Brevoortia Ida Maia. A beautiful Californian bulbous plant, better 

 known perhaps as Brodicea coccinea. It has drooping umbels of deep-red 

 and bright-green tubular flowers. Best increased by offsets if obtainable. 

 Seeds produce flowering plants in three or four years. 



Brodisea. A genus containing several species of pretty bulbous plants, 

 mostly North American, and fairly easy to grow. There is a fair trade 

 in the bulbs (or conns) in the autumn, when they are planted in well- 

 drained soil. One of the best-known species is B. unifiora (formerly 

 better known under the names of Milla and Triteleia), which has white 

 flowers. Other kinds are: calif ornica, rose purple; capitata, lilac or 

 violet, with a white variety; congesta, deep violet; Douglasi, bright blue; 

 gracilis, bright yellow ; grandiflora, violet blue ; Hendersoni, salmon 

 yellow striped with purple; Howelli, porcelain white, striped blue, and 

 its fine variety lilacina] hyacinthina, purple; Orcutti, lilac; Purdyi, rose 

 purple; &c. 



Bulbocodium vernum. A pretty Alpine Crocus-like plant of the lily 

 family, having violet or rose-purple funnel-shaped flowers in January, not 

 more than 6 in. above the ground. It is easily grown in good garden 

 soil, and is often planted in grass land. The trade is done in the bulbs 

 (corms) in early autumn. 



Buphthalmum. The two best species are B. salicifolium and B. 

 speciosum or cordifolium, both 3-5 ft. high, with golden-yellow or orange 

 flower heads 3-5 in. across. They grow in any garden soil, and are 

 effective on the banks of lakes, streams, &c. They are easily increased 

 by seeds and division. The trade is chiefly in the roots, but the plants 

 are good for cut bloom. 



Calamintha. This genus has a few good rock plants, the best being 

 alpina, 6 in., purple; glabeUa, 3 in., lilac purple; and grandiflora, 9 in., 

 purple. They flourish in ordinary soil, and are increased by seeds and 

 division. 



Calandrinia speciosa. This grows 1-1 J ft. high, with spoon-shaped 

 leaves and deep purple-crimson flowers from June to September. It is 

 usually treated as a hardy annual. Other kinds are G. discolor, 1 ft., rose 

 red; G. oppositifolia, tuberous rooted, with white or bluish flowers; and 

 G. umbellata, 6 in. high, with brilliant magenta-crimson flowers. 



Calendula officinalis. This is the common British yellow Marigold 

 an annual that is capable of looking after itself. The choicer garden 

 varieties, like Meteor, Orange Cockade, Orange King, &c., having splendid 

 heads of rich orange red, are largely grown, the trade consisting in the 

 seeds and young plants in spring. 



Callirhoe. Ornamental Mallow-like plants, easily raised from seeds, 

 but not very well known commercially. The best kinds are involucrata, 

 with trailing stems, 6-9 ft. long, and crimson flowers; digitata, 2-3 ft. 

 high, purple; G. Papaver, bright purple red; alcceoides, 2 ft., lilac purple; 

 lineariloba, 9 in., crimson and white; and G. pedata, cherry red.
