Description
The European globeflower (*Trollius europaeus*) is a native perennial of wet meadows and stream banks that opens its bright yellow, globe‑shaped flowers from May to June. It grows aggressively and thrives in wet, nutrient‑rich soils such as those found at pond edges or in bog beds. The plant is mildly toxic throughout, especially to children and pets, so caution is advised when handling the sap. In many regions it is protected, so it should only be obtained from nurseries and never wild‑harvested. Its spherical blooms add a charming, slightly whimsical accent to damp perennial beds.
Care instructions
Plant in a semi‑shady to sunny spot with consistently moist, humus‑rich soil; it tolerates waterlogging well. Water regularly during dry spells, especially in the first year, as the plant dislikes drying out. After early summer flowering, cut back spent stems to the ground to encourage compact growth next year. Every three to four years, divide the clump in autumn to keep the plant vigorous and rejuvenate the stock. A light mulch of leaf litter or compost helps retain summer moisture and protects roots in winter.
