The small white flowers are arctic starflower (Trientalis europaea). They grow in profusion on all of my sphagnum. They produce a seed cluster that is shaped like a soccer ball. I find they grow great with all my other plants. They are so small they don't interfere with anything I am growing. That picture is from after their peak when there was only a couple left blooming.What are those Crocus like beauties?
Also you really have to zoom in on the bog barrel to see all the interesting plants. You could enter it in a local plant show.
I almost dragged my planter over to the Vancouver island rock and alpine garden society plant show that was yesterday. I ended up not wanting to go through all that bother though. Its really heavy even when the internal reservoir is drained. It is a chore to move but it would have been nice to share with others. Maybe some day when I am feeling more up to it.
