Harmony is a diminutive and very early lavender-blue iris that grows from a bulb. It blooms with snowdrops and winter wolf’s bane, popping out of the ground in spring as soon as frosts become irregular and the ground warms a bit. Harmony’s display is brief, but if the bulbs are planted thickly and in quantity, they put on a memorable show. Give them a location in full sun where the soil is very well-drained.
Note: Iris Harmony is resistant to deer, but rodents such as voles and gophers may eat the bulbs.

Iris reticulata requires well-drained soil and full sun, and it likes to be dry in summer. After bloom, the narrow, grasslike foliage begins to elongate, eventually standing 12–14 inches tall. It collapses and disappears by early summer.
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
