Trollius is closely related to Ranunculus. Trollius usually grow in heavy, wet clay soils.

They have bright golden-yellow flowers. They are used as food plants by the larvae of some Lepidoptera species of butterflies and moths.

Some species are popular ornamental flowers in horticulture, with several cultivars selected for large and brightly coloured flowers, and have gained the Royal Horticultural Society's Award of Garden Merit.

Note: Ornamental use only. These seeds and/or plants are poisonous.

Seeds per pack: 15

Availability: If these seeds are showing out of stock, we strongly recommend joining our wait list, as these seeds have a very shorty viability window, and this helps ensure you get the freshest seeds possible! If they are available, they will only be available for a short time.

Germination: Sow the seeds just under the surface and water in. Leave them at room temperature for 4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination is generally 30-60 days after the warming period, though some can take longer.
