Know before you buy
Unlike traditional irises that bloom only once in spring, 'Immortality' produces an initial flush of flowers in late spring and continues to bloom intermittently through the summer and into fall. To maximize this, you should deadhead the spent stalks to encourage the plant to direct its energy into new flower production.
Yes, this variety is well-suited for containers, provided the pot has excellent drainage. Ensure the container is large enough to accommodate the rhizomatous root system and place it in a location that receives full sun throughout the day.
This plant requires full sun, which means at least six to eight hours of direct sunlight daily. If planted in partial shade, the stems may become leggy and the plant will likely produce fewer blooms.
The most critical factor is soil drainage; these irises will not thrive in heavy, waterlogged soil, which can cause the rhizomes to rot. If your soil is heavy clay, amend it with organic matter or sand to improve drainage, or plant them in raised beds.
When planting, ensure the top of the rhizome is just barely covered with soil or even slightly exposed to the sun. Planting them too deeply can prevent the plant from blooming and may lead to rot.
Yes, 'Immortality' is known for having a sweet, distinct fragrance. While it is not overpowering, you will notice the scent when planted near walkways, patios, or seating areas.
