Family: Asteraceae
Common name: False sunflower, Smooth oxeye, Early sunflower, Eastern ox-eye, Rough oxeye, Ox-eye daisy, Eastern sunflower-everlasting, Heliopsis, Ox-eye, Oxeye sunflower

False sunflower is a dazzling perennial plant that is native to North America, gracing gardens with their bright yellow flowers, and their ability to attract pollinators. These plants can grow to a height of 1 to 1.5 meters, with upright stems that are adorned with lance-shaped leaves. They have a bushy growing habit, forming small clumps, making them an excellent choice as border plants, or for hanging baskets.

The leaves of False sunflower plants are simple, opposite, and finely serrated along the edges, about 7 to 14 cm in length. These lush, dark green leaves provide a lovely contrast to the vibrant yellow flowers that bloom in abundance like lovely bouquets during spring and summer.

These daisy-like flowers have a striking resemblance to Sunflowers or Helianthus annuus, giving the plant its name. The flowers can grow to a diameter of about 5 to 7 cm with numerous tiny disk florets and a few dark yellow ray florets or actual petals that are 2-3 cm long.

False sunflower plants blooms can bring a riot of color to your home garden, in addition to being magnets for insects, butterflies, and ants that help pollinate these as well as other plants.

After the flowers fade, False sunflower plants produce seed heads resembling small achene fruits. These seeds are light and can be carried by the wind, allowing the plant to self-seed in favorable conditions. While the fruits are not typically a prominent feature, they play a crucial role in the plant’s reproductive cycle.

False sunflower plants make an excellent choice for amateur gardeners since they are easy to grow and maintain. They are seasonal, producing flowers during the season and drying out once the winter sets in.

Most plants will produce enough seeds to grow a new batch of plants once the conditions are better. False sunflower plants need good 4-6 hours of direct sunlight for good blooming, along with sufficient watering and fertilization. All plants that bloom well are heavy feeders, thriving well when they are taken care of.

False sunflower plants can be trimmed to remove spent flowers, encouraging the plant to produce more blooms. This process also prevents the plant from diverting energy into seed production, allowing it to focus on new flower development.

False sunflower plants can become very top-heavy once they bloom fully, requiring staking or support to prevent the plant from leaning or tipping over.

These plants have some medicinal uses in reducing inflammation, treating wounds and minor skin irritations, bacterial infections, and fever.

Propagation is very effectively done through seeds that can be stored once they are fully dry, and planted in early spring. They can also be propagated by dividing mature plants and planting them separately to allow each section to grow into a full plant.
