Dieffenbachia plants are a popular choice for indoor greenery. These plants feature large, often variegated leaves displaying shades of green accented with white, yellow, or gold, making them an attractive indoor addition. Their adaptability and relatively straightforward care requirements contribute to their widespread appeal among houseplant enthusiasts.
The Dieffenbachia Bloom
Dieffenbachia plants are primarily grown for their ornamental leaves, yet they are capable of producing flowers. While blooms are common in their native tropical environments, their appearance on indoor plants is less frequent. When a dieffenbachia does flower, the bloom typically resembles the inflorescence of other plants in the Araceae family, such as peace lilies or calla lilies.
The flower consists of a pale green spathe, a modified leaf that encloses a central spadix. This spadix is a fleshy spike covered with many small, inconspicuous flowers. Indoor blooming usually indicates a mature plant receiving optimal care, including consistent bright, indirect light, stable temperatures between 65°F and 75°F, and appropriate humidity levels.
Consistent watering, allowing the soil to dry slightly between applications, and regular fertilization during the active growing season also contribute to the plant’s vigor. Despite these conditions, indoor flowering remains rare, as the plant prioritizes energy toward its foliage.
Managing Dieffenbachia Flowers
When a dieffenbachia flowers indoors, it draws significant energy from the plant. This energy expenditure redirects resources away from the plant’s attractive leaves, its primary ornamental feature. Therefore, many growers choose to remove the bloom to encourage continued robust foliage growth.
Removing the flower, known as deadheading, helps the plant conserve energy. To do this, use a clean, sharp cutting tool to snip the flower stalk near its base. This removal redirects the plant’s energy into producing new leaves and maintaining its overall health.
Maintaining good plant health through proper light, watering, and feeding supports its vigor, whether it flowers or not. While blooming can signify a well-cared-for specimen, the vibrant, patterned leaves are typically the main reason for cultivating dieffenbachia. Focusing on conditions that support lush foliage yields the most aesthetically pleasing results.
Important Safety Information
Dieffenbachia plants contain calcium oxalate crystals, which are microscopic, needle-shaped structures found throughout all parts of the plant. These crystals are present in the sap, leaves, stems, and any fruit that may develop. Contact with these crystals can cause significant irritation.
Ingestion of any part of the plant causes immediate, intense stinging and burning sensations in the mouth and throat. This irritation results in swelling, pain, and a temporary inability to speak, earning the plant its common name, “dumb cane.” Skin contact with the sap also causes irritation, redness, and itching; eye contact may lead to pain and swelling.
Due to its inherent toxicity, handle dieffenbachia plants with care. Wearing gloves when pruning or repotting can help prevent skin irritation. Additionally, keep dieffenbachia plants out of reach of children and pets to avoid accidental ingestion or contact.
