New Open Garden Schedule - 2024

Cascadia Iris Gardens will now be open to the public Friday through Sunday beginning May 17th through the end of July. Come visit us to see what's blooming in our display and production beds. You can experience the variety and sequence of iris bloom throughout the season. Also note that we have large collections of peonies, lilacs, spring ephemerals and other interesting perennials and trees. We will be open from 10:00am until 4:00pm. 
What to see in April 
Our first Miniature Dwarf Bearded Iris (MDB) will open very near April 1st, as will several of our small woodland iris species, trilliums and erythroniums. Mid-month will see the Standard Dwarf Bearded Iris begin to bloom. Aril and Arilbred iris will join in. The month will end with the Median Iris just showing first blossoms. Our 80 or so varieties of lilacs will begin blooming late in the month and are a sight and smell to behold.
What to see in May
May is all about the Bearded Iris. The month starts with the Dwarf Bearded and ends at peak bloom for the glorious Tall Bearded iris. Toward the end of the month we will see the Siberian iris season begin. And all month different Species Iris, along with many other perennials and ephemerals will be on display. Over 100 varieties of peonies will begin blooming mid-month and are worth a visit by themselves!

What to see in June 
June is peak month at CIG. Our Tall Bearded and Siberian Iris will still be in bloom. The Sino-Siberians, Spurias and early Japanese will also be showing off. Peonies, perennials... the list is seemingly endless. The month will end with a few of our reblooming iris starting to do their thing.
What to see in July - July is all about the Japanese Iris. We have the largest collection in the USA along with Patrick's Seedlings. You might even find the odd Bearded or Siberian irises reblooming.
We truly hope you can join us. Our new greenhouse is full of potted iris, peonies, lilacs and other choice perennials. As we progress through the season, new plants will be added as we work our way through iris shipments, transplanting and preparing for 2023 plant sales.
Please be safe, sensible, and considerate of others.
