The Calathea warscewiczii, often called the Jungle Velvet Calathea, is a striking tropical plant cherished for its lush, velvety foliage. While many admire its distinctive leaves, it can also produce a unique and beautiful flower, adding another layer of appreciation.
The Unique Calathea Warscewiczii Flower
The blooms are typically creamy white or yellow, forming a distinct cone-shaped inflorescence. These cone-like structures are composed of numerous bracts, modified leaves that initially emerge creamy white and can gradually shift to a light yellow or even acquire a pinkish tint as they mature.
The bracts are spirally arranged, with their rims folding over the edges, creating a form some describe as resembling a rose flower when viewed from above. This texture and shape distinguish it from many other houseplant blooms. The actual flowers are small and often peek out from between these showy bracts.
Care for Optimal Flowering
To encourage Calathea warscewiczii to bloom, provide environmental conditions that mimic its native tropical rainforest habitat. Consistent and appropriate care supports the energy production necessary for flower development.
Bright, indirect light is necessary for this plant’s health and its ability to flower. Direct sunlight can scorch its velvety leaves and inhibit flowering, as it is accustomed to filtered light from the rainforest understory. An east-facing window or a spot several feet from a south or west-facing window, protected by sheer curtains, offers ideal light conditions.
High humidity levels are also necessary for the Calathea warscewiczii to thrive and produce blooms. Aim for humidity above 60%, as low humidity can lead to stress, indicated by brown leaf tips, which can deter flowering. Utilizing a humidifier, placing the plant on a pebble tray with water, or grouping it with other plants can help maintain the necessary moisture in the air.
Proper watering techniques prevent plant stress and promote flowering. The soil should remain consistently moist but never waterlogged, as this can lead to root rot. Allowing the top inch or two of soil to dry slightly before rewatering is a good practice. Using distilled, filtered, or rainwater is often recommended, as these plants can be sensitive to chemicals like chlorine and fluoride found in tap water.
A well-draining, peat-based potting mix that retains moisture is suitable for Calathea warscewiczii. Incorporating perlite or vermiculite can enhance drainage while still providing the moisture retention these plants prefer. This balance ensures roots have access to water without becoming waterlogged, supporting overall plant vigor and bloom potential.
Regular fertilization during the growing season supports the plant’s energy needs for foliage and flower production. Fertilize every four weeks during spring and summer with a diluted, balanced liquid houseplant fertilizer. Reducing fertilization in fall and winter is advised, as the plant’s growth slows during these cooler months.
Maintaining a stable temperature range also encourages blooms. Calathea warscewiczii prefers temperatures between 65°F and 80°F (18°C to 27°C). Avoiding sudden temperature drops and cold drafts prevents stress that can negatively impact flowering.
Flowering Cycle and Longevity
Calathea warscewiczii typically flowers during its active growing season, generally from late winter to early spring, and can extend into summer months. While many Calatheas are grown primarily for their foliage and rarely bloom indoors, the warscewiczii variety is known for its ability to produce flowers under suitable conditions.
Individual blooms can last for several weeks, contributing to an extended period of interest. The overall flowering period can vary, but a mature plant, when provided with optimal care, may bloom repeatedly. Flowering can be an infrequent event for indoor Calathea warscewiczii, and some plants may take time to mature sufficiently before producing their first bloom.
Post-Flowering and Troubleshooting
Once the Calathea warscewiczii flower fades, deadhead the spent blooms by trimming away the faded flower stalks at their base. Removing these old blooms allows the plant to redirect its energy towards new foliage growth, rather than expending resources on developing seeds.
If a Calathea warscewiczii is not flowering, several factors could contribute to the issue. Insufficient light is a common reason, as the plant needs adequate indirect light to produce the energy required for blooming. Low humidity levels can also inhibit flower development, as these plants thrive in high moisture environments. Inconsistent watering, either too much or too little, causes stress that can prevent blooming. A lack of maturity can also be a factor, as younger plants may not yet have the stored energy to produce flowers.
