Tarenaya houtteana, commonly known as Pink Queen, Spider Flower, or Grandfather’s Whiskers, is an annual herb originally from South America. It is typically found in open areas such as roadsides and fields. This plant exhibits rapid growth, reaching heights of 3-4 feet (0.9-1.2 meters) and widths of 2-3 feet (0.6-0.9 meters). The Spider Flower is notable for its distinctive inflorescence with long, protruding stamens that resemble spider legs, hence the name. The flowers are pink and quite showy, blooming profusely in summer and fall, attracting pollinators such as bees and butterflies.

In cultivation, Tarenaya houtteana is valued for its ornamental flowers and is used in borders, cottage gardens, and as a specimen plant. It thrives in full sun and prefers well-drained soils, including clay, loam, or sandy types. Regular watering is necessary to keep the plant healthy, especially during dry periods. While it is relatively low-maintenance, it can self-seed and become weedy if not managed properly. Gardeners should be cautious as it is known to be potentially invasive outside its native range, and it is advisable to check local regulations before planting.CC BY-SA 4.0
