A New Pot Plant Variety Bred by Interspecific Crossing between Tecoma stans (L.) H. B. K. and T. garrocha Hieron

A new cultivar of Tecoma, originating in South America, was selected from among the interspecific hybrid progenies between T. stans and T. garrocha. The selected interspecific hybrid has an orange corolla, intermediate in color and size between T. stans (orange-yellow) and T. garrocha (orange-red). Although T. stans required uniconazole treatment to induce blossom formation, the selected interspecific hybrid did not. The newly selected hybrid is expected to be of horticultural value and interest in the Japanese flower markets.
