I have two patches of Trilliums that I have visited for 5 years and thought it would be interesting to compare pictures and timing. Both of these groupings are in Fauntleroy Park, a wildish place in West Seattle that is preserved around a creek ravine.
We have the big patch and then what I call the bouquet because of how it looks like it is in a vase. The pictures below start with my recent visit March 20th and go through each year to April 15, 2012.
The bouquet has similar history with the following pictures through the years.
This link is of last years post around these two patches. It has more information around this flower and how one should never pick them. Hunt for Trilliums
Back in 2013 I did a video about stalking the trillium. It shows what the forest looks like around the patch- hope you enjoy it again.
