SPANISH AND DUTCH IRISES 
We have put these two groups together as the 
only important difference from a gardening stand¬ 
point is that the Spanish come into bloom about 
two weeks later than the Dutch. The Spanish are 
somewhat taller and more slender than the Dutch. 
These are excellent garden flowers coming 
into bloom just after the tulips. They have be¬ 
come extremely popular for cutting as they are 
very graceful and long lasting. By proper choice 
of varieties one can have these irises in bloom 
over a period of two months or more. 
Iris bulbs should be planted about 4 inches 
deep in well drained soil. October planting is 
probably best in most parts of the country. Where 
the winters are severe the beds should be mulched 
after the freezing begins.
