| Positive | On Jul 12, 2020, Bandita74 from Mount Ivy, NY wrote: I grew this from gifted seed from a friend not really knowing what it was. Last year it topped over 8 feet tall in my zone 6b garden! Every sort of pollinator imaginable was loving this plant, especially migrating monarchs. I trimmed it back early this season in hopes it will bloom a bit lower this year because it was shading out my Joe Pye and my goldenrod. It’s a late season bloomer so provides interest when other flowers are dying out in the garden and bloomed for me until frost. I’ve heard it can get pretty aggressive but so far the clump I have has not really expanded much so I’m giving it a positive review for the pollinator action. |
| Positive | On Oct 3, 2018, originaljazzgirl from Fairfax, The flowers are great for my monarchs, and the thing is so strong-stemmed that it doesn't need staking. Mine get to 10' tall. The first year they self-sowed so much that now in the fall I make sure to chop the flowerheads. But I leave the lower stems of course, because the best part about this plant are the beautiful ice sculptures. Plant is really easy to grow either from seeds or transplants. This past summer I transplanted some in 90 degree heat (no idea why I did that) and they actually made it, they are blooming now. |

| Positive | On May 30, 2014, goofballTex from Plano, TX (Zone 8a) wrote: Frostweed is a wonderful native plant. However, like most members of the aster family, its seeds get absolutely EVERYWHERE, so unless you have a lot of land to work with, clip the flower heads after they're done blooming to save yourself the trouble of pulling up seedlings where they're not wanted all next year. The good thing is that they're easy to pull. |

| Positive | On Jul 3, 2008, Sheila_FW from Fort Worth, TX (Zone 8a) wrote: Frostweed is a very hardy grower and reseeds generously. So if you don't have the space clip the blooms before they drop seeds. I agressively prune mine so they are not so tall in my beds. I have enjoyed having Frostweed in the shade and sun, and also enjoyed watching a large variety of butterflies that nectar on it. The native plant is also a larval host plant for butterflies. Three that are in Texas are the Bordered Patch, Silvery Checkerspot, and the Summer Azure. |
| Neutral | On Feb 27, 2004, MotherNature4 from Bartow, FL (Zone 9a) wrote: This plant grows almost all over the state of Florida. It loves sunny, wet ditches and open hammocks. It is most attractive in late fall when the white flowers are covering the plants. Considered a large weed, people don't usually grow it in their yards. |
| Positive | On Feb 26, 2004, frostweed from Josephine, Arlington, TX (Zone 8a) wrote: Frostweed is a wonderful plant that will tolerate both full sun and full shade. The leaves are lovely all season and the white blossoms are delicate and beautiful. In cold winters the stem will burst after a hard frost and a frothy ice will form on the stem, thereby the name Frostweed. |
