Kalimeris incisa, commonly known as Japanese Aster, is a deciduous perennial herb native to grasslands, meadows, and the edges of forests in East Asia, including China, Korea, and Japan. It typically grows to a height and width of 1-2 feet (0.3-0.6 meters), forming a mounded clump. The plant features daisy-like flowers with pale blue to violet petals surrounding a yellow center, blooming from mid-summer to fall. The flowers are moderately showy and attract pollinators such as bees and butterflies.

Japanese Aster is valued for its long flowering period and its ability to thrive in a range of garden settings. It is often used in borders, cottage gardens, and as a filler in mixed beds due to its compact size and floriferous nature. It is also relatively low maintenance, requiring minimal care once established. In cultivation, it prefers full sun to part shade and adapts to various soil types, provided they have good drainage. Regular watering is needed, especially in dry conditions. While generally disease-resistant, it can be prone to powdery mildew in humid climates. Deadheading spent flowers can encourage a longer blooming period and prevent self-seeding.CC BY-SA 4.0
