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.

Our iris bloom is over, but we will still be available by appointment. Please call or email ahead to make arrangements. You may also order plants for later summer shipment or pickup.

   We have extended our order deadline through August 15.


   Our you-dig field still has a great selection of plants that are identified with photo signs.

     Order plants: Check out our catalog listing if you'd like to get your iris plants later in July & August.


Add some zest to your garden with Citrus Sorbet,available in our digging field.

 We have photo signs in the digging field so, even with the bloom over, you can see what the flower should look like.
