Rudbeckia amplexicaulis aka Clasping Leaf Coneflower

Taxonomy

Rudbeckia amplexicaulis, also known as Clasping Coneflower, is a monotypic genus native to North America. This annual plant grows up to 1 meter tall, with simple or branched stems and oval leaves measuring 5-10 cm long and 2-4 cm broad. The daisy-like inflorescences produce yellow to yellowish-purple florets, with the distinguishing feature of chaff subtending the ray flowers. Alongside Echinacea, Rudbeckia, and Ratibida, it belongs to the coneflower family in the Asteraceae flowering plant family. This plant has gained the Royal Horticultural Society's Award of Garden Merit in the UK. In cultivation, Clasping Coneflower thrives in direct light, preferably within 1 foot of a window, and requires regular watering. It prefers well-draining soil and does not usually require added fertilizers if repotted when it doubles in size.

How to care for Clasping Leaf Coneflower

Water

Clasping Leaf Coneflower should be watered regularly, allowing the soil to dry out between waterings.

Soil

Clasping Leaf Coneflower 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

Clasping Leaf Coneflower 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 Clasping Leaved Coneflower.

Toxicity

No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.

Fertilizer

Once the Clasping Leaf Coneflower 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.
