Buttercup Bush Senna corymbosa
ABOUT
Senna corymbosa, commonly known as Buttercup Bush, is a flowering plant with a bushy appearance, characterized by its vibrant and decorative look. The plant features compound leaves that are medium to dark green, giving it a lush and dense foliage. Each leaf is composed of several small, elliptical leaflets that are arranged in pairs along the central stem of the leaf. The Buttercup Bush is particularly noted for its striking yellow flowers that bloom in clusters at the ends of the branches. These flowers are typically bright and showy with five petals, creating a cup-like shape that is appealing to various pollinators. The blossoms have a subtle, sweet fragrance which can attract bees and butterflies to the garden. Following the flowering period, the Buttercup Bush produces seed pods. These pods are elongated and slightly curved, starting out green and maturing to a dark brown color as they dry. The seeds inside are small and can be dispersed by wind or passing animals, which aids in the propagation of the plant. The overall appearance of the Buttercup Bush is somewhat rounded and it can become quite dense, making it an excellent choice for gardeners looking to add a burst of color and texture to their landscape. The plant can adapt to a variety of soil types but prefers a sunny location where it can flourish and produce its signature yellow blossoms.

- Toxicity
To humans
Buttercup bush (Senna corymbosa) contains anthraquinones, which are known to have a laxative effect, and saponins, which can be toxic in higher quantities. If ingested, parts of the plant can cause gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea. In some individuals, particularly children or those with sensitive systems, ingesting significant quantities might lead to more serious conditions such as electrolyte imbalances or dehydration due to prolonged diarrhea. It is therefore advised to avoid consumption of this plant and keep it out of reach of children.
To pets
Buttercup bush (Senna corymbosa) is toxic to pets due to its content of anthraquinones and saponins. If ingested by animals such as dogs or cats, it can cause symptoms similar to those in humans, including vomiting, diarrhea, abdominal pain, and potential lethargy. With pets, even small amounts can be harmful, and if symptoms are observed, immediate veterinary attention is recommended to prevent dehydration and to provide symptomatic relief and supportive care. It is important for pet owners to be cautious and prevent their pets from accessing or consuming the plant.

- Water
The butterfly bush, as Senna corymbosa is commonly known, prefers to have its soil kept moderately moist, but it is also drought-tolerant once established. It's best to water this plant deeply once a week, allowing water to reach deep into the root zone. During the growing season, especially in the absence of rainfall, this might translate to about 1 to 1.5 gallons depending on the size of the plant and the weather conditions. Reduce watering in the winter months when the plant is not actively growing. Always ensure the plant is not sitting in waterlogged soil to prevent root rot.
- Light
The butterfly bush thrives best in full sunlight, which means it should receive at least 6 to 8 hours of direct sunlight each day. Plant it in a location where it can enjoy uninterrupted sun throughout the day for optimal growth and blooming. Do remember that while it tolerates partial shade, too much shade can lead to reduced flowering and a leggy growth habit.
- Temperature
The butterfly bush is hardy and adaptable, but it performs best in temperatures ranging from 60 to 80 degrees Fahrenheit. It can tolerate minimum temperatures down to around 20 degrees Fahrenheit, but frost can damage the plant, so it's preferable to protect it in colder climates. Optimal growth will occur when the temperature is consistently within this comfortable range.
- Pruning
Pruning the butterfly bush helps to maintain its shape, encourage bushier growth, and enhance blooming. Prune in late winter or early spring before new growth starts by cutting back the previous year's growth to about a foot from the ground. Regularly removing faded flowers can also promote continued blooming throughout the growing season.
- Cleaning
As needed
- Soil
The Argentine Senna thrives in well-draining soil with a pH ranging from slightly acidic to neutral (pH 6.0-7.5). A mix containing loamy soil, peat, sand, and perlite is ideal for optimal growth, ensuring good aeration and moisture retention.
- Repotting
Argentine Senna should be repotted every 2-3 years or when it outgrows its pot, which is usually noticeable when roots start to crowd. Spring is the best time for repotting this plant.
- Humidity & Misting
Argentine Senna does well in moderate humidity conditions and does not require high humidity to thrive. Consistent, average room humidity will support its growth adequately.
- Suitable locations
Indoor
Place Argentine Senna in a bright spot, avoiding direct sun.
Outdoor
Plant in full sun to partial shade, well-draining soil.
Hardiness zone
9-11 USDA
- Life cycle
Senna corymbosa, commonly known as Buttercup Bush, begins its life cycle with seed germination after dispersal, typically occurring in warm and moist conditions. As a fast-growing plant, the seedling quickly establishes itself and develops into a vegetative stage, forming a robust root system and foliage. Throughout its active growth phase, Senna corymbosa undergoes vegetative growth characterized by the expansion of its pinnate leaves and woody stems. The plant then enters the reproductive stage, producing attractive yellow flowers that attract pollinators for sexual reproduction, after which it sets seed within elongated seed pods. These seed pods eventually dry and split open, dispersing seeds into the surrounding environment, thereby completing the cycle. In ideal conditions, Senna corymbosa can live for several years, repeating the flowering and seeding cycle annually.
- Propogation
Propogation time
Spring-Early Summer
Propogation: Butterfly Bush, also known as Senna corymbosa, is commonly propagated by seed. The most popular method of propagation is by collecting the seeds after the pods have matured and dried on the plant, which typically occurs in the fall. To propagate Butterfly Bush using seeds, one should first extract the seeds from the dry pods and then plant them in a well-draining soil mix. It's recommended to surface sow the seeds since they need light to germinate, and to keep the soil moist until germination, which usually takes 1 to 2 weeks at 70°F (21°C). After the seedlings have developed a couple of true leaves, they can be transplanted to individual pots or their final location in the garden.
