The Weather Prophet Plant – Dimorphotheca Pluvialis

Plants have always fascinated humans with their diverse forms, colors, and unique adaptations. One such remarkable plant is the Dimorphotheca pluvialis, commonly known as the Weather Prophet. This South African native plant has garnered attention for its intriguing behavior of opening and closing its flowers in response to changes in weather conditions. In this blog post, we will explore the fascinating characteristics of the Weather Prophet plant, its cultural uses, care requirements, common diseases, and pest management strategies.

What is Dimorphotheca Pluvialis?

The Dimorphotheca pluvialis, also known as the Weather Prophet or South African daisy, is a species of flowering plant in the Asteraceae family. This plant is renowned for its distinct ability to predict changes in weather by opening its flowers on sunny days and closing them when overcast or rainy weather is approaching. Its sensitivity to environmental conditions makes it a unique and captivating addition to gardens and landscapes.

Key Takeaways – Weather Prophet (Dimorphotheca Pluvialis)

  • Dimorphotheca pluvialis, also known as the Weather Prophet, is a South African daisy with the unique ability to open and close its flowers in response to weather changes.
  • Its drought-resistant nature makes it an ideal choice for arid and semi-arid regions.
  • Understanding the cultural requirements, water, sunlight, fertilizer, soil, pruning, propagation, and pest management strategies is essential for successfully growing and maintaining the Weather Prophet plant.



The Weather Prophet plant holds cultural significance beyond its unique weather-predicting ability. It is commonly cultivated for ornamental purposes in gardens, parks, and landscapes. Its vibrant, daisy-like flowers add a splash of color to the surroundings, making it a popular choice for decorative landscapes and floral arrangements.


Dimorphotheca pluvialis, being a drought-resistant plant, exhibits tolerance to dry conditions once established. However, during its initial establishment phase, regular watering is essential to promote healthy growth and blooming. It is crucial to avoid over-watering, as excessive moisture can lead to root rot and other issues. Providing well-drained soil and watering when the top inch of the soil feels dry is recommended for the optimal growth of the Weather Prophet plant.


The Weather Prophet plant thrives in full sunlight and requires at least 6-8 hours of direct sunlight per day for optimal growth and flowering. It is essential to provide a suitable location with ample sunlight exposure to ensure the plant’s health and vigor.


When it comes to fertilization, the Weather Prophet plant benefits from a balanced, water-soluble fertilizer applied during the growing season. A general-purpose fertilizer with equal proportions of nitrogen, phosphorus, and potassium can be applied every 4-6 weeks to support healthy foliage and flower production. It is important to follow the recommended dosage and application guidelines to prevent fertilizer burn and other related issues.


Dimorphotheca pluvialis thrives in well-drained, moderately fertile soil. A loamy or sandy soil with good drainage properties is ideal for this plant. Amending the soil with organic matter such as compost or aged manure can improve its texture and nutrient-holding capacity, promoting healthy root development and overall growth of the Weather Prophet plant.


Pruning plays a crucial role in maintaining the health and appearance of the Weather Prophet plant. Regular deadheading of faded flowers not only enhances the plant’s aesthetic appeal but also encourages continuous blooming. Additionally, the removal of damaged or diseased foliage aids in preventing the spread of diseases and promotes better air circulation within the plant canopy.


The propagation of Dimorphotheca pluvialis can be achieved through methods such as seed sowing and division. Seeds can be sown directly into the garden soil after the last frost date or started indoors before transplanting. Division of mature clumps can also be performed in early spring to create new plants. Both methods require suitable growing conditions and regular monitoring to ensure successful establishment and growth of propagated Weather Prophet plants.

Container Popularity

The compact growth habit and ornamental value of the Weather Prophet plant make it a popular choice for container gardening. Its ability to thrive in containers enables gardeners to enjoy its beauty on patios, balconies, and other confined spaces. Selecting a well-draining potting mix and providing adequate sunlight and water are essential for container-grown Dimorphotheca pluvialis plants.

Container Common Diseases

In container gardening, plants are susceptible to specific diseases and issues related to potting mix, drainage, and overall container conditions. Some common diseases that may affect Weather Prophet plants in containers include:

  • Root Rot: Over-watering and poor drainage in containers can lead to root rot, causing the plant to wilt and eventually die if left untreated.
  • Powdery Mildew: Humid and poorly ventilated conditions in containers can promote the development of powdery mildew on the foliage of Dimorphotheca pluvialis plants.

Disease Diagnosis

Prompt diagnosis and treatment of diseases are crucial for preventing the spread of infections and ensuring the long-term health of the Weather Prophet plant. Regular monitoring for symptoms such as wilting, discoloration, or abnormal growth can aid in early disease detection. If signs of disease are noticed, appropriate measures, such as adjusting watering practices or applying suitable fungicidal treatments, should be implemented to address the issue.

Common Pests

While the Weather Prophet plant is relatively resistant to pest infestations, certain insects and pests may pose a threat to its health. Common pests that may affect Dimorphotheca pluvialis include:

  • Aphids: These small, sap-sucking insects can cause damage to the foliage and flowers of the plant, leading to stunted growth and deformation.
  • Spider Mites: These tiny pests thrive in dry conditions and can cause stippling and discoloration of the leaves, compromising the plant’s overall health.

Botanist’s Tips

To ensure the successful cultivation of Dimorphotheca pluvialis and the optimal expression of its unique weather-predicting behavior, the following tips are recommended:

  • Provide well-drained soil and suitable growing conditions to prevent waterlogging and related issues.
  • Monitor the plant for changes in flowering patterns and use it as a natural indicator of impending weather conditions.
  • Implement proactive pest management strategies to protect the plant from potential infestations and diseases.
