Open Garden Days - 2021

Come visit us on the following dates to see what's blooming in our gardens. We've scheduled days throughout our bloom season so you can experience the variety and sequence of iris bloom. We will be open each of these days from 10:00 am until 4:00pm. If these days don't fit your schedule, please contact Patrick to schedule a private visit.

All Saturdays and Sundays in May
May is all about the Bearded Iris. The month starts with the Dwarf Bearded and ends at peak bloom on the glorious Tall Bearded iris. Toward the end of the month we will see the Siberians season begin. And all month different Species Iris, along with many other perennials, ephemerals and lilacs will be strutting their stuff.

All Saturdays and Sundays 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.
July 3&4 and July 10&11 - 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 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 2022 plant sales.
Be safe, sensible, and considerate of others.
Patrick & Margaret
