Care tips
It thrives in full sun to light partial shade and deep, rich, well-draining soil. Keep the soil consistently moist, particularly during dry spells, but avoid waterlogging which can lead to root rot. A common mistake is not providing enough space, as this plant requires ample room to grow to its full potential.
