Are you looking for an easy-to-grow and diverse flower to plant this year? Campanula flowers (bellflowers) are beginner-friendly and produce adorable bell-shaped flowers that come in several colors. In this article, horticulture expert Matt Dursum covers how to plant, grow,....

and care for these eye-catching bloomers.

Campanula flowers, also known as bellflowers, are gorgeous spring and summer bloomers. They put on majestic little tubular to bell-shaped flowers that bloom in striking hues of blues, purples, pinks, whites, and violets.

Bellflowers grow low to the ground or tall and upright. Some species have a beautiful trailing growing habit, while others form big clumps of flowers. They’ll quickly form beautiful patches of color in flower beds, cut beds, or garden barriers.

These stunning bloomers are easy to plant and care for, making them perfect for beginner flower gardeners. Let’s dive into how to plant, grow, and care for these compact and colorful plants.
What Is Campanula (Bellflower)?
There are over 300 species of Campanulas to choose from, each one with its own growing habit, color profile, and shape. Depending on your climate zone, you can find annual, perennial, and biennial varieties to plant.

Today, these flowers are some of the most widely planted ornamental plants in the US. They thrive in a variety of climates and soil types. They spread quickly and form large clusters or areas of creeping foliage.

Some species are considered invasive because of their easy-growing and fast-propagating nature. Others, such as the fairy bellflower (Campanula persicifolia), are easier to control because of their upright nature.

One of the best traits of Campanula flowers is their ability to attract beneficial pollinators. Once these tiny flowers bloom, hummingbirds, bees, and other insects will swarm around them.

Characteristics
Bellflowers come in a huge variety of shapes, sizes, and colors. Some species grow upright while others form a trailing or clumping structure.

The flowers usually have a bell or tubular shape. Some species appear to have star-shaped blooms. They come in many colors, including violet, white, blue, purple, and pink.

The foliage is light to dark green and beautiful. Some species stay low-lying and barely reach 6 inches tall. Others can reach heights of over 3 feet in the right growing conditions.

Many species, such as the creeping bellflower (Campanula rapunculoides), are invasive in many parts of the US. Because of this, it’s best to stick to non-invasive campanula species, such as the American bellflower and the Dalmatian bellflower.

Native Area
Bellflowers are native to Europe, Asia, and North America, where they grow in meadows, forest margins, and forests. They adapted to multiple habitats and climates, producing over 300 species.

Some species are edible and were consumed regularly in medicinal teas and as foraged food. These edible flowers also became choice ornamentals in many regions of Europe and Asia because of their easy-growing nature.

In the 18th and 19th centuries, European gardeners brought them to North America. The plants quickly naturalized in many parts of the US. Today, several species are seen as invasive and grow wild.

Planting
Bellflowers are easy to grow from seed. Plant them as colorful ground covers or in garden borders. Many gardeners plant them along rock walls or hillsides for a dramatic effect.

I enjoy planting taller annual varieties along the borders of my cut gardens. They frame taller flowers nicely and contrast with deeper and darker colored flowers.

Be aware that some perennial varieties grow quickly and can become invasive in some locations. Because of their vigorous growing habits, it’s best to stick to annuals unless you’re ready for consistent pruning and upkeep.

Some trailing varieties grow well in hanging planters. You can hang these containers on porches and decks that get direct sunlight.
