Harlequin's Gardens is one of the best resources for Colorado-adapted plants and eco-gardening products. Our demo gardens and generous advice will help you garden sustainably. We grow many of our plants on site and manage all our plants organically. Since 1992, we have specialized in xeriscape and native plants. These plants thrive naturally in Colorado so they require less water, fertilizers and sprays. Come out for a visit; you'll enjoy it.
