Mauve Bell: A Tropical Perennial for Pacific Gardens
If you’ve been searching for something a little different to add to your garden, you might have stumbled across the mauve bell (Clitoria guianensis). This lesser-known perennial herb brings a touch of tropical charm to the right growing conditions, though it’s definitely not your everyday garden center find.

What Exactly is Mauve Bell?
Mauve bell is a perennial forb – basically a soft-stemmed plant that comes back year after year without developing woody tissue like shrubs or trees. Think of it as the herbaceous cousin in the plant world, keeping things green and leafy rather than branchy and woody.
This plant belongs to the legume family, and while it shares the Clitoria genus with the more famous butterfly pea flower, mauve bell has its own unique characteristics that set it apart from its showier relatives.
Where Does Mauve Bell Come From?
Here’s where things get interesting – mauve bell isn’t actually native to North America. It’s an introduced species that has found a comfortable home in parts of the Pacific Basin, particularly in Guam and Palau. The plant has managed to establish itself and reproduce on its own in these tropical island environments.
Should You Grow Mauve Bell in Your Garden?
This is where we need to have an honest conversation. While mauve bell isn’t currently listed as invasive, its status as a non-native species means we should approach it thoughtfully. Here are some things to consider:
- Limited information is available about its growing requirements and garden performance
- It may not provide the same ecological benefits as native plants
- Native alternatives might be better choices for supporting local wildlife
Growing Conditions and Care
Unfortunately, detailed growing information for mauve bell is quite limited. Based on its established presence in tropical Pacific locations, we can make some educated guesses about its preferences:
- Likely prefers warm, tropical to subtropical climates
- Probably needs consistent moisture
- May require protection from cold temperatures
- As a forb, it would benefit from well-draining soil
Without more specific cultivation information, growing mauve bell would be somewhat experimental, which might appeal to adventurous gardeners but could frustrate those looking for reliable garden performers.
Consider Native Alternatives
Given the limited information available about mauve bell and its non-native status, you might want to explore native alternatives that offer similar benefits:
- Look for native legumes in your area that support nitrogen fixation
- Consider native wildflowers that provide reliable blooms
- Choose native perennials that support local pollinators and wildlife
The Bottom Line
Mauve bell represents one of those intriguing but mysterious plants that occasionally cross a gardener’s path. While it might be tempting to try something unusual, the lack of detailed growing information and its non-native status suggest that your gardening energy might be better invested in native plants with known benefits and growing requirements.
If you’re drawn to unique legumes or tropical-looking perennials, consider researching native options in your area first. Your local native plant society or extension office can point you toward interesting native alternatives that will thrive in your specific conditions while supporting the local ecosystem.
Sometimes the most responsible gardening choice is knowing when to pass on a plant – even when curiosity is calling!
