Bellflowers are a diverse, easy-to-grow group of plants that come in many sizes and varieties, perfect for a\u00a0low-maintenance cottage garden<\/a>. From diminutive alpine species to upright woodland varieties that make pretty cut flowers, most types of bellflowers feature the trademark bell-shaped blossoms, comprised of five petals fused at the base. Depending on the variety, these bells sometimes face upward on little mats of foliage, or they may dangle in the breeze, suspended in drooping clusters. No matter how they’re held, the display of blooms will always be abundant.<\/p>

\u00a0<\/div>

Bellflowers are\u00a0among the most popular blue flowers<\/a>, a rare hue in the plant world. While blue is the most common color, you can also find them in purple, white, and pink. These cheery little bells will grace your garden for weeks, generally starting in late spring and continuing through summer.<\/p>

Where to Plant Bellflower<\/span><\/h2>

Because this is such a diverse group of plants, it’s always best to research and read labels on specific varieties before\u00a0planting them in your garden<\/a>. Bellflowers are native to so many different geographic areas that what works for one type may not be ideal for another. With that in mind, there are some general tips for meeting bellflower care needs.<\/p>

\u00a0<\/div>

When looking for a place to plant your bellflowers, know that most species\u00a0prefer well-drained soil<\/a>. A few exceptions can handle moist soils and, in some cases, persistent wetness. However, many smaller alpine species prefer the opposite and like to grow in sharply drained soil. These types may even grow in rock walls, trough gardens, and other less-than-ideal places.<\/p>

\u00a0<\/div>

Most bellflowers will\u00a0perform best in full sun<\/a>. A few woodland species grow well in part shade and full shade, but for the best flower display, you should generally grow bellflowers in full sun. Sunshine also helps prevent taller varieties from flopping and needing stakes.<\/p>

\u00a0<\/div>

Invasive Plant<\/h3>

Many of the campanula species spread not only by seed but also by underground rhizomes. These plants can be extremely vigorous growers, potentially becoming invasive. Some species are already classified as such, and you should take caution before planting them. Check with local agencies, and research specific varieties if you have concerns. Eliminating these plants can be challenging once they’re established.<\/p><\/div><\/div><\/span>

How and When to Plant Bellflowers<\/span><\/h2>

Plan to plant your bellflowers in the spring, once you’re confident the\u00a0last frost has occurred<\/a>. Some varieties can also be planted in the fall. Choose an overcast day or wait until the late afternoon when the sun is less intense to prevent transplant shock. Prepare the soil by turning it under, roughly 6 to 12 inches, and remove any debris; add compost or manure if needed.<\/p>

\u00a0<\/div>

Dig a hole slightly larger than the bellflower’s root ball, aligning the top of the roots with the ground. After filling in the hole, tamp down the soil with your hand. Give the plant a generous drink, then\u00a0add a layer of mulch<\/a>\u00a0around it to conserve moisture.<\/p>

\u00a0<\/div><\/span>

Bellflower Care Tips<\/span><\/h2>

These flowering beauties are generally low-maintenance and don’t often have major pest problems, making them a\u00a0great choice for a beginner gardener<\/a>.<\/p>

\u00a0<\/div>

Light<\/span><\/h3>

For many types of bellflower,\u00a0full sun is best<\/a>, although some woodland species perform well in part shade or even full shade. For taller types, sunshine is essential for keeping the flowers standing tall, so you don’t have to worry about staking them. Read the label of the variety you purchase for more specific care instructions.<\/p>

\u00a0<\/div>

Soil and Water<\/span><\/h3>

Most often, you’ll want to seek well-drained soil when planting bellflowers. However, some types will tolerate moist, even occasionally wet, soil. Many alpine species, such as\u00a0Campanula saxifraga,\u00a0<\/em>require very well-drained soil, making them capable of growing on rock walls or in other challenging spots. Soil pH requirements vary from species to species, though most tend to perform well in neutral soil.<\/p>

\u00a0<\/div>

\u00a0<\/div>

While you should follow the\u00a0care instructions on your plant’s label<\/a>, there are some general watering guidelines. After planting, water your bellflower at least once a week, keeping the soil damp about an inch below the surface. Early morning is the best time to give your bellflower a drink. That way, the leaves can dry off as the temperature rises.<\/p>

\u00a0<\/div>

Temperature and Humidity<\/span><\/h3>

For most varieties, warm days and cool nights yield the best growth. Some species won’t survive long if nighttime temperatures stay above 70\u2109 and conditions are humid. In regions where daytime temperatures are high, certain types may do better in partial sun, rather than full sun.<\/p>

\u00a0<\/div>

Fertilizer<\/span><\/h3>

If you notice new growth on your bellflower, it may\u00a0benefit from a light application of fertilizer<\/a>. When using granular formulations, avoid the leaves and crown to protect the plant from burns. Slow-release fertilizers should be used sparingly, because these can promote root rot in bellflowers.<\/p>

\u00a0<\/div>

Pruning<\/span><\/h3>

Deadheading, or removing spent blossoms<\/a>, can encourage some species to produce more flowers. This can be a slow process, as you should remove each blossom individually to avoid accidentally taking off new buds on the same stalk. Make sure to do your research: Some varieties shouldn’t be deadheaded after the first flush, since new flowers will soon follow. As summer progresses, you may want to trim off any foliage that is past its prime.<\/p>

\u00a0<\/div><\/span>

Pests and Problems<\/span><\/h2>

Bellflowers aren’t usually pest-prone, though they may\u00a0occasionally have issues with aphids<\/a>, snails,\u00a0slugs<\/a>, spider mites, thrips, or whiteflies.<\/p>

\u00a0<\/div>

Rust may appear as light-colored leaf spots and red-orange pustules on the underside of leaves. This is more likely to occur when conditions are damp. Water bellflowers at the base to reduce the risk of this disease, and remove any infected sections, destroying them so the disease can’t spread.<\/p>

\u00a0<\/div>

Powdery mildew, which looks like white or gray powder<\/a>\u00a0on leaves, is a fungal disease that may affect bellflowers. Eventually, infected foliage may turn brown and shrivel up. If you notice diseased leaves, pluck and destroy them. Proper spacing can reduce the risk of this problem.<\/p>

\u00a0<\/div><\/span>

How to Propagate Bellflowers<\/span><\/h2>

Depending on the type of bellflower, you can propagate your plants from seed, division, and stem cuttings.<\/p>

\u00a0<\/div>

Seed<\/span><\/h3>

Some bellflowers reseed on their own. However, if you are starting new plants from seed, note that they won’t produce blossoms until the second growing season. About 8 to 10 weeks before your spring planting date,\u00a0sow the seeds in a tray<\/a>\u00a0and cover them with seed-starting mix. Keep the soil moist and warm, between 65\u2109 and 70\u2109. Expect seedlings to emerge within 20 to 30 days. Move them to a sunny location until they’re 3 to 4 inches tall. After 3 to 4 weeks, apply fertilizer according to package directions.<\/p>

\u00a0<\/div>

Place the seedlings outdoors once they have four leaves, but don’t plant them right away. First they need to be hardened off, which means slowly acclimated to outdoor conditions. Place the tray in a protected area shielded from wind and heat. If frost is a possibility, bring the tray back indoors for the night. After a week, you can plant your seedlings in the ground.<\/p>

\u00a0<\/div>

You can also directly sow bellflower seeds outside after the risk of frost has passed.\u00a0Add organic matter to the soil<\/a>, then evenly distribute the seeds, covering them only lightly with soil. Water regularly to keep the soil moist. Note: Some types of bellflower seeds need to be cold-stratified, requiring you to plant them outside in the winter.<\/p>

\u00a0<\/div>

Division<\/span><\/h3>

There’s no strict schedule for dividing bellflowers\u2014simply do it as needed, maybe every two to five years, depending on the type. This can help stop the plant from spreading indiscriminately. Division is typically done in the fall, about four to six weeks before the first frost, though some species of bellflower do better if divided in spring or summer.<\/p>

\u00a0<\/div>

The day before you divide, give the plant a good watering;\u00a0perform the division<\/a>\u00a0at a time of day when the plant is in the shade. As you carefully dig up your bellflower, make sure you extract all of the roots. Pull or cut the clump apart into a few sections, making sure each has roots and new growth. Transplant the divided plants as quickly as possible.<\/p>

\u00a0<\/div>

Stem Cuttings<\/span><\/h3>

Bellflowers have soft stems rather than woody ones, so\u00a0cuttings can be taken from the young growth<\/a>\u00a0of the plant. Many species bloom in the summer, so cuttings should be taken in the spring. For spring bloomers, take cuttings in summer or early fall. Cut about 4 inches from the end of the stem right underneath a node. Remove the lower leaves from the stem, dip it into growth hormone, then poke the stem into a pot of growing medium. (You can use a pencil to pre-poke a hole.) After covering the pot in plastic, place it in a warm, well-lit spot.<\/p>

\u00a0<\/div>

Editor’s Note: This method isn’t recommended for all varieties of bellflower, so research your particular cultivar before propagating.<\/p>

The tall spires of\u00a0foxglove<\/a>, rising in the garden in early summer, are a sight to behold. Most types are biennials\u2014they need two years to bloom, then die in the fall. But if you can nurture a thriving stand of foxgloves, they’ll reseed so prolifically it will seem they’re perennials.<\/p>

\u00a0<\/div>

For successful growth, foxgloves must have rich, moist, well-drained soil and light shade, especially in the afternoon. (They’ll do fine in full sun in the northern third of the country.) These tall plants also need to be out of any wind. Plants may rebloom if deadheaded after the first flush of bloom.<\/p>
