The String of Tears plant (Senecio herreianus or Curio herreanus) is a distinctive succulent cherished for its unique appearance. Its plump, tear-drop shaped foliage cascades gracefully, creating a visually appealing display in hanging baskets or on shelves. Each leaf often features a translucent “window” that allows light to penetrate, aiding photosynthesis. While its charming foliage is a primary draw, this resilient plant also produces delicate flowers, adding another layer of appeal that many enthusiasts seek to cultivate.
The Unique Flowers of String of Tears
String of Tears plants produce small, delightful blooms. The flowers are white or pale yellow, resembling tiny daisies. These blossoms emerge on thin, wiry stalks up to 6 inches tall, adding subtle beauty above the trailing foliage. These flowers have a sweet, spicy fragrance, often compared to cinnamon or cloves, which can fill a room. They commonly appear from late summer to early winter, or sometimes from late winter into early spring.
Promoting Blooms: Essential Care for Flowering
Encouraging String of Tears to flower depends on specific environmental conditions. Bright, indirect light is important for bloom production, making an east or west-facing window an ideal indoor location. Insufficient light leads to leggy growth and hinders flower development. While the plant tolerates some direct sunlight, prolonged exposure to intense afternoon sun can scorch foliage, so filtered light is best.
Triggering blooms involves a slightly drier resting period, particularly during cooler months. This mimics the natural dormancy conditions the plant experiences in its native habitat. It is important to let the soil dry out completely between waterings, reducing the frequency during fall and winter. This controlled drought stress signals to the plant to shift energy towards flowering rather than vegetative growth.
Fertilization also plays a supportive role in encouraging robust blooms. During the active growing season (spring and summer), apply a balanced, low-nitrogen liquid fertilizer. This should be diluted to half or even quarter strength and provided monthly or every 4-6 weeks. Avoid fertilizing during the plant’s dormant period (fall and winter), as this can disrupt its natural cycle and lead to soft, unhealthy growth rather than flower development.
Maintaining a Healthy String of Tears
Maintaining String of Tears health provides a strong foundation for flowering. The plant requires a well-draining succulent or cactus potting mix to prevent waterlogging and root rot. This mix often includes perlite or pumice to enhance drainage. Choose a container with drainage holes, and consider terracotta or unglazed ceramic pots, which wick away excess moisture.
String of Tears thrives in moderate temperatures (60°F-85°F / 18°C-29°C) and is not tolerant of frost. Average household humidity levels are sufficient, as these plants prefer low to moderate humidity. Good air circulation is also beneficial to prevent moisture buildup around the foliage.
While low-maintenance, String of Tears can encounter pests like mealybugs and spider mites, especially if overwatered or stressed. Consistent good care, particularly proper watering, is the best preventative measure. If pests appear, they can be managed with insecticidal soap or neem oil.
