Siberian Iris have no summer dormant sea-

ponds although they will thrive in most any 
part of the garden. A well watered soil rich 
in humus and slightly acid with full sun or 
light shade is recommended. A _ profusion 
of bloom on tall graceful stems emerging from 
grass-like foliage makes the Siberian Iris espe- 
cially valuable for your garden.
