A sunny plant, native to North-Eastern America. In the first year, it forms a leaf rosette, which in the second year blooms with bright yellow flowers with an almost black center.

Sowing method: Year-round in a seed tray, first give 2-4 weeks of warmth (18-22° C), then a cold period in, for example, the refrigerator (+4° C) for 4-6 weeks, then slowly warm up to room temperature, after which germination will follow. The seeds germinate irregularly over a longer germination period. Therefore, do not discard the seedlings too quickly. Sowing in the open ground is also possible; in that case, simply let them overwinter, and germination will occur in spring.
