Need some colour after a long winter? Fortunately, the first Campanulas start peeping out from March onwards. With their bell-shaped flowers and fresh green stems, they brighten up any outdoor space. Blue, pink, lavender-purple, white … intense, soft, romantic. The Campanula has many faces. The result of passion and craftsmanship. This article introduces you to our main growers, both in the Netherlands and in Denmark.
Bright spot after winter
It gets its name from the shape of its flowers: Campanula is Latin for ‘bell’. It originates from northern Italy, where it forms a colourful hanging carpet over rock formations. Forming such an impressive carpet hardly takes any effort, as Campanula is a fast grower. And a tenacious one. With the right care, it flowers three to four times a year, each time for four to six weeks.
Especially if you follow the following maintenance tips:
- Place the plant in semi-shade.
- Give a splash of water up to twice a week.
- Remove spent flowers to encourage new blooms.
- Let the plant overwinter and enjoy its flowers again the following season.

Two iconic varieties
Campanula Addenda® offers two special types: Ambella® and Adansa®, each with its own character.
Campanula Ambella® (Campanula portenschlagiana)
The Campanula Ambella® is a classic. It stands out for its bulbous and compact flowering with bell-shaped flowers in four beautiful colours: Intense Purple, Lavender, White and Pink. Campanula Ambella® shines even more in a large patio pot or in a bowl on the table.
The Ambella® is grown in 10.5 cm, 12 cm, 14/15 cm, hanging pot and campana pot.
Campanula Adansa® (Campanula poscharskyana)
The Adansa® is a descending grower with spreading tendrils and star-shaped flowers. It is available in three colours: purple, white and pink. Characteristic is the white centre in the core of the flower. Its creeping character makes Adansa® a perfect ground cover that does well in borders. Also in a hanging pot, Adansa® shines like a real ‘star’.
The Adansa® is grown in 12 cm, 14/15 cm.

Thoruplund Nursery: fresh breeze with Campanula Ocean®
Gartneriet Thoruplund, a Danish pioneer in the development of unique plants in 10.5 cm pots, was founded in 1946. Since 1974, Campanula has been one of their core crops. Their own Campanula varieties, sold under the name Ocean®, are known for their long shelf life, compact growth and winter hardiness. And their colours also stand out. How do they achieve this? By concentrating on certain characteristics. For instance, they carefully distinguish female and male plants. Breeding is done as a crossing. The process, from pollination to the production of the first 100,000 plants, takes three to four years.
A new dimension for Campanula Ocean®
Meet the latest generation of Campanula Ocean®: White Ocean®, Blue Ocean® and Pacific Blue Ocean®. These innovations stand for sustainable production and environmentally friendly materials. As a Portenschlagiana type, Campanula Ocean® is extremely suitable for the patio and in the open ground. In short, its compact growth, rich bud formation, long shelf life and winter hardiness make these plants a perfect choice.
In addition, the Campanula Double Midnight Ocean® shines in blue and white, with larger double flowers reminiscent of roses. In 2025, these are available from weeks 12-26.
