6 Weeds That Has Red Flowers

Many weeds can pop up in a garden, but the ones with the most eye-catching blooms are the red ones. They are still weeds, so remember to pluck them out. List of weeds with red flowers are listed below:

1. Red Witchweed

Scientific name: Striga asiatica

The plant’s native range includes parts of Asia & Africa. The US and Australia are just some places where this plant is under cultivation.

Plants of this sort may survive and thrive on the grasses of other species. The green, furry stems and the thin, inch-long leaves make this plant easy to notice since it may reach a height of 12 inches.

Tiny red blooms, sometimes occasionally purple/yellow, bloom on this shrub. In some instances, the flower’s hue may vary.

Because of its rapid proliferation, difficulty in management, and potential for severe damage to crops and cattle, this plant should not be introduced.


These weeds can be managed by employing the following strategies:

  • Weeding by hand and with a hoe.
  • Blending grain and legume production.
  • Rotating cereal crops with “trap crops.”
  • Through the use of urea and urea-based inorganic N fertilizers and animal manure.

2. Common Poppy

Scientific name: Papaver rhoeas

Broadleaf weed is known for having the poppy in it. It lives in places with grass and pastures. It does best in warm, dry areas and needs soil that drains well.

 In the northern hemisphere, weeds often bloom as spring goes on.

The poppy plant has thick hair and can make around 400 blooms. Each flower has four petals that overlap and one black center. The wind spreads the seeds of these weeds inside capsules that look like eggs.

It’s not unusual to plant it and have to wait eight years or more for it to grow. After the seeds sprout, it takes around four weeks for the flowers to mature and fall off.


Hand and mechanical weeding, host plant resistance, trap crops, heavy nitrogen (N) fertilizer application, herbicide application, land fallowing, crop rotations, mixed cropping, or inter-cropping with non-hosts are some of the many control options available to mitigate crimson poppy damage in vulnerable crops.

3. Crimson Clover

Scientific name: Trifolium incarnatum

There are a few other names for the crimson clover plant, but the most frequent ones are Italian and red. This crop is maintained year-round to provide a steady feed supply for livestock during the winter.

The deep roots of the red clover make the soil more stable and healthy. The 8- to 20-inch flower cluster has 40 to 50 individual flowers at its tallest point. The part that connects the stem to the leaves is very long.


Cultural measures, such as regular grass mowing and irrigation, can help reduce the spread of red clover. The seeds can be dispersed to other parts of your lawn and landscaping if you remove them physically (i.e., by “weed plucking”).

Glyphosate, a component of several commercially available herbicides, is effective against red clover weeds. Be cautious about letting this herbicide since it might potentially harm non-target plants.

Professional lawn service will use a carefully chosen herbicide to eradicate the infestation, killing everything from the leaves to the roots while protecting the desired plants in the area.

4. Red Sorrel

Scientific name: Rumex acetosella

Sour weed & field sorrel are other names for red sorrel. That species made its way over the Atlantic from Europe and the British Islands to the United States. That’s a huge deal here.

An invasive plant, red sorrel spreads rapidly through rhizomes and seeds. Unless we get rid of the weeds’ rhizomes and roots, the seeds might lie dormant in the soil for up to 25 years before sprouting.

The plant’s leaves are distinctive due to their tiny size, arrowhead form, and rosette arrangement. These are edible and have a sour flavor similar to apples or lemons. The weed has significant amounts of oxalic acid, which is in great demand. Contrarily, grazing animals pose little danger to humans or other animals.


The garden should be inspected frequently so that its expansion can be halted. As you move from one part of the lawn to another, wipe down your gardening tool.

5. Tropical Milkweed

Scientific name: Asclepias curassavica

These include red-head cotton bush or blood flower, among others. It’s also known as crimson milkweed or butterfly plant in Mexico. The plant is a common ornamental in its native Central America. It is common in fields, meadows, and roadsides despite being cultivated as an attractive plant.

In this case, the weed is a beautiful plant. Its vibrant orange hue stands out with a crimson bloom. It looks like more petals that face the center of the flower.

However, tropical milkweeds continue to maintain their green color throughout the winter as the plant accumulates more and more OE.


If you decide that control is essential, you may cut back the contaminated stems and drown them or flick them off the plant into a container of rubbing alcohol.

Or To prevent monarch butterflies from establishing winter breeding colonies, milkweed should be cut down to a height of approximately 6 inches throughout the autumn and winter.

Reducing the milkweed’s size may also assist in getting rid of any OE spores that could be lingering on the plant.

Scarlet Pimpernel plants have thick stalks that are cut in a square shape. The leaves on the stems of these flowers are oval and light green. They grow in pairs.

Scarlet pimpernel plants are a problem on lawns that aren’t taken care of because they need to be taken care of during the day. When night comes, the petals close. Weeds can be killed by mowing regularly. You can kill this weed with weed killer, but you’ll have to do it again in six weeks.

This common weed grows in fields, gardens, lawns, and along the edges of ponds and other bodies of water. It has been proven that it is poisonous. People and animals risk getting sick or dying if they eat this substance.


You merely have to mow your grass regularly to get rid of this plant, which only grows in unattended spaces. It can be eradicated with a specific weed killer, but you may need to use it again in about six weeks.
