Ceratophyllum demersum, commonly known as hornwort (a common name shared with the unrelated Anthocerotophyta), rigid hornwort, [2] coontail, or coon's tail, [3] is a species of flowering plant in the genus Ceratophyllum.
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, [1] and grass kelp. [2] Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha .
The flowers are mostly visited by bumblebees; [2] when the flowers drop off and tiny bright green seed pods 10–20 mm long, start to form. [3] Cow vetch is very similar to hairy vetch (Vicia villosa), but is distinguished from the latter by its smooth stem. Legumes and seeds. The seed pods are 2 cm long and contain 6 to 8 seeds. [4]
Witchweeds are characterized by bright-green stems and leaves and small, brightly colored and attractive flowers. [5] They are obligate hemiparasites of roots and require a living host for germination and initial development, though they can then survive on their own. [6] The number of species is uncertain, but may exceed 40 by some counts. [6] [7]
One major problem with Z. japonica in recreational landscapes is its seeding in spring, which is aesthetically unacceptable requiring additional maintenance costs. [ 13 ] [ 14 ] Brosnan et al. , 2012 suppresses seedhead development with imidazolinones without killing the grass, and Patton et al. , 2018 achieves the same result with ethephon ...
Complete removal of the rhizomes or poisoning, (usually before flowers are matured), is the only certain way of controlling the plant if it is considered a weed. [8] When Hedychium gardnerianum is particularly virulent, annual follow up is required for some years to prevent re-infestation.
