FLOATING PLANTS 
S OME of the finest aquatics will grow and 
bloom merely floating on the water sur¬ 
face, deriving nourishment from the air 
and water. In nature they drift to shallow wa¬ 
ter where the roots soon anchor and growth is 
very rapid. In other words, Floating Aquatics 
are always at home in 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 (Lemna minor). Appears as a series of green polka dots 
on the surface. The small roots are much appreciated by goldfish. 
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 % 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 Snow Flake and 
Artificial Alligator 
WATER HYACINTH (Eichhornia 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, perhaps, 
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 advan¬ 
tage in pools of fair size. 2 for 25c; $1.25 
doz.

ROCK PLANTS 
Rock plants thrive under adverse conditions and' are attractively used as 
a border edging for the pool itself or for a perennial bed around it. The 
pool may be edged with rough stone and any crevices that will hold a 
handful of soil will accommodate one or more interesting rock plants.
