Iris pseudacorus 'Berlin Tiger' is a cultivar of Iris pseudacorus, commonly known as Yellow Flag Iris. It is a tall and striking perennial that produces large, yellow flowers with unique tiger-like markings. Here's a detailed description and care guide for Iris pseudacorus 'Berlin Tiger':

Iris pseudacorus 'Berlin Tiger' features tall, erect stems that can reach a height of 90-120 cm (36-48 inches). The flowers are large and showy, measuring around 10-12 cm (4-5 inches) in diameter. They have six broad, bright yellow petals with distinctive dark brown or purple markings that resemble tiger stripes. The flowers bloom in late spring to early summer and create a stunning display in the garden. The foliage is long and sword-shaped, with a rich green color. It forms dense clumps of arching leaves that add texture and interest even when the plant is not in bloom.

Care Guide:

Light: Iris pseudacorus 'Berlin Tiger' thrives in full sun to partial shade. It prefers at least 6 hours of direct sunlight per day to promote optimal flowering. However, it can tolerate some shade, especially in regions with hot summers, where it benefits from protection against intense afternoon sun.

Water: Yellow Flag Iris prefers consistently moist soil. It is a water-loving plant and thrives in wet or boggy conditions. Ensure the soil is evenly moist but not waterlogged. It can tolerate short periods of standing water, but prolonged waterlogging should be avoided. Regular watering is important, especially during dry spells or in sandy soil.

Soil: Iris pseudacorus 'Berlin Tiger' prefers fertile, loamy soil that is slightly acidic to neutral pH. It can tolerate a wide range of soil types, including clay, loam, or sandy soil. The soil should be moist and well-draining to prevent waterlogging. Amending the soil with organic matter, such as compost or well-rotted manure, before planting can improve its fertility and moisture retention.

Temperature: Yellow Flag Iris is hardy in USDA hardiness zones 4-9. It is adaptable to various climate conditions but performs best in areas with cool to mild summers. It can tolerate both heat and cold, but in regions with extremely hot summers, providing some shade during the hottest part of the day can help protect the plant.

Fertilizer: Yellow Flag Iris is generally a low-maintenance plant that doesn't require heavy feeding. However, you can apply a balanced slow-release fertilizer in early spring or incorporate a granular fertilizer into the soil before planting. Follow the package instructions for application rates. Avoid excessive use of nitrogen-rich fertilizers, as they can promote lush foliage growth at the expense of flower production.

Pruning: Minimal pruning is required for Yellow Flag Iris. After the flowering period, you can remove any spent flower stalks to maintain a neat appearance. In late fall or early spring, you can trim back the leaves to a few inches above the ground to allow for new growth.

Pests and Diseases: Yellow Flag Iris is generally resistant to pests and diseases. However, it may occasionally be affected by aphids, iris borers, or snails. Monitor your plants regularly and take appropriate measures to control any infestations. Good air circulation and proper spacing between plants can help prevent fungal diseases.

Iris pseudacorus 'Berlin Tiger' is a stunning and eye-catching perennial that adds vibrant color and unique markings to garden beds, borders, or water gardens. By providing the right growing conditions and proper care, you can enjoy the striking flowers and architectural foliage of this cultivar in your landscape.

Here are some general tips and care guidelines for marginal pond plants:


Research different species of marginal pond plants to find ones that suit your pond's conditions and your aesthetic preferences. Consider factors such as height, flower colour, foliage texture, and seasonal interest when selecting plants.


Observe the natural conditions of your pond, such as sun exposure, soil type, and water movement, and choose plants that are adapted to those conditions. Create different planting zones around the pond, with plants that prefer wet soil closer to the water's edge and those that tolerate drier soil further away.


Marginal plants typically thrive in full sun to partial shade. Some species can tolerate more shade, but for optimal growth and flowering, provide them with at least 6 hours of direct sunlight per day.

Water Depth:

Determine the water depth requirements of the marginal plants you choose. Some plants prefer water up to 6 inches deep, while others can tolerate water up to 12 inches or more. Ensure that the water level remains consistent within the preferred range for the chosen plants.


Marginal plants prefer a rich, loamy soil that retains moisture but is not waterlogged. Amend the soil with organic matter, such as compost or well-rotted manure, to improve its fertility and drainage. Avoid using heavy clay soil, as it can become compacted and restrict root growth.


Dig a hole slightly larger than the root ball of the plant and loosen the soil at the bottom. Place the plant in the hole, ensuring that the crown is level with or slightly above the soil surface. Backfill the hole with soil and gently firm it around the plant to eliminate air pockets. Water thoroughly after planting to settle the soil and provide initial hydration.


Apply a layer of organic mulch around the base of the plants to suppress weeds, conserve moisture, and regulate soil temperature.Use materials like straw, shredded bark, or compost, and maintain a depth of 2-3 inches.


Marginal plants prefer consistently moist soil but should not be waterlogged. Monitor the moisture level regularly and water as needed to keep the soil evenly moist. During hot and dry periods, provide supplemental watering to prevent the soil from drying out.


Marginal plants generally do not require heavy fertilization if the soil is nutrient-rich. However, if growth appears weak or leaves show signs of nutrient deficiencies, apply a balanced slow-release fertilizer according to the manufacturer's instructions.


Remove any yellowing or dead leaves to maintain plant health and appearance. Divide overcrowded plants every few years to prevent competition for resources and promote vigorous growth. Prune back excessive growth to maintain a tidy appearance and to prevent plants from encroaching on other plants or the pond itself.

Winter Care:

Hardy marginal plants can withstand winter temperatures and require minimal care. Cut back dead foliage in late fall or early spring to tidy up the planting area. In colder regions, consider protecting tender plants with a layer of mulch or covering them with burlap during winter to prevent frost damage.

Monitoring and Troubleshooting:

Regularly inspect plants for signs of pests, diseases, or nutrient deficiencies. Address any issues promptly with appropriate treatments, such as organic insecticides, fungicides, or nutrient amendments. By following these detailed tips and providing proper care, you can create a beautiful and thriving planting zone around your pond, enhancing its visual appeal and supporting a diverse ecosystem.
