Turn your sidewalk into a garden room
If you’re fortunate enough to have a sidewalk, you have the perfect spot for a garden area you can share with your neighbors. By planting both sides of my sidewalk with a mix of small trees, flowering shrubs, and perennials, I created a garden that rarely fails to slow down passersby. Since this is considered public space, it pays to keep a few things in mind when you plant this area.
• Choose trees that can mature comfortably in tight spaces. Persian ironwood (
Parrotia persica, Zones 4 to 7), Kousa dogwood (
Cornus kousa, Zones 5 to 8), and yaupon holly (
Ilex vomitoria, Zones 8 to 10) have worked well for me.
• Keep in mind that as the trees mature, your once-sunny area will become shadier and you will probably have to change some of the underplantings.
• Include lots of bulbs for early spring color. Squill (
Scilla spp. and cvs., Zones 5 to 8), daffodils (
Narcissus spp. and cvs., Zones 3 to 9), and snowdrops (
Galanthus spp. and cvs., Zones 3 to 9) are all good choices.
• Include flowering shrubs—both evergreen and deciduous—that either take well to pruning or won’t get too wide. Be keen on pruning, keeping in mind that scraggly branches can be an annoyance to those trying to park their cars.
• Add some self-sowing annuals such as spider flower (
Cleome hassleriana), cockscomb (
Celosia spp. and cvs.), or love-lies-bleeding (
Amaranthus caudatus) for a splash of color throughout the summer.
• Keep in mind that the sidewalk strip tends to dry out more quickly than the rest of the garden. Be prepared to water, plant drought-tolerant species, or consider berming this area to create a slightly raised bed.
• Design several crossover areas so that people parking in front of your house can step out onto paving or stone instead of onto plants.

Rich plantings signal an in-town oasis. Though the plantings are designed primarily to create a semiprivate front-yard garden, they look just as good from the street as from the house. (#5 on site plan)
