Iris louisiana 'Black Gamecock'
black gamecock Louisiana iris
Gulf Coast of the United States (Louisiana iris group)
Overview
Iris spp. 'Black Gamecock' is a Louisiana iris, growing 24–36 inches (60–90 cm) tall and 18–24 inches (45–60 cm) wide. Deep blue-violet to near-black flowers 4–5 inches (10–13 cm) with a yellow signal (stripe) on the falls — the dark color is among the deepest in the Iris spp. genus. Louisiana irises are a group of five species native to the Gulf Coast of the United States (I. fulva, I. brevicaulis, I. giganticaerulea, I. hexagona, I. nelsonii). 'Black Gamecock' is a hybrid within this group. Grows from fibrous rhizomes planted 1–2 inches (2.5–5 cm) deep (shallow, like bearded iris). Tolerates standing water and boggy conditions — native to swamps, bayous, and wet meadows of the Gulf Coast. Broader soil pH tolerance (5.5–7.0) than Japanese iris (I. ensata), which requires strongly acidic conditions (pH 5.0–6.5). Full sun to partial shade. Deciduous. Mildly toxic to dogs and cats. Deer-resistant. Zones 4–9 — hardier than the native Gulf Coast range would suggest. Iris borer in northern regions. The sword-shaped foliage remains through summer after flowering. Divide every 3–4 years. Growth rate is moderate. Suited to pond margins, rain gardens, and consistently moist borders. Containers of 3+ gallons (12+ liters) kept in water-filled saucers.
