Growing and Maintenance Tips

Gentians tend to grow best in cooler zones with mild summers. 'True Blue' can grow in the garden right along with your other perennials since it is not an alpine type. It prefers full sun to part shade and should be protected from the afternoon sun in regions with hot, humid summers. Plant it in well-drained, sandy loam with average moisture. If the soil stays wet, especially in winter, the plant may rot.
