For along the fence Rock garden with Creeping thyme, early blue violets, fire witch, pussy toes, and succulents. Early blue violets are great for growing in rock crevices.
Great Hell Strip design - yeah, add in some allium bulbs for round balls of color.
Planting in between the sidewalk and street. Allium giganteum (Allium 'Globemaster'), steppe sage (Salvia memorosa 'Caradonna'), catmint (Nepeta x faassenii 'Walkers Low') and peat reed grass (Calamagrostis x acutiflora 'Karl Foerster').
Consider adding a living path to your landscape. Many mat-forming plants are also tough enough to tolerate light foot traffic.
