IRIS

A large and remarkably diverse group of 200 to 300 species, varying in flower color and form, cultural needs, and blooming periods (although the majority flower in spring or early summer). Leaves are swordlike or grasslike. Flowers (fragrant, in many kinds) are showy and complex in structure.

Iris hybrid (Spuria)

Named for I. spuria, this group is mostly bred from I. orientalis (I. ochroleuca) and I. crocea, but species such as I. graminea and I. sintenisii figure into the dwarf spurias.  

In flower form, the beardless spurias resemble Dutch irises. Older members of this group had primarily yellow or white-and-yellow blossoms, but modern hybrids also include blue, lavender, gray, orchid, tan, bronze, brown, purple, earthy red, and near black—often with a prominent yellow spot on the falls. Flowers are held closely against 3–6-ft. stems, rising above handsome clumps of narrow dark green leaves. Flowering starts during the latter part of tall bearded bloom and continues for several weeks beyond.

Plant rhizomes in late summer or early fall in rich, neutral to slightly alkaline soil; set them 1 in. deep, 1 1/2–2 ft. apart. Plants grow well in full sun but will also take light shade for part of the day. They need ample moisture from the onset of growth through the bloom period but little moisture during summer. Divide clumps (not an easy task) infrequently; mulch clumps for winter where temperatures drop to –20°F/–29°C or lower.
