WaterTo maintain a healthy Toffee Twist, water it deeply once a week, providing about 1 to 1.5 gallons of water each time, depending on the weather and soil conditions. During hotter, dryer periods, you may need to water it more frequently, possibly twice a week, to keep the soil moist but not waterlogged. Reduce watering in cooler months to prevent root rot. Always check the top inch of the soil before watering; if it feels dry, it's time to water again.
LightToffee Twist thrives in full sun to partial shade, meaning it requires at least 4-6 hours of direct sunlight per day, with some relief during the hottest part of the afternoon. The ideal spot would be one that gets bright morning light and dappled or light shade in the afternoon to protect its foliage from scorching.
TemperatureToffee Twist does well in a wide range of temperatures but prefers conditions between 65°F and 75°F for optimal growth. It can tolerate minimum temperatures down to 20°F but should be protected from frost to avoid damage. Maximum temperatures should not exceed 90°F for extended periods as excessive heat can stress the plant.
PruningPruning Toffee Twist is primarily for aesthetic purposes and to remove any dead or damaged foliage, enhancing its appearance and promoting healthy growth. Prune in late winter or early spring before the onset of new growth. Cut back up to one-third of the older stems to allow light into the center of the plant for better air circulation.
CleaningAs needed
SoilThe New Zealand Iris, 'Goldfinger' thrives in a well-draining soil mix with a slightly acidic to neutral pH of 6.5 to 7.2. A mixture containing equal parts of loam, sand, and peat or compost is ideal. Ensure the mix allows for good aeration and drainage to prevent waterlogging, which can be detrimental to the plant's health.
RepottingNew Zealand Iris 'Goldfinger' does not require frequent repotting and should be repotted every 2 to 3 years or when it has outgrown its current container. This slow-growing plant prefers to be somewhat root-bound, so avoid repotting too often unless necessary to refresh the soil or divide the rhizomes.
Humidity & MistingNew Zealand Iris 'Goldfinger' is tolerant of a range of humidity levels but prefers moderate humidity. It can thrive in both drier conditions and in areas with higher humidity, reflecting its adaptability to various garden settings.
Suitable locationsIndoor
Place in bright, indirect light with well-draining soil.

Life cycleLibertia ixioides 'Goldfinger', commonly known as New Zealand iris 'Goldfinger', initiates its life cycle as a seed, germinating in moist, well-drained soil in a sunny or partially shaded location. Once the seedling emerges, it grows into a clump-forming perennial, developing narrow, upright, sword-like leaves that are golden-yellow in color. The plant enters a vegetative stage, where it focuses on leaf growth and establishing a robust root system. After the vegetative phase, usually in late spring to early summer, the New Zealand iris produces white, iris-like flowers on stems that rise above the foliage. Following the flowering stage, seed capsules form and mature, eventually releasing seeds to start the next generation. The plant typically maintains a healthy appearance year-round, with die-back occurring in parts of the clump as it becomes overcrowded, necessitating division and propagation to rejuvenate and continue the life cycle.
PropogationPropogation time
Spring to summer
Propogation: Dividing established clumps is the most popular method for propagating Libertia ixioides 'Goldfinger', commonly known as New Zealand Iris. This process is typically done in the spring or early summer, when the plant is actively growing. To divide the plant, gently lift the entire clump from the ground, being mindful of the fragile root system. Using a sharp, clean knife or spade, the clump is cut into smaller sections, ensuring that each section has several growing points. The divisions are then replanted in moist, well-draining soil, spaced about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow sufficient room for growth. After planting, it's essential to water the new divisions thoroughly to help establish them in their new location.
