CALocHORTtrs. THE ENGLISH FLOWER GARDEN. CAIOPOGON. 375 



' Lily leaf ash.' It attacks them in 

 the spring, just before the flowering 

 stalk appears. It attacks the leaf 

 tissue, and in a week entirely destroys 

 the leaf and injures the bulb. In their 

 susceptibility to the attacks of the 

 fungus Calochorti vary greatly. All 

 of the species having a single, glossy, 

 radical leaf are free from its attacks. 

 This includes all of the Star Tulips and 

 the C. nitidus group. While all of the 

 desert species, such as C. splendens, 

 C. Kennedyi, C. Palmeri, C. Gunni- 

 soni, C. Nuttalli, C. macrocarpus, and 

 C. flexuosus are subject to it to such 

 an extent as to make their successful 

 culture very near hopeless unless some 

 cure can be found for this mildew. 



" While the amateur may prefer to 

 try all sorts and get his experience for 

 himself, I believe that many growers 

 will appreciate a list of the best growers 

 among the Calochorti. For such I 

 would recommend the following : 



" In the globular - flowered Star 

 Tulips, C. albus (white), C. pulchellus 

 (yellow), and C.amoenus (rose-coloured), 

 are all thrifty and beautiful. Among 

 the open-cupped Star Tulips, C. Bent- 

 hami, in yellow, and C. Maweanus var. 

 major, are the best. There is, however, 

 a race of giant Star Tulips, sturdy 

 plants 9 inches to 16 inches high, with 

 large flowers of the same delicate 

 style as Maweanus, which, although 

 rare now, will soon quite displace the 

 smaller ones. These are C. apiculatus 

 (straw-coloured), C. Greeni (blue), and 

 C. Howelli (yellow). C. lilacinus, a 

 lavender-coloured sort, is a splendid 

 grower and very desirable. In the 

 next section, C. nitidus is a fine hardy 

 and very beautiful plant, combining 

 the attributes of Star Tulip and Mari- 

 posa. In the C. Weedi set, C. Plum- 

 mercB is best. Of the true Butterfly 

 Tulips, C. Vesta is by far the best 

 grower. It is a sort which has great 

 vitality, can be propagated very 

 rapidly by offsets (three or four a year), 

 and grows well in any well-drained 

 soil. C. venustus var. purpurescens is 

 almost as good a grower, and the two 

 are by all odds the easiest Calochorti 

 to grow. C. venustus var. citrinus, 

 in lemon, is very thrifty. That grand 

 plant C. clavatus is a fine grower. 



" I have found that by very late 

 planting I can bring sorts to flower 

 which, planted early, invariably suc- 

 cumb. I had the same experience a 

 year ago. It would seem that when 

 planted early they reach a standstill 

 period in late winter and cannot resist 



disease, while planted late they are in 

 full growth at the critical period. 



" Clearly if so much care is needed in 

 their own lovely climate, in ours it will 

 require all our care to secure them 

 perfect drainage, porous soil and 

 warmth, though no doubt some of the 

 naturally warm soils may suit them." 



C. ALBUS. A charming species more 

 easily grown than most. May be planted 

 in the open border without much fear of 

 failure. 



Calochortus fuscus. 



CALOPHACA. Pretty Pea-flowered 

 rock shrublets, C. Wolgarica, a native 

 of S. Russia, and C. grandiflora, Central 

 Asia. Plants for the rocks, banks, and 

 free soil, and, as far as I have seen 

 them, of good effect. They are allied 

 to Caragana. 



CALOPOGON. C. pulchellus is a 

 beautiful hardy Orchid suitable for 

 boggy ground, the flowers pink, i inch 

 in diameter, in clusters of two to six 

 upon a stem, beautifully bearded with 

 white, yellow, and purple hairs. Plant 

 in the rock garden, bog, or in an open 

 spot in the hardy fernery in moist, 

 peaty soil, as it is a native of wet
