Iris germanica 'Immortality'

Tall Bearded Iris

Iris germanica 'Immortality' features pure white flowers--ruffled, fragrant with excellent vigor and the best re-bloomer. Bearded Iris make wonderful cut flowers, lasting a week or more. Iris germanica is a hardy, long-lived perennial that require a minimum of maintenance. The flowers have six petals, three upright petals (called standards) and three hanging petals (called falls). A fuzzy line or beard runs down the middle of each fall.

Iris have thick, fleshy, underground stems called rhizomes that store food produced by the sword-shaped, semi-evergreen leaves. The rhizomes grow best when planted at or slightly below the soil surface with feeder roots penetrating the soil below. Each year underground offsets develop from the original rhizome. Buds produce a large fan of leaves and several flower stalks. Success with iris depends on keeping the rhizomes firm and healthy. In general, this is done by providing the rhizome good drainage while the feeder roots below remain moist but not wet.

Tall Bearded Iris Growing and Maintenance Tips:

Prefers slightly alkaline soil. Plant rhizomes near the soil surface. Planting too deep may cause rhizomes to rot. Very drought tolerant.
