be seen in all garden waters, not thickly planted, but 

 a single specimen or group here and there. It is most 

 effective when one or a few plants are seen alone on 

 the water ; then the flowers and leaves have full room 

 to develop and float right regally; but when a dense 

 crowd of water lilies are seen together, they crowd each 

 other out. With it should be associated the yellow 

 Water Lily (Nuphar lutea), and if it can be had, the 

 smaller and rare Nuphar pumila. 



Among the Poppies, the one best worth growing 

 as a garden plant is the Welsh Poppy (Meconopsis 

 Cambrica), which grows so abundantly along the 

 road sides in the lake district. It is a perennial of 

 a fine yellow, and thrives well at the bottom of walls 

 and on stony banks. Some might care to grow 

 the large Opium Poppy (P. somniferum); its finer 

 double varieties are handsome, but these are scarcely 

 British, the plant is naturalized. The field Poppy is 

 everywhere in our corn-fields, and from it we get pretty 

 races of Poppies, double and single. The Horned Poppy 

 of our sea-shores is distinct and may be grown in 

 a garden. Corydalis bulbosa is a dwarf early flower, 

 scarcely a native, or rare ; and the yellow fumitory, 

 (Corydalis lutea) is almost wonderful in its way of 

 adorning walls and stony places, with the greatest 

 differences as to soil and moisture.
