210 AQUATIC PLANTS 



Small Hardys 

 Pygmaea (white), Pygmaea helvola (yellow), Laydeckeri lilacea 

 (rosy lilac), Laydeckeri rosea (pink to red). 



OTHER POND PLANTS 



Lotuses (Nelumbiums). Album grandiflorum (white), Luteum 

 (yellow), Speciosum (rose), Pekinensis (red). 



The culture of Nelumbiums requires more root-space than for 

 water lilies. Planted in a shallow pond where they have plenty of 

 space for the strong roots to branch out and travel, they prosper 

 amazingly. They are hardy over winter, and if it is desired to con- 

 iine them to a certain space or locality they should be boarded in or 

 otherwise divided from the rest of the pond. The roots go several 

 feet deep. The Lotus is one of the most beautiful of all decorative 

 plants. Its magnificent leaves and flowers swaying majestically in 

 the summer breezes convince us that this plant well deserves the 

 prominent place it has been accorded in the literary classics through- 

 out histor3^ 



Water Snowflake is one of the most charming of the small float- 

 ing aquatics. White, star-like flowers of 1-inch diameter are freely 

 borne above the water. Parent plant should be rooted in soil near 

 surface. 



Bog Plants. Among the best of the bog and pond plants are Varie- 

 gated Sweet Flag, Cape Pond AVeed, Marsh Marigold, Umbrella Plant, 

 Cyperus papyrus, Water Arum, Pickerel AVeed, Sagittaria japonica, 

 Sagittaria montevidiensis, and Lizard's Tail. 



ENEMIES OF AQUATIC PLANTS 



The most serious enemies are muskrats. These eat the roots of 

 several hs-vAy aquatics, particularly over the winter season. They are 

 partial to the roots of the small yellow water lily, Pygmaea helvola. 



A leaf-cutting worm (Hydrocainpa), sometimes becomes quite a 

 nuisance. It cuts a piece from the edge and, laying it on the leaf, 

 attaches the two together and uses the two pieces as a cocoon. Loose

bits of water lily leaves, Sagittaria, etc., observed floating around 

 will, if pried apart, often be found to contain this white worm. The 

 illustration is life size. They should be hunted out and destroyed.
