Falseteeth: A Unique Native Shrub for Tropical Gardens
If you’re looking for an unusual native plant with an equally unusual name, let me introduce you to falseteeth (Capparis flexuosa). This quirky moniker might make you chuckle, but this native shrub is no joke when it comes to adding character to your tropical or subtropical garden.



What Is Falseteeth?
Falseteeth is a perennial shrub that’s truly American, being native to the lower 48 states (specifically Florida), Puerto Rico, and the U.S. Virgin Islands. You might also see it listed under its botanical synonym, Cynophalla flexuosa. This multi-stemmed woody plant typically reaches about 16 feet in height at maturity, though it can grow up to 25 feet in ideal conditions.
Where Does Falseteeth Grow Naturally?
This distinctive shrub calls the warm corners of America home, naturally occurring in Florida, Puerto Rico, and the Virgin Islands. It’s perfectly adapted to these tropical and subtropical environments.
Why Consider Falseteeth for Your Garden?
Falseteeth brings several appealing qualities to the right landscape:
- Striking white flowers: The conspicuous white blooms appear in summer, creating a beautiful display
- Interesting fruits: Green, conspicuous fruits follow the flowers and persist into fall
- Dense foliage: The coarse-textured green leaves provide year-round coverage
- Native heritage: Supporting local ecosystems by choosing native plants
- Unique character: The irregular growth form adds natural, informal appeal
Growing Conditions and Care
Falseteeth is surprisingly accommodating for a plant with such specific native range requirements:
Climate Requirements
- USDA Zones: 10-11 (requires year-round frost-free conditions)
- Minimum temperature: 40°F
- Frost-free days: Needs 365 days without frost
Soil and Site Conditions
- Soil texture: Adapts well to coarse and medium-textured soils, but struggles in fine-textured soils
- Drainage: Prefers well-draining conditions
- Salt tolerance: Medium salinity tolerance makes it suitable for coastal areas
- Sun exposure: Intermediate shade tolerance, but likely performs best in full to partial sun
Water and Maintenance
- Drought tolerance: Medium drought tolerance once established
- Fertilizer needs: Medium fertility requirements
- Growth rate: Active growth period in spring
- Pruning: Low hedge tolerance, so avoid heavy pruning
Landscape Uses
Falseteeth works best in naturalistic settings where its irregular growth form can shine. Consider it for:
- Native plant gardens
- Coastal landscapes
- Specimen plantings
- Mixed shrub borders
- Wildlife-friendly gardens
Planting and Propagation
Getting falseteeth started in your garden is straightforward:
- Best method: Grow from seed, which is the primary propagation method
- Planting density: Space plants 320-1,280 per acre depending on your design goals
- Root depth: Ensure at least 24 inches of soil depth for proper root development
- Timing: Plant when soil is warm and frost danger has passed
Is Falseteeth Right for Your Garden?
Falseteeth is an excellent choice if you live in zones 10-11 and want to support native ecosystems. Its white summer flowers and persistent fruits add seasonal interest, while the dense foliage provides year-round structure. However, this plant is quite specific about its climate needs – it absolutely must have year-round frost-free conditions to survive.
If you’re outside its natural range, consider other native alternatives better suited to your local conditions. But if you’re lucky enough to garden in Florida, Puerto Rico, or the Virgin Islands, falseteeth offers a unique way to celebrate your local flora while adding character to your landscape.
Remember, this shrub has a relatively short lifespan and doesn’t resprout if damaged, so choose its location carefully and protect it from harsh conditions. With proper care and the right environment, falseteeth will reward you with its distinctive charm and native authenticity.
