Iris pseudata 'Roryu'
Roryu Iris
Iris pseudata 'Roryu' is a captivating Japanese hybrid, blooming in early to mid-summer with distinct, brassy yellow flowers adorned by intricate red veining. The central "signals" of each petal are highlighted with yellow and framed by fine red markings resembling delicate eyelashes, adding a refined detail to the blossoms. These open, wide blooms bring a dynamic presence to any garden, especially near ponds or in damp borders where the bold color can truly shine.

Design tip
The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. It takes sun or light shade, which makes it useful along the changing light of a bed edge or a partly shaded border.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
