YARD WEEDS - ARE THEY BENEFICIAL?


CAN WE USE THEM EASTHETICALLY IN THE LANDSCAPE?
DO THEY HAVE MEDICINAL USES?


Although errantly assumed to compete with neighboring plants for food and moisture, some "weeds" provide the soil with nutrients, either directly or indirectly.For example, legumes, such as white clover, add nitrogen to the soil through the process of nitrogen fixation, where bacteria symbiotically living in their roots extract nitrogen from the atmosphere, making it accessible in the soil for its host, and any nearby plants.Others use deep tap roots to bring up nutrients and moisture from beyond the range of normal plants, so that the soil improves in quality over generations of that plant's presence.Weeds with strong, widespread roots also introduce organic matter to the earth in the form of those roots, turning hard, dense clay dirt into richer, more fertile soil.In fact, some common plants like tomatoes and corn will "piggyback" on nearby weeds, allowing their relatively weak root systems to go deeper than they could have alone.
THE FOLLOWING PICTURES OF WEEDS ARE LISTED ON THE BENEFICIAL WEED CHART BELOW:

Bashful MimosaMimosa pudicaground cover for tomatoes, pepperspredatory beetlesIts extract immobilizes the filariform larvae of Strongyloides stercoralis in less than one hour.[1] In contemporary medicine, Mimosa pudica is being investigated for its potential to yield novel chemotherapeutic compounds. It contains an alkaloid calledmimosine, which has been found to have potent antiproliferative and apoptotic effects.[2]Used as a natural ground cover in agriculture
Caper SpurgeEuphorbia lathyrisMolesUsed in folk medicine as an antiseptic and purgativeMany domesticated animals can eat it, although it's poisonous to humans. Beneficial weeds can accomplish a number of roles in the garden or yard, including fertilizing the soil, increasing moisture, acting as shelter or living mulch, repelling pests, attracting beneficial insects, or serving as food or other resources for human beings.
Clover
TrifoliumBrassica (cabbage and cousins like broccoli and cauliflower), corn, cucurbits (cucumber, squash, melons, gourds) -- Along with fertilizing the soil, this plant provides a humid microclimate that benefits many plants by stabilizing their moistureRabbitsThis legume is a high-protein source of food, but generally only eaten in survival situationsNightshades(tomato, pepper, eggplants)This legume hosts nitrogen-fixing bacteria in its roots, and therefore fertilizes the soil for neighboring plants. It is also used as a fallow plant by some farmers, and is a very popular fodder plant.
CockleburXanthiumGrasses and grainsArmy wormsIs used in Chinese medicinePoisonous to some lifestockAlso used for yellow dye

DandelionTaraxacumVarious grains, tomato plantsHoneybeesArmywormsIn season, leaves and flowers are edibleUsed as a diuretic in herbal medicineTap root breaks up hardened soil and brings up nutrients from deep down, benefiting plants with weaker or shallower roots without competing with them.

Ground IvyGlechoma hederaceaTomatoes, peppers, cucumbers and relatives (squash, melons), broccoli, brussels sprouts, cauliflowercabbage worms, cucumber worms and beetles, tomato horn worms, othersCan be used in herb tea, high in vitamin CUsed in the traditional medicine of Europe going back thousands of years. Inflammation of the eyes, tinnitus, a diuretic, astringent, tonic and gentle stimulant. See here for more.This wild mint makes a good ground cover companion plant, creating a humid microclimate, covering up nearby plant scents, and distracting pests from companion crops.

HorsenettleSolanum carolinensePredatory beetlesThe berries of this fruit may be edible when cookedRipe fruit, when cooked, is used by herbalists as a diuretic and sedative
MilkweedAsclepiasCorn, basil, potatoesPredatory waspsWirewormsFolk remedy for warts, sap reduces poison ivy symptomsCan be used as a more effective insulator than goose down. Emits a chemical that breaks up hard soil, allowing nearby plants to develop healthier root systems. Basil repels some insects that attack milkweed.

NettleUrtica dioicabroccoli, tomato [1]Valarian, mint, fennelbeesDespite its "sting", young plant parts are edible, as is much of the plant when blanched or otherwise prepared. Also makes a nutritious herb teaOne of the most-used plants in herbal medicine, with a long list of benefits[2]Also once grown as a crop for its fiber. Its juice was once used in the place of rennet in cheese-making. It was also a source of "green" for dye. It can still be used as a high-protein additive in animal feed, once dried.

PurslanePortulaca oleraceacorn, solanums like tomatoes and peppersPurslane is eaten throughout much of Europe and Mexico. It contains more Omega-3 fatty acids than any other leafy vegetable plant. It can be eaten in salad, stir-fried, or cooked like spinach. berries can be eaten like capersIn Traditional Chinese Medicine, it is used to treat infections or bleeding of the genito-urinary tract as well as dysentery. It may also be applied topically to relieve sores and insect or snake bites on the skin.Dill, parsnip, radishBreaks up hard soil and hardpan, brings nutrients and water up from deeper than crops can reach, provides healthy ground cover, stabilizing soil moisture

This is known as the Triangle of U.
Wild RoseRosaStrawberries, grapes, rosesRodents and deerTraps Japanese beetlesRose hips can be used in herb teaSame medicinal benefits as domesticated roseThis includes the feralmultiflora rose, brought to the US [4] both for use as root stock for domesticated roses, and as a "natural fence" for lifestock. In the mid 20th century miles of multiflora rose hedge were planted in sequence.

Wild VetchVicia americanaPepper and tomato plants, brassica (cabbage, mustard, broccoli), other plants needing high nitrogenProvides ground cover for predatory beetlesThis legume fixes nitrogen, allow it to grow in a tomato garden only until time to plant, as ground cover. But can be left growing among brassica for additional nitrogen and microclimate
