Japanese Roof Iris

Iris tectorum "Album"

$16.00

1 Gallon | Hardiness Zones 5-9

Scott Ogden in Garden Bulbs for the South says: "Japanese roof iris (I. tectorum) is famous in its native country as a flower for planting on sod roofs, just as housleeks are uesed on cottage roofs of France. In gardens the silky, green fans of leaves form large patches, making fine subject for the foreground of a shady border. In April the ruffled, orchidlike blooms appear among the handsome leaves. In common forms these are a rich mottled blue, with white crests. Even more lovely are the white, yellow-crested blooms of I. tectorum alba.". This is the latter form.

Light Requirements: Prefers partial shade to full sun. Iris tectorum "Album" thrives in partial shade, especially in warmer climates, but can tolerate full sun in cooler regions. It is well-suited to woodland gardens or areas with dappled sunlight. Too much direct, intense sunlight in hot climates can cause leaf scorch, so some protection is advisable.

Soil Requirements: Prefers well-draining, fertile soil. This iris grows best in rich, loamy soil with a slightly acidic to neutral pH range (6.0-7.5). It can tolerate a variety of soil types, including clay, provided there is good drainage. Incorporating organic matter, such as compost or leaf mold, improves soil structure and supports healthy growth.

Watering: Requires regular watering, especially during dry periods. Iris tectorum "Album" prefers consistently moist soil, particularly during the growing season. However, it does not tolerate waterlogged conditions, so ensuring proper drainage is essential. Mulching around the base of the plant helps retain soil moisture and regulate temperature, particularly in warmer climates.

Temperature and Humidity: Hardy in USDA zones 5-9. Iris tectorum "Album" is adaptable to a wide range of climates. It can withstand cold winters and is tolerant of occasional frost, making it suitable for both temperate and warmer regions. The plant prefers moderate humidity levels but is relatively adaptable to varying humidity conditions.

Fertilization: Apply a balanced, slow-release fertilizer in early spring to encourage healthy growth and vibrant flowering. An additional application in mid-summer can help sustain the plant during its active growing season. Organic fertilizers, such as compost or well-rotted manure, are also beneficial for maintaining soil fertility and promoting lush, healthy growth.

Pruning: Prune lightly after flowering to remove spent blooms and tidy up the plant. Removing dead or damaged leaves helps maintain the plant's appearance and prevents the spread of diseases. In late fall or early winter, trim back any remaining foliage to prepare the plant for dormancy.

Pests and Problems: Generally pest-resistant but may occasionally be affected by aphids, slugs, or fungal diseases such as leaf spot. Ensuring good air circulation around the plant and avoiding overhead watering can help prevent fungal issues. If pests or diseases are detected, treat with appropriate measures such as insecticidal soap or fungicides.
