Rosultra

Rosultra (Edward Essig, 1929) is a remarkable Tall Bearded iris that commands attention with its vivid, mauve-infused coloring and bold garden presence. Bred from ‘Mauvine’ x ‘Diablo’, this midseason diploid variety is renowned for its homozygous purple genetics (W1 W1) and dominant non-plicata pattern, resulting in a rich, saturated bloom that stands out in any landscape. With its pedigree-worthy heritage and dramatic, color-forward appeal, Rosultra is a collector-grade addition for those seeking a memorable, field-stopping centerpiece in their iris collection. Available at Amethyst Creek Farm. Attributes: Guardian Garden, Historic Guardian Garden (GG) This cultivar is a Guardian Garden Iris. Guardian Garden irises are endangered cultivars preserved through long-term stewardship rather than routine sale. Many of these varieties have been lost to time through attrition, discontinued propagation, or the disappearance of original growers, leaving only a few known living examples in cultivation. When a Guardian Garden variety is offered, it reflects that a sustainable stock level has finally been reached within our collection; availability remains intentionally limited to protect the cultivar’s future. We encourage collectors who value historic preservation to support the continued safeguarding of rare and endangered irises by joining the Historic Iris Preservation Society.
