Vernonia fasciculata aka Common Ironweed

Taxonomy

Vernonia fasciculata, also known as the smooth ironweed, common ironweed, or prairie ironweed, is a clump-forming perennial plant in the Asteraceae family. Native to Manitoba in Canada and the north-central USA, this species thrives in areas with moist soils and prairies. Growing up to 1.2m high, it features upright, smooth, leafy stems and lance-shaped, toothed leaves that are evenly spaced along the stem. In the autumn, it produces tight clusters of small violet flowers on branched stems above the foliage, which are later followed by rusty red seedheads. Additionally, this rare houseplant, Prairie Ironweed, is easy to grow and requires regular watering. It thrives in long-lasting, direct light and should be placed within one foot of a window. Prairie Ironweed prefers well-draining soil and does not usually require additional fertilizers if repotted each time it doubles in size. Native to South-Central Canada to the Central and Eastern United States, it belongs to the Vernonia genus.

How to care for Common Ironweed

Difficulty

Caring for Common Ironweed is a breeze, as it is highly adaptable and forgiving to minor neglect.

Water

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

Soil

Common Ironweed 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

Common Ironweed requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Prairie Ironweed is always in the right place to thrive.

Toxicity

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

Fertilizer

Repotting the Common Ironweed should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

Growth-pattern

New growth will sprout from the top of the Common Ironweed as it grows vertically.
