maritimun has finer flowers. They like a light soil, and 

 plenty of water while in growth. 



TIGRIDIAS 



Tigridias are among the most brilliant of summer 

 bulbous plants, but though they have been established 

 in some southern gardens, they are not generally hardy 

 in Britain. The greater number in cultivation are 

 varieties of T. Pavonia (syn. grandiflora) and these 

 are very beautiful, their only fault being the short time 

 the flowers last. The type has scarlet petals and a 

 yellow, crimson-spotted cup, but there are a number of 

 varieties ranging from white, through almost rose to 

 lilac, pale yellow and orange yellow. Immaculata alba, 

 Immaculata lutea, and the new "Nankin" are among 

 the latest introduced. Van Houttei (Hydrotaenia Van 

 Houttei) has brown and yellow flowers and is rather 

 more delicate, and should have a frame or greenhouse. 

 Violacea and Pringlei should have similar treatment. 

 All may be potted and grown in a greenhouse if desired. 

 Plant in April or May. 



ZEPHYRANTHES 



Reference has already been made to Z. Candida among 

 hardy bulbs. A few others may now be mentioned 

 for frame or cold greenhouse cultivation. These are 

 strangely neglected by amateurs, as their pretty crocus- 

 like flowers are exquisitely beautiful when open. 

 Generally speaking, I should recommend their being 

 grown in pots in the greenhouse, where they can have 

 a sunny position near the glass. The best of those 

 known for the frame or cold greenhouse are Andersoni, 

 which grows about four inches high, and has yellow or 

 coppery flowers about May ; Atamasco, white, tinted 

 pink, grows about nine inches high, and blooms about
