This species of Iris is a native of Germany and Siberia, and is distinguished from those usually cultivated in our gardens by the superior height of its stems, and the narrowness of its leaves, from which last character it is often, by mistake, called graminea
, but the true graminea
is a very different plant.
The Iris sibirica
is a hardy perennial, and will thrive in almost any soil or situation, but grows most luxuriantly in a moist one, and flowers in June.
Is propagated most readily, by parting its roots in autumn.
