My yellow corydalis has been growing very well and self-seeding itself along one flower bed in partial shade. I have just pulled all of it because it was seeding in my lawn 6 feet away not adjacent to the flower bed. What a disappointment becuse it flowers from spring to fall and is so colourful.

Seemingly an under-appreciated and almost unknown plant considering its long season of bloom and easy personality. A nice, delicate leaf contrast to hostas or brunnera in a naturalized, shady setting. It blooms forever and readily self seeds, with charm.

Love this plant for dry shade. The blooms last an incredibly long time, and it's now sending out volunteers. The Baltimore-Washington area is notoriously difficult for gardening so I appreciate anything that succeeds like this one does.

Serbian bellflowers have an easy, undemanding habit. Creating a stream of lavender blue, the 1-inch-diameter star-shaped blossoms bloom reliably from late spring to early fall. The foliage remains evergreen in mild winters and needs to be sheared only once in a while to keep its appearance tidy. 'Blue Waterfall' flows beautifully along bed edges and through rock gardens in full sun to partial shade.
