This is the
largest group of bulbous iris. The Dutch and
Spanish types were bred from I. xiphium
while the English iris come from the
species, I. xiphoides. Dutch iris
with their delicate flowers bloom the
earliest followed by the fragrant flowers of
the Spanish iris and the last to bloom are
the English irises noted for their larger
flowers with erect standards.
The Dutch and
Spanish iris are tender and often need to be
replaced frequently in temperate zones.
English iris are a bit tougher and will
survive mild winters but they are
susceptible to a virus.
