Sundew: The Sparkling Carnivorous Beauty for Your Specialty Garden
If you’re looking to add something truly unique to your garden, meet the sundew (Drosera) – nature’s own little jeweled predator. These fascinating carnivorous plants might be small, but they pack a big punch when it comes to garden interest and natural pest control.





What Makes Sundew Special
Sundews are remarkable forb herbs that lack significant woody tissue, meaning they stay relatively small and herbaceous throughout their lives. What sets them apart is their carnivorous nature – their leaves are covered in tiny, sticky tentacles that sparkle with dewdrops in the sunlight, creating an almost magical appearance in the garden.
These plants can be annual, biennial, or perennial depending on the species, giving gardeners options for different garden planning approaches. The sticky dew on their leaves isn’t just for show – it’s how they catch and digest small insects, making them excellent natural pest controllers.
Where Sundews Call Home
Sundews have an impressive native range across North America. They’re native to Alaska, Canada (including provinces like Alberta, British Columbia, Manitoba, and others), Greenland, Hawaii, the Pacific Basin, Puerto Rico, and St. Pierre and Miquelon. You’ll find various Drosera species growing naturally across an extensive range of states and provinces, from Alabama and Arkansas to Wyoming and Yukon, making them truly widespread native plants.
Garden Appeal and Design Role
While sundews are small plants, their aesthetic appeal is undeniable. The sparkling tentacles catch light beautifully, and many species display stunning colors ranging from bright green to deep red. They’re perfect for:
- Bog gardens and water features
- Specialty carnivorous plant collections
- Educational gardens where kids can learn about plant adaptations
- Container gardens on patios or indoors
- Rock gardens with consistent moisture
Growing Conditions: The Goldilocks Challenge
Here’s where sundews get a bit particular – they need conditions that are just right. These plants thrive in:
- Acidic, nutrient-poor soils (think peat-based mixes)
- Consistently moist to wet conditions
- High humidity environments
- Bright, indirect light
- USDA hardiness zones that vary by species (generally zones 3-11)
The key thing to remember is that sundews evolved in nutrient-poor environments, so rich garden soil will actually harm them. They get their nutrients from catching insects, not from soil.
Planting and Care Tips
Successfully growing sundews requires attention to their specialized needs:
- Water: Use only distilled water, rainwater, or reverse osmosis water – tap water contains minerals that can kill these plants
- Soil: Use a peat-based mix, typically 50% sphagnum peat moss and 50% perlite or sand
- Containers: Ensure good drainage while maintaining consistent moisture
- Light: Provide bright, indirect light – too much direct sun can scorch them
- Humidity: Maintain high humidity levels, especially for indoor growing
- Feeding: Don’t fertilize! Let them catch their own food or occasionally feed them small insects
Pollinator and Wildlife Benefits
While sundews are small, they do produce delicate flowers that can attract tiny pollinators. Many species are also capable of self-pollination, ensuring they can reproduce even in isolated locations. As carnivorous plants, they provide a unique ecological niche and can help control small flying insects in their immediate area.
Is Sundew Right for Your Garden?
Sundews are perfect for gardeners who:
- Love unique, conversation-starting plants
- Enjoy the challenge of specialized plant care
- Have or want to create a bog garden or water feature
- Are interested in native plants with a twist
- Want natural pest control with a difference
However, they might not be the best choice if you prefer low-maintenance plants or don’t have the time to monitor their specialized watering and growing needs.
With their native status across much of North America and their fascinating carnivorous lifestyle, sundews offer gardeners a chance to grow something truly special. While they require specific care, the reward of successfully cultivating these sparkling little predators makes the effort worthwhile. Whether you’re creating a bog garden or simply want to add something unique to your plant collection, sundews bring both beauty and biological wonder to any garden space.
