Growing Requirements Rudbeckia triloba:
To successfully grow Rudbeckia triloba and enjoy its charming blooms, it is important to provide the following growing conditions:
Sun Exposure: Rudbeckia triloba thrives in full sun. Choose a location that receives at least 6 to 8 hours of direct sunlight each day to ensure optimal growth and flowering.

In autumn, once the flowering season is complete, you can cut the plant back to ground level. This helps tidy the plant and promotes new growth in the following season.
