IriImmortality is a medium-sized formally shaped pure white self with light lemon yellow beards. Although it produces rather short stems with close branching, Immortality is perhaps best known as THE reblooming wonder. Its plant vigor is superb flaunting two to three stems per clump at regular bloom time and then reblooming in the late summer.
s should be planted so the tops of the rhizomes are exposed and the roots are spread out facing downward in the soil. In very light soils or in extremely hot climates, covering the rhizome with 1 inch of soil may be desirable. Firm the soil around each rhizome and then water to help settle the soil.
