The best time to plant Illicium parviflorum, commonly known as yellow anise, is during the cooler months of early spring or fall. These periods provide the ideal conditions for root establishment before the intense heat of summer or the cold of winter sets in. Planting in early spring allows the shrub to take advantage of the growing season, promoting vigorous development and acclimatization. Alternatively, fall planting gives the roots time to settle and grow in mild temperatures, leading to robust growth in the following spring. Ensure the planting site has well-draining soil and partial to full shade, as Illicium parviflorum thrives in these conditions, providing lush, evergreen foliage and fragrant flowers to your landscape.
