When you are new to gardening, or you see broadleaf weeds with yellow or white flowers. It can be easy to mistake them, depending on the area of your garden they grow.
Some common weeds are easy to distinguish and control, although others that root in your lawn and garden can be harder to deal with.
An invasive weed doesn’t need a large root system, and thus this allows them to grow faster as they spread around your garden.
It can be the appearance that confuses many gardeners, as with blue flowers and green leaves, their appearance is more like flowers than a weed. (Read How to Kill Weeds Permanently)
To help you understand which, you can use this guide to help prevent a flowering weed from confusing you, and flowering before you can deal with it.
By the end, you can see some of the more common flowering weeds you can find and how using an herbicide, thick mulch around your flowers to stop weed growth and help prevent the roots of the weeds from taking hold and taking over your lawns.
How Do I Identify Weeds in My Yard?
The term “Weed” isn’t a botanical such as ones like “deciduous” or “perennial,” which are words that mean something specific.
The name “Weed” implies a more subjective definition but may generally be viewed as undesirable plants located in the incorrect place.
Weeds are generally wild flowers or plants with insignificant flowers or unsightly foliage, unlike the more attractive wild flowers or cultivated and striking flowers we grow in our gardens.
Interestingly, many cultivated flowers seed themselves or propagate in some other manner so quickly within our flowerbeds that they become a plague at some time and may even earn the title of “weeds” in their own right.
In the sense of the word, weeds are unwanted plants in the wrong place.
What Are the White Flower Weeds Called?
White clover can be loved or hated by gardeners. For many who don’t intentionally plant white clover, it is good to know how you can control white clover in your lawn or garden beds.
It can be a challenge to get rid of white clover once it establishes itself, though, with the right tools and some patience, you can do it. White clover is a perennial weed, which grows low to the ground. (Read Best Time to Spray Lawn for Weeds)
It can grow in numerous areas, yet you typically find it on your lawn. The larger the lawn, the more chance you have because competition from grass can be weakened.
Leaves of the white clover emerge in sets of 3, and each leaflet is tear-shaped with reddish stripes across them. White clover flowers are spiky and come with brownish-green centers.
You see this clover growing in a creeping way and develop roots whenever stem nodes can touch bare soil. You can find this weed acts as a living mulch, as it was used years ago.
If you want to get rid of this clover, it grows in clumps, so you can hand pull it to remove it. Though if your lawn is extensive, you may need an herbicide. The issue here is that effective herbicides are non-selective and will kill anything around them and should be used as a last resort.
What are the Purple Weeds Called?
The two common broadleaf weeds, Purple deadnettle, and henbit are often confused with each other, significantly, if you add Creeping Charlie’s identification.
Both henbit and Purple deadnettle weeds are cool-season annuals where they start life in the fall with seed germination and flower in the spring. (Read Straight vs Curved Trimmer Guide)
Toward the warmer weather of summer, these weeds begin to die back. The scientific name for the purple deadnettle is Lamium purpureum, while Lamium amplexicaule is for henbit.
Both belong to the mint family, have square stems, and sparsely hairy oval to egg-shaped leaves. Each also has small purple flowers you see during the spring. Typically not an issue for farmers, it’s challenging to deal with this invasive plant in landscapes and turfgrass.
Using pre-emergent herbicide, you target the spring seeds of any summer annuals; any winter annuals like these weeds will not be affected and reappear each spring.
As mentioned, Creeping Charlie is another weed, also in the mint family (also known as ground ivy).
Since it is a mint, it portrays some of the same characteristics until you inspect closer. Henbit and deadnettle are winter annuals that flower in the early spring and die back in the late spring.
Creeping Charlie is a perennial and flowers in late spring. The purple flowers are kidney-shaped leaves that are toothed. You find these purple flowering weeds; the grass of your lawn is where they spread and creep where they try to take control in your garden.
Another type you can find is the Wild Violet, and the gardener’s opinions are divided. To some, it’s a weed in their garden, and others a dainty wildflower plant they don’t need to control.
Either way, you ought to know, violets are often seen as shy, although this one perennial bloomer spreads quickly and long as they use underground stems and seeds.
Once on your lawn, it can adapt to low mower heights, and thus being able to avoid the blades. Violets love moist, shade areas, although once mature, they are drought tolerant. To get rid of them, you need to pull a lot by hand and use good targeted herbicides.
What Flowers are Actually Weeds?
Purslane (Portulaca oleracea)
Purslane is a ground-hugging weed with fleshy leaves and likes to live in dry, sandy soil.
While it is still a weed, it happens to be edible and one of the most nutritious plants you can find. Purslane is a favorite among the edible weeds, and if you like juicy foods, this succulent offers juice in every bite.
As a lawn weed, purslane produces a high number of seeds. To control it, you will need a chemical control regimen, though both types. A pre-emergent herbicide and also a post-emergent herbicide will be required.
If you try to pull the weed, make sure you get it all, as even the smallest remaining piece can lead to new growth.
Dandelions (Taraxacum officinale and Teracacum erythrospermum)
You may know these better by the fluffy, white ball they have when seeding that sits on the top of the stem. However, before this, they look like a regular bright yellow flower with funny shaped leaves.
You’ll see them growing well in spring and fall, and the plant grows quite a few inches tall.
The common dandelion came from the aster family. It arrived in North America areas from European areas, where it quickly became a wildflower and grows as a common lawn weed with yellow flowers and wide green leaves.
Unlike other weeds, dandelion is a perennial and grows best with a long deep taproot a few inches deep, making it a challenge to eradicate from gardens.
One of the best ways to stop a broadleaf dandelion pushing up through your lawn is by having healthy and thick grass or a couple of inches thick mulch in your flower bed areas.
At mowing time, you may cut the top yellow flower, but it is best to remove all the long root as well.
Dandelions can be pulled by hand and killed with vinegar. Though you can use herbicides that target these, keep them from doing too much damage to lawns.
Bindweed (Convolvulus arvensis)
A member of the Morning glory family, Bindweed, is a climber and like to wrap well around other plants. It can grow from 4 feet to ten feet tall, depending on support. Aside from this, it produces small blue or white trumpet-shaped Morning Glory-like blooms and pointy leaves.
Once it establishes itself, it’s difficult to eliminate after this type will wrap and intertwine with other plants. It is difficult to remove as any small root pieces will re-grow.
It grows fast and wide rather than deep in hot weather and can quickly overtake a lawn if it spreads wide across the ground. It is a perennial, although it grows mainly in spring and summer.
Chickweed: (Stellaria media)
This annual weed is very low growing and won’t bother some tall plants too much. It has an unsightly appearance once spreading open ground toward lawns. It is easy to remove as it is found a couple of inches high, and you can pull it quickly rather than try mowing it.
This annual weed can be found in shady areas that offer moist, fertile soil, though it can cope with dry areas.
Chickweed forms a low crown of stems that spread. In planting beds, stems crawl through your perennials and annuals and will show up as far as 12 inches to 18 inches from the plant’s crown. (Read How to Get Rid of Chickweed)
Once in a lawn, it usually appears in thin grass that has heavy, moist soil. If hand-pulling, you need to get the plants before they seed, as they can produce numbers up to 800 per plant.
If you have a heavy infestation, you need to make sure and check for herbicides listing chickweed. You can also find other perennial types of this with the same appearance, yet they produce more via seed, stem, or root pieces.
The Black Nightshade is a broadleaf annual you can find in lawns or hardens that comprise rich soil. Such weeds are described as climbing or bush plants and produce white and sometimes purple flowers.
You can find them producing green leaves and red or purple fruits.
Should you have found these in your garden, you need to take control and get rid of this plant from your garden, as they are considered poisonous, and you need to prevent children from being drawn to the appearance of the red fruits.
The plants grow up to 2 feet wide, and 2 feet tall; and are as happy in the shade as in the sun. To prevent these, wear gloves to remove them, pulling by hand or remove them with a post-emergence herbicide. (Read Do Roses Need Full Sun)
While the above mentions a few weeds you can find in gardens, it is by no way an extensive list. Depending on the type of weed, you can find them growing to a few feet tall without assistance.
Some of the plants and leaves look nice, yet these plants can dramatically impact the health of your garden once they start growing.
