I got a downy lobelia, from a local nursery, and planted it in my bog garden, it seems a bit leggy, probably from insufficient light, will be moving to an area with more sun.

I've since found the plant growing wild in the edge of the woods around my home.

I've collected seeds from my plant, and will be trying to propagate from seeds this fall.

This is a lovely but unassuming flower. The description here says it is pink or white, but my plant grew purple flowers and all other photos I have seen are purple/blue. I wintersowed the seeds and got a very good germination rate. Blooming was second season.
