How to Grow Perennial Bell Flowers
- Bellflowers are considered one of the easiest perennials to grow. Although bell flowers require full sun, they can also grow in partial shade.
- Perennial bell flowers need to be watered once to twice a week. The soil should stay moist and well-drained. They also require fertilizer about once or twice every season. Use a 10-10-10 fertilizer, or one formulated for perennial flowers.
- Adding a thick layer of mulch is important to help keep soil moisture for young bellflower plants, however, once they are established, they don't require any mulching or protection during the winter season.
Bellflower: Frequently Asked Questions
Do bell flowers come back every year?
Bellflowers are perennials, and will come back every year. These plants sprout in spring, and will bloom in July or August in most temperate climates.
Do bell flowers like sun or shade?
One of the best things about bellflowers? Their versatility. Bellflowers can thrive in full sun or partial shade, and have been known to pop up even in shade gardens. As long as these plants get some indirect light, they'll come back. However, you'll see the best blooms when these perennials are planted in full sun.
Are bellflowers invasive?
Creeping bellflower, Campanula rapunculoides, is extremely invasive. Clustered bellflower, like the one available from Michigan Bulb, is a separate, but related plant. Clustered bellflowers certainly spread with gusto, but are not universally considered invasive. If you want to keep this plant contained, be sure to cut back your flowers each fall, and dig up any spreading rhizomes.
Do bell flowers spread?
Bell flowers are certainly spreaders! These plants are great for naturalizing, especially considering their low care needs.
Do bell flowers bloom all summer?
Bell flowers bloom later in the season, beginning in July or even August, but they won't quit blooming until the cooler temperatures of fall arrive. These are perennials designed to carry you through the summer season!
Do you cut back bellflower?
After blooming, your bellflowers can be cut back to the ground. Cutting them back prevents reseeding and tidies up the garden. These perennials will come right back next year.
Where should you plant bellflowers?
The bellflower is one of the easiest plants to grow, and it will quickly fill in any site you want it to. Their fast spread means that you'll have a full, lush-looking flower bed in no time. Small, heart-shaped leaves and dense clusters of violet-blue flowers look spectacular when planted in groups, whether in large containers, along fences, or aligned in your flower beds.
