Lifespan of Picked Osteospermum

How Long Will an Osteospermum Stay Alive Once Picked?

A common question that often arises among those who appreciate these stunning flowers is how long an Osteospermum can stay alive once it has been picked from the plant.

Osteospermum, also known as the African Daisy, is a popular flowering plant renowned for its vibrant, daisy-like blooms that come in a variety of colors. Originating from South Africa, this hardy plant has captured the hearts of gardeners and flower enthusiasts worldwide. As many desire to bring the beauty of African Daisies into their homes or use them in floral arrangements, understanding their lifespan and care requirements is crucial for ensuring the flowers remain fresh and vibrant for as long as possible.

Factors Affecting the Lifespan of Picked Osteospermum

Environmental Factors

  • Temperature: The longevity of picked Osteospermum flowers is highly influenced by the surrounding temperature. Maintain a cool environment, ideally between 50-60°F (10-15°C), to prevent the flowers from wilting prematurely. Avoid exposing the blooms to direct sunlight or heat sources such as radiators, which can cause dehydration and rapid deterioration.
  • Humidity: Moderate humidity levels, around 40-60%, help maintain the freshness of picked Osteospermum flowers. Low humidity can cause the petals to dry out and curl, whereas high humidity can promote mold growth. Use a humidifier or a shallow dish filled with water and pebbles placed near the arrangement to regulate humidity levels.


The lifespan of picked Osteospermum flowers is affected by temperature and humidity. Keep the environment cool (50-60°F or 10-15°C) and maintain moderate humidity levels (40-60%) to ensure freshness.

Flower Handling and Care

  • Cutting Technique: When cutting Osteospermum stems, use sharp, sterilized pruning shears or scissors to minimize damage and prevent the introduction of harmful pathogens. Clean cuts allow for better nutrient and water uptake, resulting in healthier and longer-lasting blooms.
  • Water Quality and Container Choice: Fill a clean vase or container with fresh, tepid water, as room temperature water is more readily absorbed by the stems. Avoid using metal containers that can react with flower preservatives, and opt for glass or plastic instead. Ensure that the container is the appropriate size to provide adequate support for the stems and prevent overcrowding.


Use sharp, sterilized tools when cutting stems for better nutrient uptake. Choose a suitable container, fill it with fresh water, and avoid overcrowding.

Tips to Extend the Life of Picked Osteospermum

  • Proper Cutting Techniques: To maximize water absorption, cut the stems at a 45-degree angle, ideally under running water or submerged in a bucket of water to minimize air embolisms. Remove any leaves that would be submerged in water, as they can rot and introduce bacteria. The best time to cut flowers is in the early morning or late afternoon when the plant is well-hydrated and the temperatures are cooler.
  • Water and Container Maintenance: To maintain freshness, change the water in the container every two days or whenever it appears cloudy. Rinse the container thoroughly each time to eliminate bacteria and debris. Regularly trim the stem ends by about 1/2 inch to remove any blocked vascular tissue and promote better water uptake.
  • Use of Flower Preservatives: Commercial floral preservatives, which typically contain sugar, acidifiers, and antimicrobial agents, can help prolong the life of picked Osteospermum. Alternatively, you can create a homemade solution by mixing 2 tablespoons of sugar, 2 tablespoons of white vinegar, and 1/2 teaspoon of household bleach in a quart of water. This solution nourishes the flowers, maintains a low pH for better nutrient absorption, and inhibits bacterial growth.


Cut stems at a 45-degree angle, remove submerged leaves, and choose the right time to cut. Change water regularly, maintain container cleanliness, and trim stem ends. Use commercial preservatives or a homemade solution to nourish flowers, maintain a low pH, and inhibit bacterial growth.

Average Lifespan of a Picked Osteospermum

  • Typical Lifespan: With proper care, a picked Osteospermum can generally last between 5 to 10 days. However, the specific lifespan depends on factors such as the maturity of the flowers when picked and the quality of care they receive.
  • Individual Experiences May Vary: Flower maturity and individual care practices can significantly affect the lifespan of a picked Osteospermum. For instance, blooms that are picked at the right stage of maturity, such as when the outer ring of petals is just beginning to open, tend to last longer. Additionally, diligently following the care tips outlined above can greatly extend the life of your Osteospermum blooms.


With proper care, picked Osteospermum can last 5-10 days. Lifespan varies based on flower maturity and individual care practices.
