Tweedy’s Cat’s Ear: A Lesser-Known Perennial Wildflower

Meet Tweedy’s cat’s ear (Hypochaeris brasiliensis var. tweediei), a perennial wildflower that’s quietly made itself at home across the southeastern United States. While not as famous as its dandelion relatives, this unassuming member of the Asteraceae family has an interesting story to tell.

What Exactly Is Tweedy’s Cat’s Ear?

Tweedy’s cat’s ear is a perennial forb – essentially a non-woody flowering plant that comes back year after year. Like other plants in the cat’s ear family, it gets its quirky common name from the shape and texture of its leaves, which supposedly resemble a cat’s fuzzy ear. This particular variety is named after botanist Frank Tweedy, who contributed significantly to our understanding of North American flora.

Botanically speaking, this plant goes by several scientific names throughout history, including Hypochaeris tweediei and various other spellings that reflect the evolving nature of plant taxonomy.

Where You’ll Find It Growing

Tweedy’s cat’s ear has established itself across eight southeastern states: Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Texas. It’s important to note that this plant isn’t native to North America – it’s an introduced species that has naturalized and now reproduces on its own in the wild.

Should You Grow Tweedy’s Cat’s Ear?

Here’s where things get a bit complicated. While Tweedy’s cat’s ear isn’t currently listed as invasive or noxious, its non-native status means it doesn’t provide the same ecological benefits as native plants. Native plants have co-evolved with local wildlife, offering superior food sources and habitat for native birds, butterflies, and beneficial insects.

If you’re drawn to this plant’s characteristics, consider exploring native alternatives that can provide similar aesthetic appeal while supporting your local ecosystem. Your local native plant society or extension office can recommend beautiful native forbs that thrive in your specific area.

Growing Considerations

Unfortunately, specific growing information for Tweedy’s cat’s ear is limited in available literature. As a perennial forb, it likely shares some characteristics with related species in the Asteraceae family. However, without detailed cultivation information, it’s difficult to provide reliable planting and care advice.

If you encounter this plant growing wild in your area, it’s worth observing its preferred conditions – noting the soil type, moisture levels, and sun exposure where it thrives naturally.

The Bigger Picture

While Tweedy’s cat’s ear represents an interesting example of plant naturalization in the Southeast, gardeners today have incredible opportunities to create beautiful landscapes using native species. Native plants offer numerous advantages:

  • Better adaptation to local climate and soil conditions
  • Reduced need for watering and fertilizers
  • Superior wildlife habitat and food sources
  • Preservation of regional ecological character

Before adding any non-native plant to your garden, consider researching native alternatives that can provide similar beauty while supporting the intricate web of life in your local ecosystem. Your garden can be both gorgeous and ecologically beneficial – it just takes a little research to find the perfect native plants for your space.

Hypochaeris brasiliensis var. tweediei is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Hypochaeris brasiliensis var. tweediei is also known as:

Hypochaeris brasiliensis & ex var. tweedyi Baker, orth. var. | USDA symbol: HYBRT
Hypochaeris elata auct. non | USDA symbol: HYEL5
Hypochaeris tweedyi & , orth. var. | USDA symbol: HYTW
Hypochaeris tweediei & | USDA symbol: HYTW2

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
