Vallota purpurea (Scarborough Lily) somewhat resembles a 

 Hippeastrum, and should receive similar treatment. Raise from 

 offsets, and grow in sandy loam, peat, and leaf-soil. Keep dry in 

 the cool pit in winter, grow warm in summer after flowering, and 

 then partially dry off in early autumn. The flowers are scarlet. 



Veltheimia viridifolia is a useful bulb, flowering in spring. 

 Propagate by offsets. At the time of potting in autumn grow in 

 loam, leaf-soil, and sand, in a cool pit or in frames. Ripen 

 after flowering, keeping in pots, and starting again in February. 



Ornamental Foliage Plants.

The effect of these plants, however, and of all the flowering 

 plants, greatly depends on the taste exercised in their arrangement. 

 They should be scattered thinly amongst the groups of flowering 

 plants on the stages, using one species to a group. If the
