American Brunfelsia: A Color-Changing Caribbean Beauty for Your Garden
If you’re looking for a flowering shrub that puts on quite the color show, meet the American brunfelsia (Brunfelsia americana). This Caribbean native is like having a living mood ring in your garden – its flowers literally change colors over the course of several days, creating a mesmerizing display that’s sure to be a conversation starter.





What Makes American Brunfelsia Special
American brunfelsia is a perennial shrub that typically grows as a multi-stemmed woody plant, usually reaching heights of 4 to 5 meters (13 to 16 feet) under ideal conditions. What really sets this plant apart is its remarkable flowers. The fragrant, tubular blooms start out deep purple and gradually fade to white over several days, meaning you’ll often see purple, lavender, and white flowers all on the same plant at once – hence why some folks call it the yesterday, today, and tomorrow plant.
The glossy, dark green evergreen foliage provides an attractive backdrop for the color-changing flower display, making this shrub beautiful even when not in peak bloom.
Where American Brunfelsia Calls Home
This stunning shrub is native to the Caribbean, specifically Puerto Rico and the U.S. Virgin Islands. In these tropical territories, it grows naturally in the warm, humid conditions that characterize the region.
Important Conservation Note
Before you rush out to find this plant, there’s something important to know: American brunfelsia has a Global Conservation Status of S3, meaning it’s considered vulnerable in the wild. With typically only 21 to 100 occurrences or between 3,000 and 10,000 individuals remaining, this beautiful shrub is at risk in its native habitat.
If you decide to grow American brunfelsia, please make sure you’re getting your plant from a responsible source that doesn’t harvest from wild populations. Look for nursery-propagated specimens or seeds from established garden plants.
Growing American Brunfelsia Successfully
American brunfelsia thrives in USDA hardiness zones 10-11, which means it’s best suited for tropical and subtropical climates. If you live in a colder area, don’t despair – this shrub makes an excellent container plant that can be moved indoors during winter months.
Perfect Growing Conditions
- Light: Partial shade to full sun (morning sun with afternoon shade is ideal)
- Soil: Well-draining, fertile soil that retains some moisture
- Water: Regular watering, keeping soil consistently moist but not waterlogged
- Temperature: Warm temperatures year-round; protect from frost
- Humidity: Appreciates higher humidity levels
Garden Design Ideas
American brunfelsia works wonderfully as:
- A specimen plant where its color-changing flowers can be fully appreciated
- Part of a tropical or subtropical garden design
- An accent plant in mixed borders
- A container plant on patios or decks
- A houseplant in bright, humid indoor spaces
Caring for Your American Brunfelsia
Once established, American brunfelsia is relatively low-maintenance, but here are some tips for keeping it happy:
- Water regularly during the growing season, allowing soil to dry slightly between waterings
- Feed with a balanced fertilizer during the growing season
- Prune lightly after flowering to maintain shape
- Watch for common houseplant pests like spider mites and aphids if growing indoors
- In colder climates, move container plants indoors before first frost
Wildlife Benefits
The fragrant flowers of American brunfelsia are particularly attractive to evening pollinators, including moths and butterflies. The sweet scent intensifies in the evening, making it a wonderful addition to a moon garden or evening entertainment area.

American brunfelsia is an excellent choice if you:
- Live in zones 10-11 or can provide winter protection
