Kalimeris integrifolia, commonly known as Double Japanese Aster or Michaelmas Daisy, is a deciduous perennial herb that is native to meadows, grasslands, and open forests of East Asia, particularly China and Korea. It exhibits a moderate growth rate, reaching a height of 1.5-2 feet (0.46-0.6 meters) and a width of 2-3 feet (0.6-0.9 meters). The plant forms a clump of upright stems with lance-shaped leaves, and during the summer and fall, it produces an abundance of daisy-like flowers with white or purple petals and yellow centers, which are quite showy and attract pollinators.

Kalimeris integrifolia is valued for its long blooming period and its ability to thrive in a variety of garden settings. It is often used in borders, cottage gardens, and as a filler in mixed beds due to its compact size and attractive flowers. This plant is relatively low maintenance, tolerating some drought once established, and is resistant to many pests and diseases. It prefers full sun but can tolerate part shade, and it grows best in medium or slow draining loam or sandy soils with regular moisture. While not invasive, it can self-seed in optimal conditions, which can be managed by deadheading spent flowers.CC BY-SA 4.0
