The main reason R. arkansana has not been used more often as a parent is probably because of difficulty in obtaining the first cross. There are strong interspecific sterility barriers between R. arkansana and cultivated roses but a few Floribunda roses such as 'Donald Prior' will accept R. arkansana pollen. First generation hybrids are often moderately fertile and may be crossed to sister plants or back to either parent
