OME of the finest aquatics will grow 
and bloom merely floating on the water 
surface, deriving nourishment from the 
air and water. In nature they drift to 
shallow water where the roots soon anchor 
and growth is very rapid. In others words, 
Floating Aquatics are always at home in 
i any pool. 
AZOLLA (Azolla caroliniana). Small crinkly, green plants resembling 
floating leaves of arborvitae. Strong sunlight turns Azolla a deep 
red. Per portion, 25c. 

DUCK WEED (Lemma minor). Appears as a series of green polka 
dots on the surface. The small roots are much appreciated by gold- 
fish. Hardy. Per portion, 25c. 
SALVINIA (Salvinia braziliensis). Dainty leaves of soft green, covered 
with a velvety nap of tiny hairs. The growth forms an attractive 
chain of these leaves which are about 144 inch in diameter. Popular as 
an aquarium plant. Per portion, 25c. 
WATER FERN (Ceratopteris thalictroides). Though an aquatic species 
of the fern family, the leaves greatly resemble garden lettuce. 
Numerous small plants spring from the edges of the leaves, gradually 
building up a floating mass of some size. The new plants may be 
detached and grow to some 6 inches in diameter before starting to 
propagate. 2 for 25c, $1.25 doz. 
SHELL FLOWER or WATER LETTUCE (Pistia stratiotes). A rosette 
of fluted blue-green velvety leaves. Grows best in a shady pool. 
50c for 3; $1.50 per doz. 

Water Lettuce, Floating Heart, Water Snowflake, 
Salvinia and Duck Weed 

WATER HYACINTH (Ejichhornia crassipes major). Shiny dark green 
leaves, the stems of which are expanded into pseudo bulbs, which 
serve as air chambers. The orchid-like flowers of lavender form a spike 
like that of the true Hyacinth. Propagation is by means of runners at 
the surface, and the growth is so rapid that navigation is hindered in 
streams in the southern states where they grow profusely. It is, per- 
haps, fortunate that the plant is destroyed by frost. The long, bushy 
roots are excellent for receiving the spawn of goldfish; therefore, the 
Water Hyacinth may be used to advantage in pools of fair size. 
2 for 25¢c; $1.25 doz. 
WATER CHESTNUT (Trapa natans). A hardy annual resembling the 
Water Fern in form but with mottled leaves and small white 
flowers. The large seeds are spiked and armoured for protection while 
wintering at the bottom of the pond. Shipped only after June first. 
25c each; 5 for $1. 
WATER SNOWFLAKE (Nymphoides indicum). A lily-like plant, the 
detachable leaves of which form new plants covered with dainty 
white flowers fringed like a giant snowflake. Shipped as floating leaf 
which soon sends down roots in shallow water. 2 for 50c; $2 per doz.
