Texas Frostweed (Verbesina virginica) is a hidden gem among native wildflowers. Known for its tall stalks, vibrant green leaves, and clusters of small white flowers, this plant serves as a vital nectar source for pollinators like monarch butterflies during their fall migration. But Frostweed isn’t just a warm-season hero—it has a unique wintertime trick that turns heads and invites awe from nature lovers.

The Winter Wonder: Frost Flowers

When temperatures dip below freezing, Frostweed performs a natural phenomenon that earns its name. As the sap in the plant’s stems expands due to freezing temperatures, it pushes water through tiny cracks in the stem. Once exposed to the cold air, this water freezes into delicate ribbons of ice, creating stunning “frost flowers” or ice sculptures. These formations are fleeting but breathtaking, often appearing early in the morning and melting as the day warms. This usually only happens with the first frost of the season.

Why Frostweed is Essential for Pollinators

In addition to its wintertime display, Texas Frostweed is a critical plant for fall pollinators. Its late-season blooms provide much-needed nectar for bees, butterflies, and other insects preparing for winter. For monarch butterflies in particular, Frostweed offers vital energy as they embark on their long migration south.

How to Grow and Care for Frostweed

Want to bring the magic of Frostweed to your garden? It’s easier than you think.

Frostweed thrives in partial to full sunlight and prefers well-drained soil. As a native wildflower, it is relatively low maintenance and drought-tolerant once established.

Here’s how to care for it:

• Planting: Sow seeds in late fall to allow natural cold stratification. This helps the seeds germinate in spring.
• Watering: Water regularly until the plant is established, then reduce frequency. Frostweed tolerates Texas’s dry conditions well.

If you live in North Texas and have a shady part in your yard, please strongly consider planting this native wonder.

Go on a Frostweed Hunt

This winter, gather your family or friends and head outdoors during the first frost to search for Frostweed’s magical ice ribbons.
