Phacellanthus, a unique plant genus, demands moderate care. The Basic Care Needs include indirect light exposure, regular watering when the soil is dry, average room temperatures, and well-draining sandy soil. Common Challenges entail managing pests like aphids and spider mites, combating root rot, and protecting against frost. Seasonal Considerations involve reducing watering in winter to avoid waterlogging and keeping them in bright but indirect light throughout the year. Always refer to a trusted horticulture guide for the accurate care of each phacellanthus species.
