Tall Agoseris: A Hidden Gem for Western Native Gardens
If you’re looking for a native wildflower that’s both beautiful and low-maintenance, let me introduce you to tall agoseris (Agoseris elata). This delightful perennial might not be as famous as some of its flashier cousins, but it deserves a spot in every western native garden. With its cheerful yellow blooms and easy-going nature, tall agoseris is like that reliable friend who always shows up when you need them most.
What is Tall Agoseris?
Tall agoseris is a native perennial forb that belongs to the sunflower family. Don’t let the scientific jargon fool you – forb simply means it’s a non-woody flowering plant that dies back to the ground each winter and returns fresh each spring. Think of it as nature’s way of giving your garden a fresh start every year!
This native beauty can grow anywhere from 1 to 4 feet tall, producing bright yellow, dandelion-like flowers that bloom from late spring through summer. While it may have been known by the synonym Stylopappus elatus in the past, today we celebrate it as Agoseris elata.
Where Does Tall Agoseris Call Home?
Tall agoseris is a true child of the American West, native to both Canada and the lower 48 states. You’ll find this hardy plant naturally growing across British Columbia, California, Nevada, Oregon, and Washington. It’s perfectly adapted to the diverse climates and conditions found throughout these regions.
