Iris chrysographes 'Black Form' (Ships in Spring)

Black Iris

Iris chrysographes ‘Black Form’ is a striking perennial bearing deep purple, nearly black blossoms. Each petal displays a delicate yellow ribbon, creating a dramatic contrast. More refined than bearded irises, its elegant flowers sway atop slender stems above sword-like foliage. Blooming from early to mid-summer, this iris thrives in full sun to partial shade and prefers moist, well-drained soil. Ideal for borders, meadows, and streamside plantings, it offers a bold splash of color with minimal maintenance.

Growing and Maintenance Tips for Iris chrysographes 'Black Form' (Ships in Spring)

Planting: Plant rhizomes in spring or fall, 2 to 3 inches deep with the top just below soil level. Space 12 to 18 inches apart. Choose a site where moisture is consistent but not stagnant.
Location: Full sun to partial shade. Ideal for bog gardens, pond edges, or moist borders.
Soil: Moist, humus-rich, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Avoid dry or compacted areas.
Watering: Keep soil consistently moist during the growing season. Allow the top layer to dry slightly between waterings to prevent rhizome rot.
Temperature: Hardy in USDA zones 3–9. Tolerates cold winters and thrives in cool, damp conditions.
Fertilization: Apply compost or a balanced fertilizer in early spring. Avoid overfeeding—excess nitrogen can reduce bloom quality.
Pruning: Remove spent flower stalks after blooming. Cut back foliage in late fall or early spring to tidy the plant.
Propagation: Divide clumps in midsummer to early fall. Replant divisions immediately in moist soil.
Pest & Disease: Generally pest-free. Watch for slugs, snails, and gray mold in humid conditions.
