The delicate bellflower grows preferably in the garden or in a planter on the balcony. Campanula isophylla in particular, with its mostly blue, violet or white flowers, is also ideal as a houseplant.
How do you care for a bluebell as a houseplant?
The bellflower, especially Campanula isophylla, is suitable as a houseplant. It requires a bright location without direct sun, loose and nutrient-rich substrate, regular watering, fertilizing with liquid fertilizer for flowering plants and removing wilted flowers for continuous flowering.
Description
Campanula isophylla, the star bellflower, is an evergreen species of bellflower that is originally native to northern Italy. If the houseplant is grown upright, its shoots will be up to 20 centimeters long, but if placed hanging, the tendrils can become even longer. The star bellflower forms a rhizome from which it sprouts reliably every year. Their flowering period lasts from June / July to September.
The ideal location
Like almost all types of bellflowers, the star bellflower prefers a bright location, but without direct sunlight. In particular, the intense midday sun should be avoided, as this can cause burns to the sensitive leaves and flowers. Therefore, a location directly behind glass on a south-facing window is not very advisable, but windows facing west or east provide just the right amount of light. The plant can be wonderfully planted in a hanging basket, which can either be hung in the room or placed on the balcony or terrace.
Planting substrate
Bluebells like Campanula isophylla prefer a loose, nutritious and well-drained substrate, which should ideally have drainage on the bottom of the pot. Clay shards or expanded clay balls are suitable for this purpose and simply form the first layer below the potting soil. Normal, commercially available potting soil is completely sufficient as a substrate, which you can mix with sand and/or perlite.
Properly care for bellflowers in the room
Bluebells grown indoors need to be watered and fertilized regularly. The rule of thumb is that the warmer the plant is, the more you have to water. To fertilize, it is best to use a liquid fertilizer for flowering plants (€14.00 on Amazon). By regularly cutting off the faded bluebell flowers, you encourage the plant to bloom continuously throughout the growing season.
Tips & Tricks
Bluebells kept indoors can also be easily propagated by division once they have grown large enough.
