pensate for the greenhouse treatment they require. All 

 require a very strong, rich soil, and the Coburgias do 

 well in the open border, but flower better if grown in 

 pots, as in the border they are more disposed to make 

 offsets than flowers. If grown in pots, which is the best 

 way of treating them, they should be plunged in the 

 open border until the leaves are fully grown, when they 

 may be brought into the greenhouse to develop their 

 flowers. 



S. coccineum.— Scarlet. Native of Peruvian Andes. 



S. incarnatum (Coburgia). — A very large bulb, and 

 requires planting from five to six inches deep. Flowers 

 cup-shaped, of a bright crimson color, with green spots 

 on each petal. Keep perfectly dry during winter. 



S. i. fulvum. — A more delicate variety, with light 

 orange flowers. It succeeds best in the open border, 

 and the bulbs are stored like the Gladiolus during win- 

 ter (Page 115). 



STERNBERGIA. 



See Page 22. 



STRUMARIA. 



A small genus of Cape bulbs allied to Nerine (Page 

 21), and requiring to be grown in the same manner. The 

 flowers are red, white or pink. They are of dwarf habit, 

 and thrive with ordinary greenhouse treatment. 



TIGRIDIA. 



Tiger Floiver or Tiger Iris. 



These singular Mexican bulbs have no equal for gar- 

 den display, when we consider their ease of culture, the 

 length of time they are in flower, their magnificent col- 

 ors and singular forms. Their remarkable flowers are 

 of but short duration, never lasting more than a day, 

 but are produced in such successive abundance as to 

 compensate for this defect; one plant will continue
