Cathedral Bells: A Quirky Succulent with a Traveling Spirit

If you’ve ever seen a plant that seems to be plotting world domination one tiny plantlet at a time, you’ve probably encountered Cathedral Bells (Kalanchoe pinnata). This fascinating succulent, also known as air plant, has earned quite a reputation for its unique ability to produce baby plants right along the edges of its leaves – nature’s own little nursery!

What Exactly Is Cathedral Bells?

Cathedral Bells is a perennial succulent that belongs to the forb herb category, meaning it’s a soft-stemmed plant without woody tissue. Don’t let the delicate-sounding description fool you – this plant is tougher than it looks. Botanically known as Kalanchoe pinnata, it also goes by the synonyms Bryophyllum pinnatum and Cotyledon pinnata, depending on which botanical reference you’re consulting.

The common name Cathedral Bells comes from its drooping, bell-shaped flowers that hang like little church bells from tall, graceful stems. These blooms typically appear in shades of pink, red, or orange, creating quite a spectacular display when the plant is happy.

Where Does It Come From?

Here’s where things get interesting from a native gardening perspective. Cathedral Bells isn’t actually native to the United States – it originally hails from Madagascar and other tropical regions of Africa and Asia. However, this adaptable plant has made itself quite at home in warmer parts of America, particularly in Florida, Hawaii, and various U.S. territories including Guam, Palau, Puerto Rico, and the Virgin Islands.

As a non-native species that reproduces spontaneously in the wild, Cathedral Bells has essentially become a naturalized resident in these areas. While it’s not currently listed as invasive or noxious, it’s worth keeping an eye on its spread in your garden.

Should You Grow Cathedral Bells?

The answer depends on your gardening goals and location. Cathedral Bells can be a fascinating addition to succulent collections and drought-tolerant landscapes, especially if you enjoy plants with unique propagation methods. However, as native gardening enthusiasts, we always encourage considering native alternatives first.

If you’re in areas where Cathedral Bells has naturalized, you might want to explore native succulents and drought-tolerant plants instead. For example, native sedums, agaves, or other regional succulents can provide similar aesthetic appeal while supporting local ecosystems.

Growing Conditions and Care

If you do decide to grow Cathedral Bells, the good news is that it’s relatively low-maintenance. Here’s what this succulent needs to thrive:

  • Sunlight: Full sun to partial shade – it’s quite adaptable
  • Soil: Well-draining soil is absolutely essential to prevent root rot
  • Water: Drought-tolerant once established; water sparingly and let soil dry between waterings
  • Temperature: Hardy in USDA zones 9b-11; not frost tolerant
  • Wetland status: Prefers upland conditions and usually doesn’t occur in wetlands

The Magic of Plantlet Propagation

Perhaps the most fascinating aspect of Cathedral Bells is its remarkable propagation method. The scalloped edges of its thick, fleshy leaves develop tiny plantlets – complete with roots and leaves – while still attached to the parent plant. These little clones eventually drop off and establish themselves wherever they land.

This unique reproduction strategy means you can easily propagate Cathedral Bells by simply removing the plantlets and potting them up. It’s like getting free plants delivered right to your doorstep – well, your garden bed, anyway!

Landscape Role and Design Ideas

Cathedral Bells works well as:

  • A specimen plant in succulent gardens
  • Container plantings for patios or decks
  • Rock gardens where drainage is excellent
  • Xeriscaping projects focused on water conservation

The plant can grow quite tall when flowering, so consider its mature size in your design. Its architectural form and interesting leaf structure make it a conversation starter, while the eventual flower display adds vertical interest to any planting scheme.

Wildlife and Pollinator Considerations

While Cathedral Bells does produce nectar-rich flowers that can attract hummingbirds and some pollinators, it’s not considered a primary pollinator plant. For maximum wildlife benefit, consider pairing it with native flowering plants that provide more substantial support for local pollinators and beneficial insects.

Final Thoughts

Cathedral Bells is undeniably an interesting plant with its unique propagation method and striking flowers. While it can make a fine addition to appropriate garden settings, remember that native plants typically offer greater ecological benefits. If you do choose to grow Cathedral Bells, enjoy its quirky personality while being mindful of its spreading tendencies – and maybe keep those plantlets from taking over the neighborhood!

Whether you’re drawn to its bell-like flowers or fascinated by its self-propagating leaves, Cathedral Bells certainly knows how to make an impression. Just remember to give it the well-draining conditions it craves, and you’ll have a low-maintenance succulent that’s sure to spark conversations with fellow gardeners.

Wetland Status

The rule of seasoned gardeners and landscapers is to choose the "right plant for the right place" matching plants to their ideal growing conditions, so they'll thrive with less work and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection is. While tags list watering requirements, there's more to the story.

Knowing a plant's wetland status can simplify the process by revealing the interaction between plants, water, and soil. Surprisingly, many popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. Also, it helps you make smarter gardening choices and grow healthy plants with less care and feeding, saving you time, frustration, and money while producing an attractive garden with greater ecological benefits.
