130 BULBOUS PLANTS. 



be put in the ground after danger from frost is past, and at later inter- 

 vale to give a succession of flowers. The finest bulbs are supplied so 

 cheaply by American growers, that it does not pay to propagate in 

 small quantities. 



RICHARDIA >ETHIOPICA (Calla) which are out of service should 

 have the water gradually withheld from them, and as the foliage dies 

 down turn the pots on their sides and leave them in this position until 

 the time arrives for starting into growth in Autumn. The pots should 

 not be put in a place were the sun will have full play on them. For in- 

 creasing the stock of the yellow varieties they should be grown all 

 Summer; plant them outside in rich, well-drained situations where they 

 can be watered abundantly when occasion requires it. All of them are 

 easily raised from seeds. In Winter they need a minimum temperature 

 of 60 degrees. By the middle of September the largest sizes of R. aethi- 

 opica should be in 6 and 7-inch pots and placed in an open frame. Have 

 the sash handy so that they may be protected during wet weather. 

 With a good watering at first they won't need much moisture till good 

 roots are formed. At least one third of rotted cow manure should be 

 in the soil. 



TRILLIUM About a dozen species of these beautiful and interesting 

 native plants are in cultivation. T. grandiflorum is the one most com- 

 monly grown, owing to its very large white flowers. Its culture is of 

 the simplest description, requiring a half-shaded position with abun- 

 dance of vegetable humus in the soil. It is sometimes grown in pots for 

 early forcing, for which purpose it is well adapted. The rhizomes should 

 be potted as soon as the plants are at rest, late in Summer, and plunged 

 in a cool frame until wanted. With very little heat they will flower 

 several weeks in advance of their usual time. 



VALLOTA PURPUREA A very useful plant, either for the greenhouse 

 3r the window garden, but not of much service to the florist, as it 

 flowers at a period when the demand for cut flowers is not very great. 

 As the bulbs will last in the same pots for several years, the drainage 

 should be carefully arranged, and the soil mixed with crushed bone. 

 During growth occasional waterings with manure should be given. 

 The flowers are reddish scarlet, several in an umbel; in appearance some- 

 what like those of an Amaryllis. The foliage is evergreen, but during 

 the resting season the supply of water should be curtailed. 



Propagation The Vallota has a very curious method of making 

 young plants which I do not remember to have seen described any- 

 where. These young plants are produced to such an extent that the 

 process tends to curtail the flowering propensities of the larger bulbs if 

 attention be not given in the matter of removing them. In course of 

 time they form two colonies, one on each side of the parent bulb. The 

 bases of the leaves forming the bulb have each a small bud-like growth
