Panicum Elegans ‘Frosted Explosion’

Panicum elegans 'Frosted Explosion'

Trial: Annual

Year Trialed: 2008

Good Qualities:

In a bouquet, it added an airy feature; Good filler, dries well; Lacy filler, not the norm, pleasing shape (upside down cone); Liked to use these early on until they ‘exploded’, this explains for low stem counts; Feathery, light appearance was very complimentary to other cut flowers, vast majority of stems were 18-20 inches, very few were shorter; Light airy texture; nice green color with darker panicles, great as a filler both fresh and dried, the most popular flower in our ASCFG cut flower trials; I especially liked this grass in its less mature, tufted stage – like a fine grass tassel on a stem! Made a very textural filler – nice bright green color, nice long useful life in field, will definitely be growing this again!; One of the most productive, in demand crops I grew, we never had enough and sowed twice plus cut from a batch of volunteers, this stuff is so easy to grow, easy to cut, the wholesaler and grocery stores love it and consumers can’t get enough; Very cool plant, everyone loved it; Frosted Explosion was easy to germinate, transplant, and grew vigorously, in fact it responded well to watering and fertilizing; Easy to grow, wonderful customer approval, long lasting and great filler for bouquets; Unusual flower type.


None (2); Too short (2); Looked too much like a weed for most people; Fragile; Stems can bend; Cut in early development or the tops become thin and brittle; First cut produced huge number of stems, following cuts weren’t as lucrative; Longer stems would be desirable; Will grow it again, for sure, and hope for longer stems, but even short, it was a winner!; Hard to use after it started to branch, maybe additional sowings would be better, sheds some seeds; All plants were almost dead, the results are from 1 small plant that barely survived, not sure cause of stress.

Similar Cultivars:

Native switch grass, a weed here!; No; There is a weedy grass in my fields that is identical to ‘Frosted Explosion’, I do not water or fertilize the weed but it grew similar to the cultivar and had the same inflorescence, in fact I have used the weed years previously in bouquets, for my customers, it was too common as they all have it as a weed in their gardens as well.


I think I planted these too close, I didn’t love it, but New England doesn’t have the love for grasses that some areas do, what I do love is how it works as a dried “flower”; Adds a natural look to informal bouquets; Perennial grass/ we grow as annual looks like our wild grass which we cut; Died in a cold weather snap in early spring; Japanese beetles enjoyed hanging out in the feathery ends, but thankfully didn’t seem to eat foliage; Crop failure, was weeded out, this is a weedy annual grass here in Wisconsin; Should be cut flower of the year!; Love it!; Lasted for the entire growing season, everyone remarked about it and wanted to know what it was.


Choose green inflorescences that are just getting a bronze tip to avoid messy arrangements; Water and bleach; Cut into Floralife; We only used plain water.
