OXYGENATING PLANTS For Pools 
Sagitlaria Sinensis 
Vallisneria 
• Keep the Water Pure and Clear 
• Provide Spawning Space for Fish 
• Shelter and Protect Baby Fish 
Every pool needs oxygenating plants to keep the water crystal 
clear and pure. These plants grow under water just like plants you 
see growing naturally in ponds and lakes. They absorb impurities 
from the water and liberate oxygen, which action clarifies the water 
and helps to prevent the growth of Algae that turn the water green. 
Oxygenating plants are indispensable when fish are present, as they 
set up a balanced or natural condition of the water. They also will 
assist materially in raising a hatch of baby fishes, as the young fish 
find much needed shelter and protection among their foliage. 
HOW TO PLANT OXYGENATING PLANTS IN POOLS 
Use small boxes or 5-inch pots and plant the oxygenating plants 
in soil. Leave the soil level an inch below the top of the box or pot 
and fill up the remaining space with sand. This prevents muddying 
up the water when the plants are placed in the pool. Place the box 
or pot directly on the bottom of the pool in between the lilies. A 5- 
inch pot is large enough to accommodate about three plants. Oxyge¬ 
nating plants should be planted in containers by 'hemse.ves and should 
never be planted in the same containers with lilies.

"Gardens of the Nations" Lily Pool 
Enthusiastically Viewed by Hundreds 
“Last season when we first discussed having a lily pool on the 
eleventh floor Gardens of the Nations I was frankly a little 
timid about it as I feared that to plant such a pool around May 
15th—as we were obliged to do—the effect throughout the entire 
summer would not be very satisfactory, and since we get so many 
visitors from practically every State in the Union, obviously we 
want to show them some good gardens whatever they may be. 
“I am amazed, however, at what can be done with a lily pool 
in one season. Practically ever since June 1st we have had some 
interesting plants in flower and even today, almost October 1st, 
there are a dozen or more of your hybrid water lilies in bloom. 
The gold fish too which you supplied seem to be very happy, with 
quite some increases and no losses. 
“I am very glad now that we made this change and I can 
truthfully say that this little aquati i garden has been one of the 
most interesting spots this summer. The public at large ex¬ 
pressed their appreciation to our hostesses and incidentally kept 
them busy answering all kinds of questions about your plants.” 
Very truly yours, A. M. Van den Hoek, Horticultural Director, 
Rockefeller Center, Inc., New York City.
