Wildflower reports coming out of Washington state (via Oregon Wildflowers) note that one of the earliest flowers of the year, Douglas’ grasswidow, is blooming along the Catherine Creek Trail. These photographs were taken three years ago at the same site in mid-March.
The first photograph displays the typical colour of the tepals, while the second image shows a nearby paler variant. Colours of the tepals can range from white to dark-purple. Though they are most often solidly-coloured, they can also display some variegation. Paul Slichter, who runs the Wildflowers of the Columbia River Gorge, has extensive photo-documentation of tepal colour variation in the species: Olsynium douglasii. Note that Paul also took photographs from the Catherine Creek site in early March of 2012 and observed a white-flowered variant, which I suspect had finished blooming by the time I visited.
Olsynium douglasii var. douglasii has been previously featured on Botany Photo of the Day, with an entry that discusses the name and a photograph of wild-collected material grown here at UBC Botanical Garden. I suspect it will be at least a couple weeks before we see any hint of flowers from our plants.
The Burke Museum also has additional images: Olsynium douglasii, while the Garry Oaks Ecosystems Recovery Team (GOERT) has propagation information and gardening conditions: Olsynium douglasii var. douglasii.
