Spanish Needles Bidens pilosa 100 Seeds

Bidens pilosa is a herbaceous plant that typically grows as an annual or short-lived perennial. Here's a more detailed description of its key features:

Size and Growth Habit:

Bidens pilosa can grow to a height of 0.3 to 1.5 meters (1 to 5 feet), depending on the growing conditions.

It has an erect, branching habit with a fairly bushy appearance.

Leaves:

The leaves are alternate, simple, and typically 5–15 cm long.

They are often deeply lobed with jagged edges, and their shape can vary (somewhat ovate to lance-shaped).

The leaves have a rough, hairy texture.

Flowers:

The flowers are bright yellow and consist of numerous small, tubular florets arranged in a composite head.

Each flower head typically has 5 (sometimes 4 or 6) petal-like ray florets that surround a cluster of tiny disc florets in the center.

These flowers are quite distinctive and are usually found in clusters.

Fruits and Seeds:

The plant produces small, dark brown or black seeds that are often described as "bur-like."

The seeds are equipped with barbed hooks, which help them attach to animals, clothing, or anything that can carry them over distances, facilitating seed dispersal.

Habitat:

Bidens pilosa is adaptable and can grow in a wide range of environments, including disturbed soils, roadsides, forests, and agricultural fields.

It thrives in tropical and subtropical regions but can also be found in temperate areas.
