Growing Scentbottle: A Fragrant Native Orchid for Specialty Gardens
Meet the scentbottle (Platanthera dilatata), one of North America’s most widespread and enchanting native orchids. Don’t let the unusual common name fool you – this elegant perennial produces tall spikes of pristine white flowers that release their sweet fragrance into the evening air, making it a true treasure for native plant enthusiasts.
What Makes Scentbottle Special
Scentbottle is a herbaceous perennial that belongs to the orchid family, and it’s quite the showstopper when in bloom. The plant produces dramatic flower spikes that can reach 2-4 feet tall, densely packed with small, creamy-white flowers. What really sets this orchid apart is its incredible fragrance – the flowers release their sweet scent primarily in the evening to attract nocturnal pollinators like moths.
As a native species, scentbottle has an impressively wide distribution across North America. You’ll find it growing naturally across Canada from British Columbia to Newfoundland, throughout Alaska, and in numerous U.S. states including California, Colorado, Maine, Minnesota, Montana, Nevada, New York, Oregon, Washington, and many others.

There are several compelling reasons to add this native orchid to your garden:

If you’re new to native gardening or looking for easier alternatives, consider starting with other moisture-loving natives like cardinal flower, blue flag iris, or swamp milkweed. But if you’re up for the challenge and have the right conditions, scentbottle can be a truly rewarding addition that connects your garden to the wild heritage of North America while supporting specialized pollinators that depend on native plants.
Remember, growing native plants like scentbottle isn’t just about adding beauty to our gardens – it’s about preserving the complex relationships between plants, pollinators, and ecosystems that have evolved over thousands of years.
