| Bailey's Notes |
Trollius are ideal for damp garden spaces, including pond edges and bog gardens, where their vibrant blooms thrive in consistently moist soil. These perennials may take a couple of years to establish fully but are well worth the wait. Both Trollius chinensis 'Golden Queen,' with its golden-orange, bowl-shaped flowers, and Trollius × cultorum 'New Moon,' showcasing delicate pale-yellow blooms, add style to garden beds, borders, cottage gardens, and rain gardens and have a long vase life to boot. Deadheading spent blooms encourages continuous flowering, while cutting back stems after the first flush can prompt a second wave of blossoms. Dividing clumps in early spring or right after flowering helps maintain plant vigor. To ensure healthy growth, keep the soil consistently moist, enrich it with organic matter, and monitor for powdery mildew in humid conditions. If you have wild buttercups growing naturally in your plot or adjacent area, these cultivars will likely thrive. |
