As usual, I found this plant on the less travelled and less-often mowed southeast strip. If the mowers come through regularly this summer, the plant ought not to cause any trouble in the bigger fields. Of course, there are so many allergens in the Austin air, molds not the least of them, we may not even notice the Pig Weed.
A quick survey of a site called pollenlibrary.com tells us that there are more than a dozen kinds of Pigweed, and that the plant is a Central Texas native. Also, it can grow up to 28 feet tall! Some of the Pig Weeds have lovely names, such as Love-Lies-Bleeding, Careless weed, Rough-Fruit, and Tumbleweed. Even the plant's family name sounds like a character from Shakespeare: Amaranth. (According to my wildflower handbook, only one member of the Amaranth family qualifies as a wildflower rather than a weed. It is the Slender Snakecotton—another nice name—but it only grows in West Texas. Sorry.)
See you round the D.P.
