Oenothera 



Ueiioilieras or eveiiinsr primroses have the distitiitioii 

 of lieing ue-ariy all natives of our hemisphere. We know 

 most of the uprijrht biisliy growing species to be very 

 valuable border plants on account of the vivid yellow 

 hues of their large clusters of flowers. In the northera 

 pari of the New England States 1 used tlie frutieosa 

 varieties, such as Eldorado, Fra,seri, Pilgrimi and, par- 

 ticularly the very popular Oenotliera frutieosa Youngi 

 for June effects. Blended with the blue of delphiniums 

 and the white of the Madonna lilies the clear golden 

 hues of solid masses of evening |>rimroses outcla.ss in 

 purity and strength by far those of Coreopsis grandi- 

 flora. In order to oiitain tlie desired ])erfection we 

 should give our plantations an oiien sunny ex|)osure, in 

 a rather light but otherwise rich soil. In addition I 

 advise dividing and replanting every other sesi-son. The 

 ground remanured each time and, during the summer 

 months, sufficiently irrigated, we are bound to have 

 vigorous growing and freely branching plants of which 

 we may expect that alnmdance of blossoms necessary 

 for a strong color efiEect. Xeglected evening primroses 

 soon turn out to be an eye-sore in any garden. 



Perfectly hardy, the frutieosa species attain an aver- 

 age height of 14 to 2 feel. As a recent novelty, origi- 

 nating with Henrv A. Dreer, T mention Oenothera fnit- 

 ico.sa pallida, producing very attractive flowers of a 

 creamy white color. I>ower in growth — alwut 1 to H 



fuel in iieight — are the two species Oenotliera caespitosa 

 with large pure white flowers turning to rose, and 

 Oenothera speciosa, producing pure white blossoms 

 throughout the entire season. Both prove excellent sub- 

 jects for liei-baceous borders. The flowers of the new 

 variety — spwiosa rosea, mea-suring about 3 inches across 

 aiv of a delicate jiink color. 



In conclusion 1 l)eg to call special attention to the 

 two specnes of eree|)ing growth, treasured among our 

 showiest inmates of rock gardens. Oenothera Harvadi 

 from Nevada is distinguishable by its grayish whit- 

 hirsute long narrow foliage and beautiful deep yellow 

 flowers. Oenothera missouriensis depicted by our illus- 

 tration enjoys the greatest popularity of all the evening 

 primroses. It is the largest flowering sitecies, of clear 

 sulphur-yellow: in bloom from early in July until late 

 in Septendier. Both prefer the high sunny location and 

 endure |)r(ilonged jreriods of draught without serious in- 

 jury, for tJieir rootstocks penetrate dov\'ndeep into the 

 ground. Contr-arj' to the frutieosa and speciosa types 

 tliey should be leit undisturbcnl as long as possible. 



On the whole, evening primroses merit more attention 

 and garden space than they have so far received. Under 

 proper cultural care they prove a highly effec;tive mater- 

 ial, indispensable for floral midsummer and late spring 

 displays within the precincts of American gardens.
