water supply. 
During the past year we have made 
extensive trips throughout the state of 
California in an effort to personally contact 
our many friends and customers. We shall 
endeavor this coming year to meet even 
more of you this way. By these meetings 
it has been possible to perhaps offer a few 
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 area 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. 
The Hibiscus has been received 
throughout the nation with un¬ 
bounded enthusiasm. They were 
written up by Sunset Magazine in 
December, 1936; Garden Quarterly, 
1936 and by many other publica¬ 
tions during the past year. 
Wm. H. Henderson's New Giant Hybrid Hibiscus 
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. All plants bloom well the first year planted. 
Testimonial from a satisfied customer: “Just a line to tell you of the Hibiscus 
root I purchased from you this Spring. To date, Sept. 1st, I have picked 215 blooms from 
the bush. Each bloom measured from 8 to 10 inches in diameter. The root was planted 
March 1st. — Mrs. E. T. S.”
