Helenium autumnale aka Sneezeweed

Taxonomy

Helenium autumnale, also known as common sneezeweed or large-flowered sneezeweed, is a North American species of flowering plants in the family Asteraceae. It is a compact, bushy, herbaceous perennial that grows up to 50cm tall. The plant has lance-shaped, toothed leaves and produces masses of flowers with slightly ruffled, orange-red petals and a deep red center that turn yellow as the florets open. Sneezeweed, a rare houseplant, is not difficult to grow and requires regular watering to thrive. It thrives best in long-lasting, direct light and should be placed less than 1 foot from a window. It prefers well-draining soil and does not usually require added fertilizers if repotted each time it doubles in size. Sneezeweed belongs to the Helenium genus and is native to North America.

How to care for Sneezeweed

Difficulty

Even if you don't have a green thumb, you can successfully care for Sneezeweed due to its easy-going nature.

Water

Sneezeweed should be watered regularly, allowing the soil to dry out between waterings.

Soil

Sneezeweed loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Sneezeweed thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Fall Sneezeweed.

Toxicity

Sneezeweed is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Fertilizer

Once the Sneezeweed has doubled in size or after a year has passed, it should be moved to a new pot. By replacing the soil with fresh potting soil containing all the vital nutrients, your plant will receive all the sustenance it needs, negating the requirement for fertilizer. It's important to remember that plants get their energy from the sun, not fertilizer.

Growth-pattern

The Sneezeweed displays clumping growth habits, with new shoots arising from the soil close to the parent plant.

Region of origin

Sneezeweed’s native range is Eastern N. America - Quebec to Florida, west to Manitoba and Arizona.
