Smooth Goldfields: A Bright Native Annual for Wet Gardens
If you’ve ever wondered what creates those stunning carpets of golden yellow flowers in Pacific Northwest wetlands come springtime, you’ve likely spotted smooth goldfields (Lasthenia glaberrima) in action. This charming native annual brings sunshine to the soggiest spots in your garden – places where many other flowers fear to tread!
What Makes Smooth Goldfields Special?
Smooth goldfields is a native forb that calls the western regions of North America home. As an annual plant, it completes its entire life cycle in one growing season, but don’t let that fool you into thinking it’s high-maintenance. This little powerhouse has mastered the art of thriving in wetland conditions that would leave other plants gasping.
The plant produces masses of bright yellow, daisy-like flowers that create spectacular displays in spring. These cheerful blooms aren’t just pretty to look at – they’re also magnets for native bees and other beneficial insects, making them valuable additions to pollinator-friendly gardens.
Where Does It Grow Naturally?
Smooth goldfields is native to both Canada and the lower 48 states, with its natural range spanning British Columbia, California, Oregon, and Washington. In the wild, you’ll find it flourishing in seasonal wetlands, wet meadows, and the edges of ponds and streams.

Here’s where smooth goldfields really shows its unique personality: it’s classified as an Obligate Wetland plant in both the Arid West and Western Mountains, Valleys, and Coast regions. This fancy term simply means it almost always grows in wetlands – this plant has found its niche and is sticking to it!
While some gardeners might see wet, boggy areas as problem spots, smooth goldfields sees them as prime real estate. If you have a low-lying area that stays soggy, a rain garden, or a seasonal pond, this native beauty could be exactly what you need.
