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 2018 season and will be open everyday from April 28 through June10 from 9:00 to 5:00


It's a great time to come see the shorter iris. The dwarf iris and Intermediate Bearded iris are both in bloom. There are a few Tall Bearded iris in bloom now, with more stalks coming up. They should be more after a day or two of sun.


The last few days of cool, rainy weather has delayed the opening of the Tall Bearded iris. There are a few open now, but the forecast sunny and warm weather should speed the opening of more. If you come in the next day or two, you will want to wear appropriate footwear for wet conditions in the fields.


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 102 years in 2018 and in business for 113 years.


Rare Edition an Intermediate Bearded iris is now in bloom and available to dig. Come dig this and other beauties for some early season color for your garden!
