Harold Barker stands in his extensive garden of hundreds of spring bulbs which has provided passersby with a scene of beauty for more than 20 years. Currently, the 300-foot-long garden sports tulips and daffodils, which when finished, will give way to the blooms of many kinds of perennials. The colorful scene along the road at 3108 Klingler is one of several large gardens at the Barker home. Mr. Barker also collects and sells catalogs of many kinds, including garden catalogs, some of which date from the 1880s.
