The ideal soil is a deep, fertile, well-drained loam but it will grow in most soils and has good drought tolerance. We advise against moving this plant as new shoots will emerge from deep roots unavoidably left behind and may be difficult to eradicate. Has the potential to become a nuisance if not managed well
