How to Care for a Trollius Plant!

Genus Trollius

Though gardeners might think that finding plants that are tolerant to dry areas or areas with very poor soil, it’s actually so much harder to find plants that are tolerant to very wet areas and areas with really packed and wet soil!

Fear not gardeners with very damp gardens, let me introduce you to the trollius plant. Trollius plants are members of the ranunculus family, making them part of the buttercup family! Trollius plants are not commonly found growing in gardens because they have a reputation for being high maintenance, but this is not at all the case as long as they’re planted in the right spot on your property.

The trollius genus has 30 different flowering plant species that are more commonly known as the globe flower. Members are the absolute perfect specimen for a bog garden, to plant near a stream or pond (since they love moist conditions) and are often used as a mass bedding plant because of their display of extremely bright blossoms. Not to mention they also make amazing cut flowers.

What do Trollius Plants Look Like?

Growth Habit

Starting underneath the surface, globe flower plants grow from very wide spreading and fibrous roots. These are very sturdy roots that help the plant survive through the sometimes harsher climates of North America.

From here will grow long and erect flowering stems and leaf stems that can grow to be anywhere from 18 inches to 3 feet in height. Refined foliage stays closer to the ground while flowers rise above the low growing leaves.

Trollius’ are a perennial plant type, meaning that they will continue to bear flowers year after year as long as their ideal growing conditions are met and maintained.

Leaves

Trollius foliage is very complimentary to the rest of the plant. It hovers closer to the ground in a mounding habit and each individual leaf is very finely textured and deeply lobed.

These dark green trollius leaves are deciduous, meaning that they will eventually change color and fall away as the cold weather approaches.

Flowers

Now for the show stopper: trollius flowers. Gardeners love globeflowers because they have a very attractive rounded shape and a single flower will rise from a single stem. When planted in mass, they create quite a display.

Trollius flowers will often bloom in the late spring or early summer and will last into the late summer and sometimes even late fall if you’re lucky! Flowers are comprised of several flower petals that curve upwards creating that iconic ball shape. Flowers will be either bright yellow, bright orange, and sometimes a light purple flower color.

Trollius flowers are also known for attracting pollinators and other beneficial insects to the area thanks to their very sweet smelling nectar. These blossoms are super important to bee populations!

What are some Notable Trollius Species?

Trollius x Cultorum

‘Lemon Queen’ is a superbly popular trollius cultivar thanks to its masses of rounded blossoms that bloom from the late spring to early summer. These yellow flowers are accompanied by finely texture foliage and very upright flower stems.

‘Orange Princess’ is another very popular cultivar. This upright herbaceous perennial plant has bowl shaped orange flowers that are said to look very similar to double buttercups. They are known for having dark green leaves.

Trollius Europaeus

Trollius Europaeus is an upright herbaceous perennial plant that produces incredibly bright yellow flowers. They are born on tall and erect flower stalks, high above those characteristically fine textured dark green leaves.

Trollius Laxus

Trollius laxus is a rather rare variety of trollius. It is more commonly known as the American globe flower and is considered as being an endangered species in North America.

Unfortunately these beautiful herbaceous perennials can only be found growing in small ranges of remote wetlands and fens. They can be identified by their deep yellow flowers and dark green leaves.

Trollius Chinensis

Trollius chinensis is a gorgeous plant that is known for having very elegant blossoms. These perennials bear bright orange flowers that rise above deeply toothed leaves. ‘Trollius golden queen globeflower’ is a very popular cultivar thanks to those gorgeous orange blossoms.

Where is Trollius a Native Plant?

Good gardeners known that a decent amount of research is required before adding a new specimen to their spring planting list. One of the most important things to know is where a plant is considered as being a native species.

This is because there are certain plants that simply can’t survive in certain biomes. Learning about the natural growing conditions of a plant will better enable you to mimic those conditions and keep a plant happy in other parts of the world.

Luckily, when it comes to trollius plants, they can survive in any temperate region in the northern hemisphere. When growing wild they can be found growing in super moist areas, near ponds, rivers, and streams, or in very damp woodlands.

Trollius plants can live happily outdoors all year long in USDA growing zones 3 through 7, but should be brought indoors for the cold winter months outside of those zones. In this situation, plant trollius in a container!

What are the Ideal Growing Conditions of Trollius Plants?

Now it’s time to convince you that caring for trollius plant isn’t really as hard as their reputation says! Caring for a trollius plant is pretty straight forward and their maintenance can easily be incorporated into your regular gardening routine. Just follow these simple tips:

Soil Type

Something rather unusual about trollius plants is their ability to grow in clay soils. This really is not common when it comes to garden plants, so it’s a great specimen to know about if you happen to live on a property with packed soil.

They also seem to perform quite well in rocky soil as long as it remains moist. Moist soil that is fertile is also ideal, but this can be achieved by incorporating compost into the soil at the beginning of the growing season.

Water Level

The thing that will take the most time out of your day is maintaining the moisture level of your trollius’ soil. These plants really love moisture and will perform their absolute best if soil is kept moist throughout the year.

This is indicated by where they tend to grow in the wild, which is always in damp forests or open meadows, or very close to various waterways like a pond, stream, or river.

Sun Exposure

Trollius plants aren’t too picky when it comes to the amount of sun exposure that they receive. They love living in direct sunlight for the majority of the day, but they can also handle living in partial shade conditions.

Temperature

As long as you in a temperate region, your trollius plant will be completely fine. What they don’t appreciate is being exposed to extreme summer heat and extreme winter cold.

Trollius plants survive happily outdoors all year long in USDA growing zones 3 through 7, but should be brought indoors for the colder months outside of those growing zones.

Fertilizer

Something that trollius plants love is living in fertile soil. You can provided fertilizer for your plants in the early spring right before their growing season starts, or you can incorporate some compost into the mix for a similar outcome.

Pruning

Pruning is not necessary for the health of your trollius plant. You can decide to cut back the flowering stems after the plant has finished blooming and this will sometimes encourage another blooming period!

How do you Propagate a Trollius Plant?

Now for the final step of your trollius learning journey is how to propagate a specimen of your very own. This is best done through taking cuttings or by transplanting a young plant. This is because trollius seed can take up to 2 years before successful germination occurs. Follow these simple steps:

1. Wait until the last frost of the winter (late winter or early spring, depending on where you live) has passed before deciding to transplant your young trollius plants.

2. Pick a spot on your property that receives either full sun or partial shade and in moist soil that is relatively fertile.

3. Dig holes for individual plants that are between 18 and 22 inches apart from one another, depending on the look that you want to achieve. Trollius plants are really great for mass ground cover planting.

4. Make sure to water deeply as the plants are getting established and all throughout their growing season. Moisture is the key to a happy trollius plant!
