Tucson Botanical Gardens was established in the 1970s on the former homestead of a local family, and even though the facility encompasses a relatively few acres, it continues to grow and draw more attention and larger crowds.

Gardens executive director Michelle Conklin says among projects under way or in the planning stages are a summer camp and gardens for children, a recently completed new entrance and an effort to enclose a reception area for events.

In addition to its list of more than a dozen individual gardens, the facility has four gardens on display created by local landscape architects or designers in what's been called a "Grow Down" competition.

The goal was to create a comfortable living and garden area on a compact space of just 15 feet by 22 feet.
