the Cape of Good Hope, resembles a gladiolus but 
is taller; it is very fine for the garden. The yel- 
low calla (Richardia Elliottiana), which masses 
well in appropriate positions; the Chilian lily (4/- 
strémeria chilensis), which is not hardy without

pink and white bloom is superb when planted out

sirable addition to the garden that the extra care is 
of negligible consideration. There is a wide range 
of shades from white to red and a variety in form 
and size of the flowers. 
Other autumn-blooming bulbs are numerous, but 
while they are usually hardy few of them are for 
the many. The saffron crocus (C. sativus) and
