Additional Care Tips

Water regularly to keep the soil consistently moist, especially during the growing season. Reduce watering slightly in cooler months but do not allow the soil to dry out completely.

Generally does not require pruning. Remove any dead or damaged foliage as needed to maintain appearance. Can be cut back hard if it becomes overgrown or untidy.

Easily propagated by division of clumps in spring or by seed. Seedlings may require warm temperatures and consistent moisture to germinate successfully.

If grown in a pot, repot every 1-2 years in spring when the plant becomes root-bound. Use a well-draining potting mix. Ensure the new pot is only slightly larger than the previous one.
