Summary
Iris ruthenica, commonly known as Ever Blooming Iris, is an evergreen perennial herb that is native to the grasslands and forest margins of Asia and Siberia and Romania. It features a rhizomatous growth habit with grass-like leaves and a thick stem. The plant typically grows to a height of 3–20 cm (1–8 inches). Iris ruthenica is known for its violet or bluish lavender flowers, which are marked with violet veining and bloom in spring or early to mid-summer, depending on the region. The flowers are fragrant, usually solitary, but occasionally a second flower may appear. Despite its common name, it may not flower prolifically in certain regions such as the UK.
This iris is valued for its low-growing, clump-forming habit and its suitability for rock gardens or as a border frontage plant. It can also be grown in sinks, troughs, or on dry peat banks. While it tolerates semi-shade, it prefers full sun to thrive. Iris ruthenica requires fertile, well-drained soil that remains moist. It is hardy to USDA Zone 2 or 3, indicating its resilience in cold climates. Propagation can be achieved through division or by seed, with seeds sown in autumn and rhizomes divided in early spring. Care should be taken when moving the plant, as it is best transplanted during its active growth period in spring and summer. Potential issues include susceptibility to iris borer and root rot in overly wet conditions.CC BY-SA 4.0
