Iris tectorum seed
LATIN NAME: Iris tectorum
COMMON NAME: Roof Iris
The roof iris is the purple-blue flag of the old roofs, and the crested, three-lobed flowers open above the fan of the leaves. The tufted, rhizomatous, perennial plant carries the fans of the narrow, sword-shaped, green leaves and the fine, blue-violet flowers with the yellow-crested falls and the white-tipped standards through the late spring, one of the fine, bold sights of the old garden. The rhizomes have a long record in the old practice of the warm East, and the plant is a fine, historic presence of the courtyard. It is a plant of the open, sunny to partly shaded, moist, well-drained ground.
Scientific Research & Plant Biotechnology
The roof iris is a historic subject of the plant science, and the crested flowers keep showing up in the work on the iris group. The way the crested falls hold the fine yellow marks of the flowers has been studied closely, and it keeps appearing in the studies of the iris group, the crested irises and the members of the iris family. The fans of the narrow leaves and the rhizomatous habit have also made it a fine study plant, and the roof iris is a regular subject of the work on the purple-blue flags of the cool world.
Ecological & Economic Value & Wide Applications
The roof iris is a fine, bold plant of the courtyard and the old garden. The fine, blue-violet flowers with the yellow-crested falls and the white-tipped standards open through the late spring, one of the fine, bold sights of the season, and the fans of the sword-shaped leaves hold the neat, green clump through the year, while the rhizomes have a long record in the old practice of the warm East. The plant is one of the fine choices for the courtyard, the roof bed and the mixed border, and it has been written up in the horticultural and the botanical papers for the crested flowers and the long record of use. It is a fine, bold plant of the open, sunny to partly shaded, moist, well-drained garden.
Give the rhizomes a sunny, well-drained spot and divide the clumps every few years for the fresh fans.
To grow the roof iris from seed, press the large, round seeds a couple of centimetres down in a tray of fine seed compost, keep the tray in a bright, open spot and water gently, then set the young plants out in the open ground. The seedlings come up in their own good time and grow on steadily. With the sun or the light shade and the moist, well-drained ground, the crested flowers will open through the late spring.
