fawn lily 'Eirene'


The appearance of the Erythronium 'Eirene', commonly known as the dog's-tooth violet, is quite charming due to its distinctive flowering characteristics and foliar patterns. The plant features elegant, nodding flowers that have a unique shape, often resembling a Turk's cap lily with recurved petals. These petals are typically creamy-white to pale pink in color, which brings a soft and delicate look to the plant. Below the flowers, the foliage of the dog's-tooth violet forms a lush undergrowth with leaves that have a distinctive mottled pattern. The green leaves are often marked with a marbled blend of darker shades, sometimes appearing in striking contrast as purplish-brown blotches. This mottling effect adds visual interest even when the plant is not in bloom. The plant has a slender stem which supports the flower, with the foliage growing close to the ground. Collectively, these features create an attractive and dainty display in the spring when the dog's-tooth violet is in bloom, adding a splash of color and texture to woodland gardens, shaded borders, or naturalized areas. The pleasing appearance of Erythronium 'Eirene' makes it a beloved choice among garden enthusiasts who are looking for a touch of elegance in semi-shaded areas of their gardens.

  • water dropWater

    Trout lilies, including Erythronium 'Eirene', prefer consistently moist soil, especially during the spring growing season. Water the plant deeply once a week, providing about 1 gallon of water per square yard of soil. During the active growth period in spring, check the soil moisture regularly and adjust watering if rainfall occurs to maintain moist soil. Reduce watering frequency as the foliage begins to die back after flowering, since these plants go dormant in the summer. It is crucial not to overwater during dormancy as this can lead to bulb rot.

  • sunLight

    Trout lilies like Erythronium 'Eirene' thrive best in dappled sunlight, similar to their native woodland habitat. They should be planted in a location that mimics the light filtering through the trees. Full morning sun with afternoon shade or light filtered through a deciduous canopy is ideal. They should be sheltered from the intense heat of the midday sun.

  • thermometerTemperature

    Trout lilies, such as Erythronium 'Eirene', are hardy and can survive in temperatures as low as 20°F and as high as 75°F. They enjoy cooler climates and are best suited to temperatures ranging from 50°F to 70°F which aligns with the typical spring weather in their native environment. These plants enter dormancy when summer temperatures rise, so they are adapted to a wide temperature range throughout the year.

  • scissorsPruning

    Trout lilies such as Erythronium 'Eirene' do not typically require pruning. However, after flowering, it's beneficial to remove spent flowers to prevent the plant from expending energy on seed production. Cut back the foliage only after it has turned yellow and died back naturally, usually several weeks after blooming. This usually takes place in late spring or early summer.

  • bambooSoil

    Dog's-tooth violet (Erythronium 'Eirene') thrives in a soil mix composed of well-draining, humus-rich medium with a pH ranging from 6.0 to 7.0. A blend of equal parts loam, leaf mold, and coarse sand or perlite creates an ideal environment.

  • plantRepotting

    Dog's-tooth violet typically doesn’t require frequent repotting. It is best to repot these plants every 3-4 years or when the bulbs have multiplied and seem crowded in their current container.

  • circleLife cycle

    The Erythronium 'Eirene', commonly known as Pagoda Dogtooth Violet or Trout Lily, begins its life as a bulb, which lies dormant underground during the winter months. In early spring, the bulb sends up a sprout that develops into one or more basal leaves, typically mottled with a unique pattern, signalling the vegetative stage. As the plant matures, a flower stalk emerges, topped with a distinctive nodding flower, usually in shades of pink or purple, marking the reproductive stage. After pollination, possibly by bees or other insects attracted to the flower's nectar, the plant forms a seed capsule. Once the seeds mature, they are dispersed by various means, such as by water or animals, giving rise to new plants and completing the cycle. The foliage dies back after the seeds are shed, and the plant re-enters dormancy until the following spring.

    • Propogation time

      Late summer-early autumn

    • Propogation: Erythronium 'Eirene', commonly known as the dog's tooth violet or trout lily, is propagated primarily through division. The best time to propagate this plant is in the late summer to early fall when the foliage has died back and the plant is dormant. To propagate by division, carefully dig up the bulbs and gently separate them, making sure each division has at least one growth point. After dividing, replant the bulbs at the same depth they were originally growing, which is typically about 3 inches (approximately 7.6 centimeters) deep, and spaced approximately 4 to 6 inches (10 to 15 centimeters) apart to give them room to grow. Water the newly planted bulbs well to help establish them. This method allows for preserving the genetic traits of 'Eirene' and will lead to flowering in subsequent seasons as the bulbs mature and naturalize in their location.
