Uses and Benefits: Iris 'Immortality' is ideal for adding brightness and fragrance to mixed borders, cottage gardens, or formal plantings. Its reblooming nature extends the iris season, providing a second burst of beauty just as summer wanes. A classic companion for pastel plantings and a standout among white perennials, it also makes a graceful cut flower.

Companion Plants: Pair Iris 'Immortality' with Achillea 'Peter Cottontail' for a soft, textural echo. Add Lavandula 'Ellagance Snow' to enhance fragrance and attract pollinators. Finish the grouping with Festuca 'Beyond Blue', whose cool tones provide contrast and year-round structure.

Care Instructions: Plant in full sun with sharp drainage. Ensure rhizomes are exposed at the soil surface. Water regularly during dry spells, especially in late summer to support fall rebloom. Cut back old foliage in fall and divide every 3–4 years for best performance.

History: Iris 'Immortality' was introduced by Lloyd Zurbrigg in 1982 and became one of the first widely grown reblooming white tall bearded irises. It remains a garden favourite for its pure colour, fragrance, and repeat-flowering habit.

Final Thoughts: Pure and perennial in every sense, Iris 'Immortality' offers grace in spring and again in fall—a rare and welcome gift that brings renewal to the garden twice each year.
