Common Name: Curly Dock.
Scientific Name: Rumex Crispus.
What to look for? Curly Dock is a tall, erect, weedy plant. In the spring, it consists of a rosette of green, oblong, basal leaves. During summer, a tall, branchless stalk bolts from this rosette. Atop each stem is a terminal cluster of small, yellowish- or reddish-green flowers. Each towering cluster has as many as twenty or more flowers. Each flower matures into a dry fruit that contains a single seed. The fruit and stems of Curly Dock become dark brown with maturity. The rather large seeds are dark brown and are distributed to some extent by wind or water while adhering to the membranous wings of the fruit. This plant spread by reseeding itself. The root system consists of a stout taproot.
Where can they be found at Carillon Stonegate Pond? Curly Docks pop up sporadically around our meadow areas at Carillon Stonegate Pond and scattered in the restored prairie at Stonegate Park.
How big are they? The Curly Dock generally grows from one (1) to three (3) feet tall. The oblong leaves are approximately six (6) inches long and two (2) inches across. The two (2) inch long flower clusters have tiny, individual flowers that no more than one-eighth of an inch in length.
Where do they grow and thrive? Curly Dock is a native of Europe. Curly Dock can be found across the U.S. as well as the globe. It is considered a weed in more than 40 countries. Curly Dock is common in pastures, meadows, prairies, orchards, lawns, and home gardens as well as along roadsides and waste areas.
When do they bloom? The blooming period of the Curly Dock occurs during the summer and lasts about a month.
Do birds, insects or other wildlife associate with this plant? Because the flowers are cross-pollinated by wind, they attract very few insect pollinators. Various birds eat the seeds of the Curly Dock, including Song Sparrows and Red-winged Blackbirds. The foliage of these plants is bitter and avoided by other animals.
