White trout lily: Diseases and Remedies (Explained for Everyone)

NOTE: The terms White trout lily and Erythronium albidum are identical in this text; in reality, Erythronium albidum is White trout lily’s biological word.

Most of the wildflower species in the Erythronium genera are native to North America. They are referred to as “trout lilies” or “dogtooth violets”, though “trout lilies” is the more accurate name. White trout lilies or white dogtooth violet are the names of the species, Erythronium albidum. In the central and eastern United States, it is native to shady woodland areas.

There is a small bell-shaped white flower in the white trout lilies that lasts for about two weeks in the spring. The leaves are gray-green, brown or red, and are said to resemble the skin of a trout. This plant grows from a tiny corm that will gradually spread to produce offset plants that form their own corms.

A good ground cover for shady areas will be formed over time by dense colonies of white lilies trout. It’s important for bees to have a rich supply of trout lily because it’s an important food for them. White trout lily is a rather subtle plant that appeals mostly to native plant and wildflower enthusiasts, so gardeners interested in a spectacular show might be disappointed.

Why does my Erythronium albidum roots have rot?

If left untreated, root rot on your White trout lily (Erythronium albidum) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.

Why does my White trout lily have gray mold spots?

Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.

Our Solution

The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Erythronium albidum being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.

Why are my White trout lily leaves turning yellow?

In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.

Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:

Here are some indicators of yellowing on the Erythronium albidum brought on by its numerous flaws:

  • Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last.
  • Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
  • The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
  • Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
  • Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.

Our Solution

You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.

Is my White trout lily sunburned?

It is quite easy to find out if your White trout lily (Erythronium albidum) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.


As we saw above, the leaves of your White trout lily can also change color if it receives too much water or insufficient light.

However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.

Why are my White trout lily leaves turning brown?

A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.

Should I leave my Erythronium albidum in direct sunlight?

No! If your Erythronium albidum (or White trout lily) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your White trout lily is in such a state!

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s White trout lily so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.

Why are my Erythronium albidum leaves drooping or wilting ?

In most cases, this happens when your Erythronium albidum lacks water. This is especially the case for large plants, naturally they need more water than others.


An easy way to know if your Erythronium albidum is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!

Our Solution

If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the White trout lily right away after a dry time because you think it needs a lot of water.

This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.

Caring Tips for Erythronium albidum

Water Occasionally

Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.

Touching the soil will let you know whether your plant needs water or not; if it still feels damp, it’s generally best to wait a few more days.

Always keep temperatures stable

Maintaining a consistent temperature for your Erythronium albidum is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Erythronium albidum close to air conditioners, radiators, or other sources of hot or cold air.

Keep your White trout lily Dust-Free

This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.

This would also make the pests happy, a real descent into hell for your White trout lily.

Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!

Keep drainage in mind

If you have a tendency to overwater, you need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.

In the meantime, if you don’t have holes in your pots, you can add volcanic rocks (or any rocks with holes) at the bottom of your pot, this way it will create a channel so that the water doesn’t stay in your skin too much (to avoid that roots start to rot!)
