Begonia sizemoreae aka Cats Tongue
Taxonomy
Begonia sizemoreae, a species of flowering plant in the family Begoniaceae, is native to Laos and Vietnam. This popularly cultivated begonia produces a clump of rounded leaves, approximately 15cm across, that are dark green with a pale green band. The leaf surface is deeply crinkled and adorned with long, scattered white hairs, while the undersides and stems are dark red and densely hairy. In late summer and autumn, it produces beautiful flowers in two shades of pink.
Begonias, with over 2,000 species, have been further diversified by horticulturalists through cultivation, resulting in a wide array of shapes and colors. Originally native to tropical regions, these plants can now be found in homes even in colder climates. However, their taxonomy is more complex compared to other plants, as they belong to different cultivar groups. It's important to note that begonias contain oxalic acid, so extra caution should be taken to keep them out of reach in households with pets or children.
Common names
Cats Tongue, Tongue LeafHow to care for Cats Tongue
Water
Cats Tongue should be watered regularly, allowing the soil to dry out between waterings.
Soil
Cats Tongue loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Cats Tongue prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Dormancy
The Cats Tongue does not display a conventional dormancy pattern. If the growth rate slows significantly, verify that the plant is receiving adequate amounts of sunlight and water for healthy growth.
Toxicity
No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.
Humidity
The Cats Tongue does not demand additional humidity levels. Water is mostly absorbed by the roots of plants, rather than their leaves, and the best way to provide humidity to your plants is through watering the soil.
Fertilizer
Once the Cats Tongue has doubled in size or after a year has passed, it should be moved to a new pot. By replacing the soil with fresh potting soil containing all the vital nutrients, your plant will receive all the sustenance it needs, negating the requirement for fertilizer. It's important to remember that plants get their energy from the sun, not fertilizer.
Region of origin
Cats Tongue’s native range is Tropics and Subtropics worldwide.
