The 'myripnois ' genus, of Asteraceae family, is a group of perennial herbs requiring intermediate care. They thrive best in full to partial sunlight and well-draining, fertile soils. Regular watering, without waterlogging, helps these plants flourish. They prefer moderate temperatures, avoiding exposure to extreme cold. Common challenges gardeners face include attacks by aphids, powdery mildew, and root rot due to excessive water. Seasonal considerations include increased watering in summer and less in winter, along with monitoring pest infestation during wetter seasons.
