OENOTHERA. 



nothing to interfile with the lavish and unceasing display, all summer 

 through, of its large and lovely flowers of melting delicate rich rose- 

 and-whitc on stems of 5 or 6 inches or so. 



Oe. caespitosa is also beautiful, forming tufts and mats about 

 4 inches high with blossoms of rosy pink. 



Oe. eximia or marginata is another lovely thing, but specially deli- 

 cate, running and creeping about in specially hot sandy soil, and 

 producing abundant ample blossoms of white on quite dwarf stalks. 



Oe. Fraseri, fruticosn, glabra, are all taller in growth, with hand- 

 some yellow flowers ; of which Oe. fruticosa has given two valuable 

 garden variel ies in Oe. F. Eldorado and Youngii, particularly free and 

 brilliant in the blossom, as well suited to the border as to the rock- 

 garden, if not better. 



Oe. Howardii is now the shining light of Lavauxia in America, and 

 in our gardens it often masquerades also as Oe. brachycarpa. It is a 

 neat ramifying tuft of tall, very narrow leaves, greyish-hoary at first ; 

 among which sit vast lonely Evening Primroses of deep, rich yellow, 

 on stems of 3 or 4 inches. It is a pretty thing, and might be associated 

 perhaps with Campanula alpestris, did it not usually come too late into 

 the field to make a contrast. 



Oe. macrocarpa or missouriensis is an especially fine species for the 

 rock-garden, for, though the stems are tall, they do not stand up, 

 but stagger and lie down over the faces of rocks, in such a way as to 

 give the fullest value to the plant's especially enormous cups of pure 

 clear citron-yellow all through the later summer. It is also a good 

 hearty perennial, asking only for ordinary rich loam in the sun. 



Oe. mexicana has a name for pinkness, but is rather to be distrusted. 



Oe. ovata is greatly advertised. It makes neat and rather leafy 

 rosettes on the ground, and then, among their leaves produces all 

 through the summer a quantity of little yellow Evening Primroses not 

 quite large enough to redeem the wecdish look of the rosette, though in 

 themselves both bright and abundant, it is true, on any sunny slope. 



Oe. pumila has the same stature and the same flowers of yellow. 



Oe. riparia is advertised. There are far too many obscure plants 

 that go to make up the large and misty personality that is meant by 

 almost all the foregoing names. 



Oe. semUata grows 6 inches high, still with little yellow Evening 

 Primr< 



speciosa is taller at times than even the rose-pink Oe. pallida 

 its relative; thi notably beautiful, but much the finest form is 



lhat called Oe. sp. rosea, with flowers of more brilliant rose, and a more 

 modest habit. This, if suited, in a hot garden and sandy hot soil,
