Perhaps the most beautiful and the most resistant to virus infection of the 'leichtlinii' group is the Edgar Kline clone, 'unicolor'. We don't know if this was an unspotted seedling selected from seed grown 'var. maximowiczii' or from wild collected stock as there is little information. Used extensively in breeding at the old Oregon Bulb Farm, 'var. unicolor' was instrumental in producing the first of the "brush mark" type lilies.
