Solidago ×calcicola, commonly known as Hybrid Goldenrod or Limestone Goldenrod, is a hybrid perennial herb that is a result of crossbreeding between different Solidago species. It is native to calcareous grasslands and open areas in North America, where it thrives in alkaline soils. This plant typically grows at a moderate rate to a height of 2-3 feet (0.6-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). It features erect, unbranched stems with narrow, lance-shaped leaves. The yellow flowers are small but numerous, arranged in dense, elongated clusters that bloom in the summer and fall, providing a showy display that attracts pollinators such as bees and butterflies.

Hybrid Goldenrod is valued for its adaptability to various soil types, including clay, loam, and sandy soils, as long as they offer medium to fast drainage. It is drought-tolerant once established, making it a low-maintenance choice for gardeners. This plant is often used in wildflower gardens, borders, and naturalized areas. It is also beneficial for erosion control due to its fibrous root system. While it prefers full sun, it can tolerate part shade, making it versatile in landscape design. However, gardeners should be aware that some goldenrod species can be aggressive spreaders, and while Solidago ×calcicola is generally not invasive, it should be monitored to prevent unwanted spread.CC BY-SA 4.0
