Frostweed, or Verbesina virginica, is an herbaceous wildflower native to the eastern half of North America. A perennial, frostweed is a hardy, fast-growing plant that thrives in sunny, well-drained soil. It is often found on roadsides, fields, and other disturbed areas.

Frostweed has been named for its propensity to form dramatic ice sculptures on cold winter days. On sunny days, the plant’s thick stems will exude a milky-white sap that quickly solidifies in cold temperatures. As the sap freezes and expands, the stems will split into several pieces, forming intricate patterns of ice known as “frost flowers”. The thick stems of the plant can remain frozen for days, making for a truly spectacular sight.

How to Grow Frostweed in the Garden


Growing this striking wildflower requires specific habitat requirements, and with a little knowledge and effort, you can have a beautiful display of Frostweed in your own backyard.

The best habitat is in moist, sunny meadows and open woodland areas with plenty of sun and air circulation. This wildflower prefers moist, well-draining soils with plenty of organic matter, and it does not tolerate soggy conditions. It will not bloom if the soil is too dry or too wet, so it is important to monitor soil moisture.

Frostweed is best suited to areas with temperate climates, although it can be grown in more extreme climates with some modifications. In hotter climates, it is important to give Frostweed protection from the afternoon sun and provide plenty of water during dry spells. In colder climates, planting it in a protected spot with plenty of snow cover will provide extra insulation and help your plants survive the winter.

Frostweed is a short-lived perennial, so it is important to provide it with plenty of nutrients. Fertilizing with a slow-release, low-nitrogen fertilizer will help promote healthy growth and encourage blooms. Mulching around the plants with organic material such as compost or bark chips will help keep the soil moist and reduce the need for frequent watering.

Frostweed is a self-seeding plant, so you will need to keep an eye on it and remove any unwanted seedlings. If left to its own devices, it can become invasive in some areas.

Soil and Light Requirements

Frostweed is a hardy, native wildflower that typically grows in sunny, open areas. It is tolerant of a wide range of soils, but it prefers well-drained soil with a neutral pH. To ensure Frostweed thrives in your garden, it’s important to prepare the soil ahead of time. Dig the soil up to a depth of 6 inches and remove any weeds or debris. Amend the soil with organic matter such as compost or manure. This will help improve drainage and water-holding capacity.

When it comes to light requirements, Frostweed does best in full sun. It will tolerate partial shade but may produce fewer blooms. If you are planting Frostweed in a shady area, make sure it receives at least 6 hours of direct sunlight each day.

Frostweed is a low-maintenance wildflower that is easy to grow. With the right soil and light requirements, it can be an attractive addition to any garden.


Propagating Frostweed (Verbesina virginica) is a rewarding and enjoyable experience for any wild plant enthusiast. But despite its beauty and hardiness, Frostweed can be a tricky plant to propagate. That’s why it’s important to know the best propagation methods for this species, so you can successfully grow your own Frostweed from seed.

The first step in propagating Frostweed is to collect the seeds. Frostweed blooms in late summer and the seeds are dispersed by the wind. To collect the seeds, simply wait until the flower heads turn brown and dry out. Then, cut the flower heads off and place them in a paper bag. Shaking the bag vigorously will disperse the seeds.

Once the seeds are collected, it’s time to sow them. Frostweed prefers a sunny spot with rich, well-drained soil. Sow the seeds in mid-autumn, broadcasting them over the soil surface. Cover them lightly with a thin layer of compost and then water them in.

It is a slow-growing species, so it may take several weeks before you see the first signs of germination. Once the seedlings emerge, thin them to give each plant enough space to grow. Keep the soil moist, but not wet, and fertilize the plants every few weeks with a balanced fertilizer.

Frostweed can also be propagated through division. In late autumn or early winter, dig up the clumps of Frostweed and divide them into smaller pieces. Replant the divisions in the same spot or a new location.

Finally, it can also be propagated from cuttings. Take cuttings from the tips of the stems in late summer or early autumn. Cut the stems into pieces about 4 inches long and strip away the lower leaves. Dip the cuttings in rooting hormone, then plant them in pots of moist potting soil. Place the pots in a sunny spot and keep the soil moist.
