Globeflower Trollius europaeus

Water

The Globe Flower should be watered regularly to keep the soil consistently moist but not waterlogged. Typically, watering once a week with about 1 to 1.5 gallons of water should suffice. However, during the hotter, drier months, you may need to water more frequently, especially if the plant is in full sun and the soil is drying out faster. Conversely, reduce watering during cooler, wetter periods to prevent root rot. Always check the soil moisture level before watering to gauge if additional water is needed.

Light

Globe Flowers prefer a location with full sun to partial shade. Place them in a spot where they can receive at least 6 hours of sunlight a day for optimal growth and flowering. They can tolerate some light afternoon shade, which can be beneficial in hotter climates to prevent scorching of the leaves.

Temperature

Globe Flowers thrive in a range of temperatures, typically between 60°F and 75°F, which are ideal for their growth. They can survive minimum temperatures down to about 0°F and can tolerate up to the high 80s°F, but prolonged exposure to temperatures outside this range can be detrimental to the plant's health.

Pruning

Prune Globe Flowers to remove spent flower heads and encourage a second bloom. Additionally, cutting back the foliage after the first frost in the fall helps maintain plant health. The best time for a more thorough pruning is in early spring before new growth begins.

Cleaning

As needed

Soil

Globe Flower thrives in a soil mix that is moist, well-draining and rich in organic matter, with an ideal pH of 6.0 to 7.5. A mixture of loam, peat, and some sand is beneficial for proper drainage and fertility. Regular addition of compost or well-rotted manure can enhance the soil conditions.

Repotting

Globe Flower typically does not require frequent repotting as it grows well in the same spot for several years. However, it can be repotted every 3 to 4 years to replenish the soil and divide the clumps if necessary.

Humidity & Misting

Globe Flower prefers high humidity levels but is tolerant of a range of conditions. It naturally grows in moist environments, so replicating a humid atmosphere will support healthier growth.

Suitable locations

• Indoor

  Place in partial shade, keep soil moist.

• Outdoor

  Part sun, moist soil, shelter from strong wind.

• Hardiness zone

  3-7 USDA

Life cycle

Globe flower (Trollius europaeus) begins its life cycle as a seed, which upon favorable conditions germinates in the soil, typically in spring, to develop a small root system and shoot. The shoot grows into a rosette of leaves at the ground level, absorbing sunlight and nutrients to fuel further growth. After establishing a firm root system and foliage, it advances to the flowering stage, usually in late spring or early summer, producing distinctive, bright yellow, globe-shaped flowers that are attractive to various pollinators. Following pollination, the flowers develop into fruit, which are capsule-like structures containing several seeds. When the fruits mature, they release seeds back into the environment to continue the propagation cycle. The plant is a perennial, thus after the flowering and seeding stages, it may die back to the ground in colder climates during winter, before regrowing from the same root system in the following spring.

  Spring to Summer

• Trollius europaeus, commonly known as the globe flower, is propagated predominantly through seed sowing or by division. For seed propagation, it's best to sow the seeds as soon as they are ripe in the late summer to fall. However, for many gardeners, division of this perennial in early spring or in the fall after flowering is the favored method. It involves carefully lifting the parent plant from the ground using a spade or fork, ensuring as much of the root system as possible is kept intact. The clump should then be divided into smaller sections, each with at least one growing point. These sections can then be replanted in the ground at the same depth they were previously growing, spaced about 12 to 24 inches (approximately 30 to 60 centimeters) apart to allow enough room for growth. Adequate water should be provided to help the new divisions establish.
