The genus Iris includes ≈300 species widely distributed in the temperate regions of the Northern Hemisphere, and many of them are attractive ornamentals that are largely used as groundcover plants for gardening and landscaping (Boltenkov et al., 2020). However, the leaves of most Iris species are high and prone to lodging easily, thus affecting their ornamental appearance. Therefore, dwarf Iris plants are desirable and popular. Because dwarf cultivars of some Iris species are relatively rare (Huang et al., 2003), there is a strong demand for dwarfing breeding of Iris. ‘Mini Fen’ as an Iris sanguinea cultivar is a dwarf plant type.
I. sanguinea is an important perennial ornamental plant (Yang et al., 2017), and it is widely used as cut flowers and in landscaping of Northeast China because of its unique, large, brightly colored flowers and strong tolerance to drought, pollution, and coldness (Dong et al., 2019; Song et al., 2014). I. sanguinea breeding mainly focuses on unique flower colors and shape, thus leading to the development and release of many new cultivars such as Beautiful Lotus (Wang et al., 2016), Forest Fairy (Kuwantai et al., 2018), Zi Meiren (Chen et al., 2019), NEFU-1 (Qi et al., 2020), and Flower Angel (Fan et al., 2021). In 2016, a new dwarf I. sanguinea cultivar was selected from the hybrids of I. sanguinea and Iris sanguinea f. albiflora and registered as Mini Fen in 2021. ‘Mini Fen’ has a unique dwarf plant type and dark pink [Royal Horticultural Society (RHS) N81A] flowers, which are different from its parents and all the ornamental cultivars of I. sanguinea.
