Plants like fennel, dill, and dogfennel share that feathery foliage, making identification tricky for gardeners. If you are trying to figure out what is growing in your herb bed or your backyard, you have likely searched for plants that look like dill. This guide will help you tell the difference between the real thing and its common lookalikes, so you can avoid a nasty surprise in your salad or soup.
Dill has a very distinct scent, but many other plants mimic its fine, thread-like leaves. Some of these are edible and useful, while others are toxic or invasive. We will walk through the most common plants that cause confusion, how to spot them, and what to do if you find them in your garden.
Why So Many Plants Look Like Dill
The feathery look is not a coincidence. Many plants in the Apiaceae family (carrot family) share this trait. This family includes carrots, parsley, celery, and fennel. They all have compound leaves that are finely divided, which creates that airy, fern-like appearance.
Because they are related, they also have similar flower structures. Most produce umbrella-shaped clusters called umbels. This makes visual identification harder, especially when the plants are young and have not flowered yet.
The key to telling them apart is often in the smell, the stem texture, and the specific leaf shape. You cannot rely on looks alone. You have to get close and use your senses.
Plants That Look Like Dill
Here is the main section you have been waiting for. We will break down the top lookalikes, starting with the most common and moving to the more obscure ones. Remember, when in doubt, do not eat it.
Fennel
Fennel is probably the closest lookalike to dill. In fact, many gardeners plant them together because they look so similar. The leaves are almost identical in color and shape. However, there is one major difference: the smell.
Fennel has a strong anise or licorice aroma. Dill smells more like a mix of lemon and grass. If you crush a leaf and smell it, you will know immediately which one you have. Also, fennel has a thicker, bulbous base at the soil line, while dill has a thin, single taproot.
Fennel is completely edible and delicious. You can use the fronds in salads, the bulb in roasting, and the seeds in spice blends. So, if you accidentally grow fennel instead of dill, you have not made a mistake. You just have a different herb.
Dogfennel
Despite the name, dogfennel is not related to fennel or dill. It is actually a species of Eupatorium, which is in the sunflower family. This plant is a common weed in the southeastern United States. It grows tall and has very fine, feathery leaves that look almost exactly like dill from a distance.
The biggest difference is the smell. Dogfennel has a pungent, somewhat unpleasant odor when crushed. Some people say it smells like turpentine or a strong, bitter herb. It is not considered safe for consumption in large amounts, though it has been used in small doses in traditional medicine.
Dogfennel also has a different growth habit. It grows upright and can reach up to six feet tall. The stems are often purple or reddish near the base. Dill is usually shorter and has green, hollow stems.
Wild Carrot (Queen Anne’s Lace)
Wild carrot, also known as Queen Anne’s Lace, is another common lookalike. In its early stages, the leaves are very similar to dill. They are finely divided and feathery. However, as the plant matures, the leaves become more broad and less delicate.
The most distinguishing feature of wild carrot is the flower. It produces a large, flat-topped white umbel. Often, there is a single dark purple flower in the center. Dill produces yellow flowers, so this is a clear giveaway if you see blooms.
Wild carrot roots are edible when young, but they can be tough and woody. However, you must be careful. Wild carrot looks very similar to poison hemlock, which is deadly. Do not dig up and eat wild carrot unless you are 100% sure of the identification.
Poison Hemlock
This is the one you need to worry about. Poison hemlock is extremely toxic and can be fatal if ingested. It looks very similar to dill, especially in the early spring. The leaves are feathery and green, but they are often more glossy and have a slightly different texture.
The best way to identify poison hemlock is by the stem. It has smooth, hollow stems that are covered in purple or red spots. Dill stems are green and have a waxy coating. Poison hemlock also has a distinct, mousy odor when crushed, which is not pleasant.
If you see a plant that looks like dill but has purple spots on the stem, do not touch it. Wear gloves to remove it, or use a herbicide. Wash your hands thoroughly if you come into contact with it. This is a serious plant that should not be taken lightly.
Yarrow
Yarrow is a common garden perennial that has feathery, fern-like leaves. It is often confused with dill, especially when it is young. However, yarrow leaves are typically more gray-green in color and have a stronger, more pungent smell. They are also slightly thicker and more textured than dill leaves.
Yarrow is not toxic, but it is not a culinary herb like dill. It has been used for medicinal purposes for centuries, mainly to stop bleeding and reduce inflammation. The flowers are usually white or pink, and they grow in flat clusters, unlike the yellow umbels of dill.
If you have yarrow in your garden, you can keep it for its medicinal properties or its attractiveness to pollinators. Just do not use it as a dill substitute in pickles. The flavor is completely different and quite bitter.
Asparagus Fern
This is a bit of a stretch, but young asparagus fern shoots can look like dill from a distance. The foliage is very fine and airy. However, asparagus fern is not a true fern. It is in the lily family and produces small, white flowers and red berries.
The main difference is the texture. Asparagus fern has slightly prickly, needle-like leaves, while dill is soft and feathery. Also, asparagus fern is a trailing or climbing plant, while dill grows upright. If you touch it, you will feel the difference immediately.
Asparagus fern is not edible. In fact, the berries are toxic to cats and dogs. If you have this plant, keep it away from pets and children. It is usually grown as a houseplant or in hanging baskets, so it is less likely to be confused with garden dill.
Parsley (Flat-Leaf And Curly)
Parsley is in the same family as dill, so they share some visual similarities. However, parsley leaves are broader and less feathery. Flat-leaf parsley has distinct, pointed leaves, while curly parsley has ruffled edges. Neither looks exactly like dill, but young plants can be confusing.
The smell is the easiest way to tell them apart. Parsley has a fresh, green, slightly peppery scent. Dill has that unique, tangy, almost sour smell. If you are growing herbs in a pot and forget to label them, crush a leaf and sniff.
Parsley is perfectly safe to eat and is a great companion plant for dill. They actually attract different beneficial insects, so planting them together is a good idea. Just keep track of which is which when you harvest.
How To Identify Dill Accurately
Now that you know the lookalikes, you need to know how to confirm you have real dill. There are a few simple tests you can do. These steps will help you avoid any dangerous mix-ups.
- Smell the leaf: Crush a leaf between your fingers. Dill has a strong, distinct aroma that is a mix of lemon, grass, and a hint of anise. If it smells like licorice, it is fennel. If it smells like turpentine, it is dogfennel. If it smells like nothing or smells musty, be cautious.
- Check the stem: Dill has a hollow, green stem that is smooth and slightly waxy. It does not have purple spots. If you see purple or red blotches, it is likely poison hemlock. Do not touch it.
- Look at the leaf structure: Dill leaves are very fine and thread-like, almost like soft needles. They are delicate and feathery. If the leaves are thicker, broader, or have a different texture, it is not dill.
- Examine the base: Dill grows as a single, upright stalk with a thin taproot. It does not have a bulbous base like fennel. If you see a swollen, bulb-like structure at the soil line, it is fennel.
- Wait for flowers: If the plant is mature, look at the flowers. Dill produces yellow, umbrella-shaped clusters. If the flowers are white, it is likely wild carrot or poison hemlock. If they are pink or white and flat-topped, it might be yarrow.
Following these steps will give you a high level of confidence. But remember, when in doubt, throw it out. It is better to buy a bunch of dill at the store than to risk eating a toxic lookalike.
Edible Lookalikes You Can Use
Not all lookalikes are bad. Some are actually great additions to your kitchen. If you have fennel, you can use it in many recipes. The fronds are great in salads, and the bulb is wonderful roasted or grilled.
Wild carrot roots are edible, but they are best when harvested young. They have a carrot-like flavor but are often tougher and less sweet. You can use them in soups or stews. Just be absolutely sure you have wild carrot and not poison hemlock.
Yarrow is edible in small amounts. The young leaves can be added to salads for a bitter, peppery kick. However, it is not a culinary staple. It is more of a medicinal herb. Use it sparingly and with caution.
If you are looking for a dill substitute for pickling, fennel fronds are your best bet. They do not taste exactly like dill, but they add a similar texture and a unique flavor. You can also use a mix of fennel and parsley to get closer to the dill taste profile.
Toxic Lookalikes To Avoid
This is the most important part of this article. Poison hemlock is a deadly plant. It is responsible for many accidental poisonings each year because it looks so much like edible plants. Do not rely on memory or a quick glance. Use the identification steps above.
Dogfennel is not deadly, but it is not safe to eat in large quantities. It contains compounds that can be toxic to the liver. It is best to avoid it altogether. If you have it in your yard, pull it out and dispose of it.
Asparagus fern is toxic to pets. If you have it in your home, keep it out of reach of cats and dogs. It is not likely to be confused with dill in a garden setting, but it is worth mentioning for indoor gardeners.
Always wear gloves when handling unknown plants. Some plants can cause skin irritation or allergic reactions. Wash your hands after gardening, and never put a plant in your mouth unless you are 100% certain of its identity.
Common Growing Conditions For Dill
If you want to grow real dill, you need to provide the right conditions. Dill is an annual herb that prefers full sun. It likes well-drained soil that is rich in organic matter. It does not like to be transplanted, so it is best to sow seeds directly in the garden.
Dill grows quickly and can reach heights of three to four feet. It will bolt (go to seed) in hot weather, so it is best to plant it in the spring or fall. You can also plant it in succession every few weeks to have a continuous harvest.
Dill attracts beneficial insects like ladybugs and lacewings. It also attracts swallowtail butterfly caterpillars. So, it is a great addition to a pollinator garden. Just be aware that it will self-seed, so you might have volunteer dill plants next year.
If you are growing dill for pickling, harvest the leaves before the plant flowers. The leaves have the best flavor when they are young and tender. You can also harvest the seeds once the flowers fade and the seed heads turn brown.
