Campanula flowers, also known as Bellflowers, have the ability to spread slowly over time. They do this through a combination of self-seeding and underground rhizomes. This means that once you plant Campanula in your garden, you may find that it starts to pop up in other areas as well.
One of the ways Campanula spreads is through self-seeding. This is when the flowers produce seeds that fall to the ground and germinate on their own. This can be a beautiful and natural way for the plant to reproduce and spread throughout your garden. However, if you prefer to control the spread of the Campanula, you can deadhead the flowers before they have a chance to produce seeds. Deadheading is the process of removing the spent flowers, which helps to encourage more blooms and prevents the plant from putting energy into seed production.
Another way Campanula spreads is through underground rhizomes. Rhizomes are horizontal, underground stems that can produce new shoots and roots. These rhizomes allow the plant to slowly spread outwards, creating new clumps of Campanula in different areas of your garden. If you want to control the spread of the plant, you can dig up the rhizomes and remove them. However, be careful when doing this, as the rhizomes can be quite delicate and can easily break.
In terms of growth rate, Campanula is generally considered a slow spreader. This means that it will take some time for the plant to expand and fill in an area. However, given the right conditions, such as ample sunlight, well-draining soil, and regular watering, Campanula can gradually increase its presence in your garden.
It’s worth noting that not all Campanula varieties spread in the same way. Some varieties, like Campanula ‘Samantha’, have a slower spreading habit and are less likely to take over your garden. These types of Campanula are great for rock gardens, edging, growing in containers, or as a groundcover. They can add a pop of color and interest to your landscape without becoming invasive.
In my personal experience, I have planted Campanula in my garden and have seen it slowly spread over the years. I find it to be a delightful plant that adds charm and beauty to my landscape. I enjoy watching as new clumps of Campanula emerge in different areas of my garden, creating a lovely tapestry of color.
Campanula flowers do have the potential to spread, but their growth rate is generally slow and can be controlled with proper deadheading and rhizome management. With their stunning blooms and versatile uses, Campanula is a fantastic addition to any garden.
