A lovely bit of spring garden
I wonder how I'd extend the season? Something vigorous, to compete with the creeping phlox, although it helps that it wants to grow over the edge, towards the main light. Re-blooming daylilies for summer, I think. Peach and wine colors... Or since this is in town, maybe no deer, (the tulips wouldn't be there if there were deer.) Madonna lilies for late spring/early summer. A smaller-scale ornamental grass? Catmint?
What a charming visual gift to the passerby!
