A lovely bit of spring garden

I took this photo a couple of years ago in Nevada City. Must have been about this time of year, since the creeping phlox are sheets of color around town now, and some smaller tulips are blooming.

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!
