From Wikipedia on Irises

The genus is widely distributed throughout the north temperate zone. Their habitats are varied, ranging from cold and montane regions to the grassy slopes, meadowlands and riverbanks of Europe, the Middle East and northern Africa, Asia and across North America. Irises are perennial herbs, growing from creeping rhizomes(rhizomatous irises) or, in drier climates, from bulbs(bulbous irises).

They have long, erect flowering stems which may be simple or branched, solid or hollow, and flattened or have a circular cross-section. The rhizomatous species usually have 3–10 basal sword-shaped leaves growing in dense clumps. The bulbous species have cylindrical, basal leaves.

The inflorescences are fan-shaped and contain one or more symmetrical six-lobed flowers. These grow on a pedicel or lack a footstalk. The three sepals, which are spreading or droop downwards, are referred to as “falls”. They expand from their narrow base, which in some of the rhizomatous irises has a “beard” (a tuft of short upright extensions growing in its midline), into a broader expanded portion (“limb”), often adorned with veining, lines or dots. The three, sometimes reduced, petals stand upright, partly behind the sepal bases. They are called “standards”. Some smaller iris species have all six lobes pointing straight outwards, but generally limb and standards differ markedly in appearance. They are united at their base into a floral tube that lies above the ovary (known as an inferior ovary). The styles divide towards the apex into petaloid branches; this is significant in pollination.

Iris Danfordiae—from Kemper Center for Home Gardening

[Naturalized wildflower in central Florida.]

Common Name: iris
Zone: 5 to 9
Plant Type: Bulb
Family: Iridaceae
Missouri Native: No
Native Range: Turkey
Height: 0.25 to 0.5 feet
Spread: to 0.25 feet
Bloom Time: March – April Bloom Data
Bloom Color: Primrose yellow (with tiny dark spots on the falls)
Sun: Full sun to part shade
Water: Medium
Maintenance: Low

[Naturalizes easily in woodlands, etc. If one chooses to provide some care to them, it would be minimal.] Easily grown in average, medium, well-drained soil in full sun to part shade. Soil needs to stay relatively dry in summer in order for the bulbs to set buds for the following year. Plant bulbs 3-4” deep and space 3-4” apart in fall. Bulbs tend to separate into offsets or bulblets after bloom (particularly when planted shallowly), with each new bulblet requiring several years to mature.

Noteworthy Characteristics:

This is a yellow-flowered reticulata iris. It is a low-growing bulbous iris that blooms in March to early April in the St. Louis area, at about the same time as snowdrops (Galanthus), glory-of-the-snow (Chionodoxa) and the early crocuses. Bright primrose-yellow, 2” diameter flowers with tiny brown or black spots on the falls appear on naked stems (scapes) growing 4” tall. Narrow, grass-like leaves elongate to 12” after bloom, but eventually disappear by late spring as the plants go dormant. Flowers have a sweet fragrance.

Other interesting facts I have gathered up:

Dwarf Yellow Iris

4" tall. Early spring blooming. This little beauty is renowned for its ability to naturalize and form colorful mats of bright yellow flowers and is extremely fragrant. Very cold hardy

These are among the genera with the earliest flowering spring bulbs. These can spread and be naturalized in a lawn or garden bed. These bulbs can be planted in annual beds, and then the annuals can be planted among them. The bulb leaves should be left to die down naturally to build up the bulbs for next season.
