Summary

Hibiscus trionum, commonly known as Flower Of An Hour, is an annual herb native to the Mediterranean region and prefers open, sunny environments such as grasslands and fields. It typically grows to a height of 20–50 centimeters (8–20 inches), but can sometimes exceed 80 cm (30 inches). The plant features distinctive flowers that are usually white or pale yellow with a dark purple or maroon center, blooming in the summer and fall. The flowers are short-lived, often lasting only an hour, hence the common name. The foliage is light green and deeply lobed, adding to its ornamental value.

Flower Of An Hour is appreciated for its unique, showy flowers and its ability to grow in a variety of soil conditions, although it prefers well-drained soils. It is often used in annual borders, wildflower meadows, and as a filler in mixed beds due to its ease of maintenance and rapid growth. In cultivation, it requires full sun and moderate watering. While it is not particularly prone to diseases, it can become weedy due to its prolific self-seeding, which also contributes to its potential invasiveness when grown outside its native range. Gardeners should be cautious and check local regulations before planting to prevent unwanted spread.CC BY-SA 4.0
