Summary

Machaeranthera tanacetifolia, commonly known as Tanseyleaf Tansyaster or Tahoka Daisy, is an annual or biennial herb that is part of the Asteraceae family. It is native to prairies, plains, and roadsides in northern Mexico and the southwestern and central United States. This plant typically grows to a maximum height of about 70 cm (28 in) and features branching stems. The foliage is reminiscent of tansy with its finely divided leaves. The inflorescence is composed of flower heads with a center of yellow disc florets surrounded by a fringe of lavender to purple ray florets, each 1 to 2 cm (1⁄3 to 2⁄3 in) long, blooming from late summer to fall. The flowers are quite showy and attract a variety of pollinators.

Tanseyleaf Tansyaster is valued for its drought tolerance and vibrant floral display, making it a suitable choice for wildflower gardens, xeriscaping, and restoration projects. It thrives in full sun to part shade and prefers well-drained soils, although it can tolerate a range of soil types. This plant is relatively low-maintenance, requiring only moderate watering once established. It can self-seed prolifically under favorable conditions, which should be considered when planting in garden settings to prevent unwanted spread.CC BY-SA 4.0
