Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during dry periods. This plant thrives in wet conditions and can tolerate shallow standing water, making it suitable for bog gardens or pond edges.
Deadheading spent flowers can encourage more blooms and prevent self-seeding if unwanted. Minimal pruning is otherwise required. Remove any dead or damaged foliage as needed.
Easily grown from seed sown directly outdoors in spring after the last frost, or started indoors a few weeks prior. Seeds require light to germinate. Self-seeds readily in suitable conditions.
As an annual, repotting is not applicable for established plants. If starting seeds indoors, transplant seedlings into larger pots once they have developed a few true leaves.
