Scouler’s Popcornflower: A Delicate Native Annual for Wildflower Gardens
If you’ve ever wondered about those tiny white flowers that pop up in moist meadows and along stream banks, you might be looking at Scouler’s popcornflower (Plagiobothrys scouleri). This charming little annual is one of those understated natives that deserves a closer look – and perhaps a spot in your garden.
What is Scouler’s Popcornflower?
Scouler’s popcornflower is an annual forb, which is just a fancy way of saying it’s a non-woody herbaceous plant that completes its life cycle in one growing season. Like other members of the borage family, it produces small white flowers arranged in distinctive coiled clusters that unfurl as the plant blooms. The popcornflower name comes from these tiny white blooms that can remind you of scattered kernels of popped corn.
Where Does It Naturally Grow?
This native beauty has quite an impressive range across North America. You’ll find Scouler’s popcornflower growing naturally throughout much of western North America, from British Columbia down to California and eastward across the Great Plains. It’s native to both Canada and the lower 48 United States, though it’s probably been introduced to Alaska rather than occurring there naturally.
The plant grows in an impressive list of states and provinces: Alberta, British Columbia, Manitoba, New Brunswick, Ontario, Quebec, Saskatchewan, Yukon, Alaska, Arizona, California, Colorado, Idaho, Illinois, Maine, Minnesota, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oregon, Pennsylvania, South Dakota, Utah, Washington, Wisconsin, and Wyoming.

- Light: Full sun to partial shade
- Soil type: Adaptable to various soil types, particularly those that stay moist

Wildlife and Ecosystem Benefits
Like many native wildflowers, Scouler’s popcornflower plays an important role in supporting local wildlife.

Is This Plant Right for Your Garden?
Scouler’s popcornflower is an excellent choice if you’re looking to create or enhance natural areas in your landscape. It’s particularly well-suited for gardeners who want to support native ecosystems without a lot of ongoing maintenance. However, keep in mind that as an annual, it won’t provide the permanent structure that perennial plants offer.
This delicate native is perfect for those who appreciate subtle beauty and want to create authentic regional landscapes. While it may not have the showstopping presence of larger wildflowers, Scouler’s popcornflower offers its own quiet charm and valuable ecological benefits.
