It's a joy to greet customers every day and help you find garden answers. I'm a native who started diggin' in the dirt 40 years ago, so it's fun to help you learn how to make things grow, too! I earned my Colorado Nursery Association certification in 2009, but the most valuable training has come from working alongside my colleagues – including Dennis Hill. From identifying plants & bugs to diagnosing diseases and trouble shooting garden problems... we do all we can to give you answers! At home, my hobbies are perennial and vegetable gardening, cooking and canning. My husband Rick, and my teenaged kids, Kyndall & Brandon seem to love me despite my dirt addiction. I'm their very own Mud Mama!

yrma jiminez 003 Hello. My name is Yrma. I started to work at Bookcliff Gardens in 2000. As months went by, I began seeing the many different colors and a huge variety of plants that God gave to us through this nursery. My co-workers gave me the opportunity to learn how to care for every kind of plant. Here at Bookcliff Gardens, I'm in charge of designing and planting custom pots and moss basket plantings. It is an incredible experience combining all the different colored, shapes and textures. I love taking plant cuttings and watching how they grow each day. Outside of the greenhouse I take care of my three daughters and my beautiful grand-daughter, Alexia.
