Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged, especially during the growing season. Reduce watering in fall and winter, allowing the soil to dry slightly between waterings to prevent root rot.
Ensure good drainage to avoid overly saturated conditions.
Deadhead spent flowers to encourage reblooming and maintain a tidy appearance. Cut back the foliage to the ground in late fall or early spring before new growth begins.
Remove any dead or damaged stems throughout the growing season as needed.
Propagate by division in early spring or fall. Carefully dig up the plant and divide the root ball into sections, ensuring each section has at least one bud. Replant divisions immediately in well-draining soil.
Can also be grown from fresh seed sown in fall.
Repot container-grown plants every 2-3 years in early spring or fall. Choose a pot that is slightly larger than the current one and use a well-draining potting mix.
This helps refresh the soil and provides more space for root growth.
