damp, boggy ground, and in shaded spots will continue 

 to flower for a couple of months after the border Forget- 

 me-nots have ceased to bloom. 



Nierembergia rivularis. — A dwarf plant of trailing 

 habit, bearing cream-white flowers two inches across. 

 It is best suited by a somewhat shaded position and 

 moist soil. 



Parnassia palustris. — Grass of Parnassus. An attrac- 

 tive native plant, bearing in the summer white, green- 

 veined flowers on upright stems six inches in height. 

 America supplies us with three others that may be 

 associated with our native species, namely P. asarifolia 

 with larger leaves and flowers, and P. caroliniana and 

 P.jimbriata whose white blossoms have fringed petals. 



Pinguicula grandiflora. — This dwarf plant, which is the 

 most handsome of its race, is found wild in certain dis- 

 tricts in Ireland. It bears violet-blue flowers about an 

 inch in length. It requires a soil very porous in nature 

 and constantly moist, and thrives best in a shady spot. 

 P. lusitanica, also found in Ireland, bears yellow flowers 

 and P. vallisneriafolia, from the mountains of Spain, has 

 blossoms of a soft lilac-purple. The same treatment 

 suits all. 



Pyrola rotundifolia. — A plant about nine inches in 

 height occasionally found wild in this country, and bear- 

 ing racemes of pure white, fragrant flowers on erect 

 stems. Each flower is half an inch across, and twenty 

 blooms are often borne on a stem. It will succeed in 

 moist soil in a shady spot. The variety P. r. arenaria 

 grows on sandy sea - shores, and should have a more 

 open position in the garden than the last-named. 



Ranunculus ample xicaulis. — A pretty white-flowered 

 plant growing to a height of a foot, which thrives 

 in moderately moist, porous soil such as that to be 

 found in the dryer portions of the bog garden. 



Shortia galacifolia. — A very beautiful little spring
