What is the difference between a trout lily and a fawn lily?

Trout lilies and fawn lilies are both beautiful spring flowers that can add a touch of elegance to any garden or landscape. While they may seem similar at first glance, there are some distinct differences between these two types of lilies.

1. Appearance:
– Trout lilies (Erythronium americanum) are named for their leaf mottling, which resembles a trout swimming through water. The leaves have a distinct pattern of brown or purple spots on a green background.
– Fawn lilies (Erythronium oregonum) get their name from the spotted leaves, which are said to resemble the upright ears of a fawn. The spots are usually a lighter shade of green or yellow.

2. Petal shape and color:
– Trout lilies have six petals that are usually yellow in color. The petals are long and narrow, with a pointed tip, giving them a somewhat lily-like appearance.
– Fawn lilies also have six petals, but they can come in a variety of colors, including shades of pink, purple, or white. The petals are broader and more rounded compared to trout lilies.

3. Leaf shape and size:
– Trout lily leaves are lance-shaped and typically measure around 5-15 centimeters in length. The leaves emerge before or alongside the flowers and form a carpet-like foliage.
– Fawn lily leaves are heart-shaped and can be quite large, ranging from 10-30 centimeters in length. The leaves usually appear after the flowers have bloomed and add a lush, green backdrop to the garden.

4. Growing conditions:
– Trout lilies are native to Eastern North America and thrive in woodland settings with moist, well-draining soil. They prefer partial shade and can be found growing in forested areas or near streams and rivers.
– Fawn lilies are native to the western United States and are commonly found in woodland habitats and meadows. They prefer well-drained soil and can tolerate both full sun and partial shade.

5. Bloom time and duration:
– Trout lilies typically bloom in early spring, usually around March or April, depending on the region and weather conditions. The flowers usually last for a few weeks before fading away.
– Fawn lilies bloom slightly later than trout lilies, often in April or May. They also have a relatively short bloom period, lasting for a couple of weeks.

While both trout lilies and fawn lilies belong to the Erythronium genus and share some similarities, they have distinct differences in terms of appearance, petal shape, leaf shape, growing conditions, and bloom time. These unique characteristics make each of them a delightful addition to any garden or landscape, adding a touch of natural beauty and charm.
