Catherine Long Gates will lead the tour. Catherine is the third generation manager of this family business that is celebrating its 103rd year of business in Boulder. The firm has specialized in growing iris plants for the last 50 years. This tour will give you a look back at some of the earlier endeavors Ð the old bins and jars that stored the flower and vegetable seeds sold during the first 60 years of the business, the wooden drawers in the "bulbhouse" for storing gladiolas and the "modern" tractors purchased after WWII to replace the garden horse.

All of the tours are free and open to the public. Meet Catherine at the gardens, 3240 Broadway, at 5:30 p.m. June 11.
