When we moved into this house almost 17years ago, the yard had traditional flowers like peonies and iris. The peonies have almost been shaded out over the years, but the iris are still going strong. Most likely they are Iris pallida dalmatica: tall, pale lavender, tough as nails with a Concord grape fragrance. I brought Iris pumila 'Cherry Garden' with me from our former garden. Over the years I've acquired countless other Iris until I now have Iris of all types blooming from the end of the snow until mid-June. That was never a conscious plan but it's certainly worked out well.
My Iris photo parade (below) includes a Rosebud matchbox for scale in a number of the pictures. It's 1 and 1/2" tall (3.8 cm) x 2" long (5.1 cm) and 1/4" (.06 cm) deep.

Reticulated Iris: Iris reticulata 'Harmony' (above)

Lake Iris: Iris lacustris 'Alba' is found along the gravel shores of the Great Lakes and blooms earlier than the Crested Iris in my garden.

Lake Iris: Iris lacustris 'Alba' is about half the height of the crested Iris.

Dwarf Crested Iris: Iris cristata 'Navy Blue Gem' is a darker form of the popular plant.

Dwarf Crested Iris: Iris cristata of unknown origin. I bought a couple of plants at the WHPS sale and also at the West Side Garden Club sale — perhaps from the same garden.

Dwarf Crested Iris: Iris cristata of unknown origin. This photo gives you a sense of what a great ground cover this plant is.
Iris gracilipes: a Japanese woodland plant. Slightly taller than Iris cristata.

Iris gracilipes: This was the first season for this plant. Notice the delicate stems and buds. I am totally in love with this little gem! It will develop into a rounded clump, a bit like a daylily.

Dwarf bearded Iris: Unknown Iris pumila from the garden of my former co-worker and garden mentor, Doris Lang.

Tall German or Bearded Iris: I call this Iris pallida dalmatica "Smithy," in honor of the Don Smith family who built our house and put in the original trees and perennials.

Tall German or Bearded Iris: These are pretty much pest-free, very tall (38" / 96.5 cm) and never flop over — even after strong winds and rain.

Tall German or Bearded Iris: This view shows you the irises in place. The area long the dry stream where these irises bloom is dry, compacted soil and they love it.

Dwarf bearded Iris: Iris pumila 'Cherry Garden.'

Dwarf bearded Iris: I've been growing 'Cherry Garden' for just over 20 years and still love its velvety falls and rich saturated color.

Bearded Iris: Iris germanica 'El Dorado' is bi-color and tends to flop a bit but the flowers are so stunning that I put up with that little fault.

Bearded Iris: 'El Dorado' is described as an "unusual elongated open flower in which the tips of lthe standards never touch." It's about 35" (88.9 cm) tall.

Water Iris: This unknown Iris laevigata arrived in a pot of supposedly blue plants. Either that, or it is the result of the blue water Iris crossing with Iris laevigata 'Snowdrift' while I wasn't looking.

Water Iris: This view shows two varieties of Iris laevigata that self-seeded in the pebble beach at the edge of the pond. The rest of these Iris grow in the bog where they were originally planted a dozen years ago.
Not pictured: Siberian Iris (Iris sibirica) and Japanese Iris (Iris ensata).
