Dahlia Blue Book for 1950

# Dahlia Blue Book 1950

This is a nurseryman's catalog from Rocky River Dahlia Gardens in Rocky River, Ohio, dated 1950. The opening presents a commercial grower's account of their operations and dahlia showmanship over the past season, detailing attendance at major exhibitions across Michigan, Ohio, Illinois, and Georgia.

The bulk of the catalog comprises detailed ordering and propagation information. It explains three primary product types: green plants (dahlia cuttings rooted in pots), rooted cuttings (unrooted but callused), and pot roots (miniature clumps grown in three-inch pots), along with field-grown root divisions and fall-dug clump sales. The catalog includes specifications for size classification (exhibition, cut-flower, miniature, pompon), flower form type (cactus, formal decorative, peony, single, etc.), and color categories for retail ordering.

Featured introductions include B & B, a ten-inch lavender formal decorative with Certificate of Merit recognition, and Clariam Gold, a ten-inch straight cactus in deep golden yellow also receiving awards in trade publications.
