Abstract

<p>The natural habitats of Veronica ornata Monjuschko (Plantaginaceae), an endangered perennial plant endemic to Japan, were investigated on the Oki Islands of Japan. Seedlings obtained from wild plants were characterized as ornamental plant resources. The morphological diversity of the plant form, flower characteristics, and flowering periods were observed in this species distributed in various environmental habitats on the Oki Islands. The varietal characteristics of this species make them applicable wide-ranging utilization for pot and cut flowers and bedding plants materials. Besides the predominant purplish-blue flower color, white and purple flower plants were found, and they are considered potential breeding resources to develop new flower color varieties. It was also suggested that flowering plants could be produced that bloom for long periods by combining varied flowering periods. The regional genetic resource, V. ornata, is proposed as a new ornamental plant native to Japan. Breeding new cultivars and development of a production system based on their characteristics comprise the next step.</p>
