]. The following notes are based on the general needs of the genus.
Prefers a moderately fertile moisture-retentive well-drained soil, succeeding in full sun if the soil remains moist throughout the growing season, otherwise it is best in semi-shade[
]. Dislikes shade according to another report.

The roots are diuretic, expectorant, haemolytic and sedative[
]. Their use lowers the blood pressure[
