| General Description |
| Iris germanica is perhaps the most familiar of its Genus. It is a herbaceous perennial with blooms on long stems. |
| Landscape |
| Makes a very reliable garden flower: use in sunny beds and borders. Good for a cut flower garden. |
| Cultivation |
| Easily grown in full sun, in moderately moist, well-drained, humusy soil. Drought tolerant. Do not plant rhizomes too deep, plant in full shade or over fertilize as these things may prevent or inhibit flowering. |
| Growth |
| Fast |
| Pests |
| Susceptible to iris borer. Diseases include: crown rot fungus, bacterial soft rot and fungal leaf spot. Mosaic virus may also be an issue: look out for blotchy flowers and leaves. |
| Leaf Description |
| Sword-shaped, linear, mostly at the base, in two ranks, about 0.5 m long. |
| Flower Description |
| Large, showy and fragrant. Six perianth segments: three purple falls (outer petals) with brown veins, white bases and yellow beards and three lilac standards (inner, upright petals). Cultivars come in a wide variety of colours. |
