Welcome to Long's Gardens

Welcome to Long’s Gardens! We are a third generation, family owned and operated iris farm in the middle of Boulder, Colorado. We were founded in 1905 by J.D.Long. Today the business is carried on by Catherine Long Gates, grand-daughter of J.D., and her husband, Dennis Gates.

For more on our history, see About us. We specialize in bearded iris, which we sell both as dig it yourself and by mail order catalog. Operating an agricultural enterprise in the middle of a city makes for some interesting challenges, but also provides an opportunity for people to slow down, take a break, and relax (take a virtual tour at Beyond the Bloom). Come see and smell the iris and enjoy a bit of historical Boulder. We’re open to the public when the iris are in bloom, May through early June. Please check back often for updates.

We are now open for the 2019 season through June 9, from 9:00 to 5:00 every day.


If you would like a copy of this year's catalog when it comes out, please email or write us with your name and address.


In August 2017, Long's Gardens was recognized as a Colorado Centennial Farm - one that has been in the same family for over 100 years. We went to the State Fair in Pueblo and were honored along with 37 other farms and ranches in Colorado. We have been in our current location for 103 years in 2019 and in business for 114 years.

Unpretentious, a Standard Dwarf Bearded iris, the day after it was coated with snow last week.


   Today is cold with rain and drizzle. The fields are muddy. It would be best to delay your visit until later this week.

   We have MDB, SDB and IB iris in bloom. The Tall Bearded have not yet opened. They should be opening near the end of the month.
