Hybrids
Rosa persica can hybridise with other rose species, and these hybrids have in the past been known as the hybrid genus ×Hulthemosa. However, the yellow colour in cultivated roses is not generally derived from this species, but from other yellow-flowered wild roses. One of the few ×Hulthemosa cultivars commercially available is 'Alissar, Princess of Phoenicia' (also known as 'Harsidon').Similar species
