Datura

Datura, also known as thorn apple or jimsonweed, is a fast-growing weed found in gardens, paddocks, and along roadsides across Australia. You can spot datura by its large, trumpet-shaped flowers that are usually white or purple, and its spiky, round seed capsules. The leaves are broad with wavy or toothed edges and give off a strong smell when crushed. All parts of datura are highly poisonous to people, pets, and livestock, so it’s important to control this weed as soon as you see it

Datura is a fast-growing weed that stands out because of its bold features, strong smell, and ability to spread quickly.

Leaves

To begin with, the leaves are broad, green, and often have wavy or toothed edges. They grow one at a time along the stem and give off a strong smell when crushed.

Flowers

Next, the flowers are large, trumpet-shaped, and usually white or purple. They bloom in the evening and often release a strong, sweet scent, making them easy to notice.

Fruit

As the plant matures, it produces spiky, round fruit capsules filled with many black seeds. When ripe, these capsules split open and drop the seeds onto the ground, helping the plant spread.

Growth Habit

Finally, datura grows as a bushy plant, often reaching up to 2 metres tall. Its thick, hollow stems add to its standout look and make it easy to spot in paddocks or along road

Datura can spread quickly and cause problems in gardens, paddocks, and bushland. However, by acting early and using a few easy methods, you can keep it under control before it takes over.

Remove Young Plants Early

To begin with, pull out young datura plants by hand before they flower and set seed. Make sure to wear gloves, as the plant is toxic. Try to get the whole root to stop the weed from growing back.

Use Mulch in Gardens

Next, spread a thick layer of mulch in garden beds and bare spots. Mulch blocks sunlight, which helps stop datura seeds from sprouting. It also helps your soil stay moist and healthy for other plants.

Mow or Slash Larger Plants

If datura is growing in large areas, mow or slash the plants before they flower. This stops them from setting seed. Be sure to collect and safely get rid of any cut plant parts, as they remain toxic.

Apply Selective Herbicides

For bigger infestations, use a selective herbicide that targets broadleaf weeds. Choose products with active ingredients like 2,4-D or dicamba. Follow the label closely and spray when the datura is still young and growing—usually in spring or early summer.
