Rare ice flowers were spotted at Missouri park. How to see the ‘once per year event’
An early bird can catch more than a worm if you venture out early enough — you might just catch a glimpse of this beautiful, intricate ice “flower” blooming on specific species of plants.
Early-morning strollers in Missouri may be lucky enough to spot the “frost flower” on stems of certain plants.
Although not technically a true flower, it is made up of thin layers of ice crystals that form on several plant species, including dittany, stinkweed and white crownbeard. Together, the layers combine to form a soft, cobweb artful appearance.
Ozark National Scenic Riverways, a national park in Van Buren, explained it was due to a perfect combination of conditions.
The air needs to be below 32 degrees, and the ground needs to be fairly warm and moist to create this perfect storm.
“This phenomenon only takes place in late fall/early winter while the ground is still warm, and the air temps begin to drop. Root systems continue to send sap up the stem which freezes upon contact with the colder air temps,” the national park said.
Not only must conditions be perfect, but the formation may happen only once.
“Practically speaking, (it is) a once per year event, although not all individuals produce frost flowers on the first day of good conditions,” the National Weather Service said.
Each of these fragile flowers are unique, the weather service said.
To find them, experts advise to look for tall weeds. According to the weather service, the particular ice-filled beauties enjoy the same environment as purple ironweed, blackberries and wingstems.
“Most frost flowers don’t last into mid-morning, so bundle up, grab your thermos and plan your route ahead of time,” the national park said.
