We have quite a bit of columbine (Aquilegia) growing in our yard. Many of the plants are seedlings and most look something like this. There are lots of quite fancy and brightly colored columbines among the 60 or 70 species (and many more varieties) but we’re happy enough with the slightly more staid, darker colors. Backlit by the sun the red comes alive and is quite bright. Growing mostly in the shade, however, it rarely gets this treatment. Still, it’s a good plant to have and isn’t generally bothered by rabbits or deer.
