The name Microstigma comes from the Greek words “micro” meaning small and “stigma” referring to the female reproductive part of a flower. This genus is characterized by its small flowers, which are typically less than 1 cm in diameter, and its unique pollination mechanism.

Appearance
Microstigma plants are small, usually growing up to 1 meter in height. They have slender stems with small, toothed leaves that are arranged oppositely along the stem. The flowers are small, trumpet-shaped, and come in various colors including white, purple, pink, and red. The unique feature of Microstigma flowers is their pollination mechanism, which involves the female reproductive part (stigma) being split into two small lobes.
Care Guide
To care for Microstigma plants, it is important to provide them with well-draining soil and consistent moisture. They prefer bright, indirect sunlight and can be grown in hardiness zones 10-12. Fertilize with a balanced fertilizer every 2-3 months during the growing season. It is important to avoid over-fertilization, which can lead to leaf burn. Prune as needed to maintain shape and remove any dead or damaged growth.
Common Pests & Diseases
Microstigma plants are susceptible to spider mites, mealybugs, and whiteflies. Regularly inspect the plants for signs of infestation and treat with an appropriate insecticide if necessary. They are also prone to root rot if overwatered, so it is important to ensure proper drainage.
Habitat
Microstigma plants are native to tropical regions of Africa, Asia, and Australia. They typically grow in moist, shaded areas such as forest understories and along stream banks.
