Its strong central stem is often red or reddish-purple in color, and there is very little branching except for flowering stems towards the top half of the plant. Its leaves are oblong and dark green with a sandpapery texture due to tiny stiff hairs. The upper stems terminate into individual or small clusters of bright yellow flowers.

HELIANTHUS (SUNFLOWER):

There are about 70 species of Helianthus plants that consist of annual and perennial flowering plants, commonly called sunflowers, and are native to North, Central, and South America. They are usually tall plants with disc flowers that for the majority of species are yellow, but there are some species with reddish lobes. Before blooming, young sunflower heads follow the sun across the sky and at night they reorient themselves to face East for the sunrise. Once the flower heads are mature and fully open, they generally stop moving with the sun and remain facing East.
