BORDER PLANTS 63 



while of blues there are Beauty, Excelsior, Grand Maitre, 

 and General Gordon. Marie Stuart is a good new white. 

 But the older sorts will not be despised while such charm- 

 ing things as Marie, peacock-blue and yellow ; Belle 

 Chinoise, yellow ; King of the Blues, blue ; Cajanus, tall 

 yellow ; Blanche Superbe, dwarf white ; and Thunder- 

 bolt, bronze, are available. These June-blooming Irises 

 are useful for clumps in the border and they are almost 

 ridiculously cheap. One hardly dare write of the new 

 hybrid Irises, for they are dear. Regelio-Cyclus Mars, 

 Psyche, Charon, Hecate, and Isis are remarkable hybrids. 

 These are kinds for the specialist, who has long ago 

 exhausted the interest in well-known species like alata, 

 aurea, ochroleuca, stylosa, Persica, orchioides, sind- 

 jarensis, sisyrinchium, susiana, florentina, laevigata, and 

 the great Flags. He will harass the few firms who deal 

 in rare novelties until he acquires them. Warleyensis, 

 azure, and Willmottiana, lavender, mottled with white, 

 are novelties the price of which is not altogether pro- 

 hibitive, although they are not cheap enough to be planted 

 in quantity by everybody. The hybrids between pallida 

 and iberica are beautiful plants ; of these Sir Dighton 

 Probyn and Sir Trevor Lawrence may be named ; but 

 many others are in existence, the fruit of the work of the 

 late Sir Michael Foster. Another set of hybrids, called 

 Intermediates, are available for specialists ; they have 

 Germanica blood, and may be described as small Flag 

 Irises ; Dorothea, Freya, Halfdan, Helge, Ingeborg and 

 Ivorine well represent them. Mrs. Alan Gray is a pretty 

 lavender hybrid between Cengialti and Queen of May. 



KNIPHOFIA (TRITOMA, TORCH LILY, RED-HOT 

 POKER). The great value of these plants lies in their 

 giving beautiful groups of colour at the end of summer.
