The most useful thing in your yard might be a tree.

In Falls Church, a planting decision can start with a familiar question: will it look good from the street? Try adding another: what can use it?

A Washington-area study of Carolina chickadees connected residential plant choices with the food available to birds and their reproductive success. Yards dominated by nonnative plants offered less suitable habitat for sustaining the studied population. [1]

A local question with real research behind it

Narango, Tallamy, and Marra examined the relationship among plant origin, arthropod food, and chickadee population growth. Their findings support treating residential planting as a food-web decision, not simply a decorative one. [1]

The distinction matters. This research concerns an insect-eating bird in a particular suburban study system. It does not tell us that every nonnative plant is equally harmful, or that one new tree guarantees a nest.

Your autumn planning page

For a Falls Church yard, a DC courtyard, or an Annapolis garden, begin with an inventory. What trees and shrubs are already there? Which are native to your locality? How much space and light can you offer a replacement or addition?

Use those questions to prepare a conversation with a regional native-plant specialist. Ask for a botanical name, local native range, mature dimensions, and a match to your actual growing conditions. This is a planning exercise, not a universal planting calendar.

What to take away

My editorial recommendation is to make the next planting decision deliberately, with the food web in view. The evidence makes a strong case for considering native vegetation; your site conditions determine the appropriate plant. The study cannot promise the outcome of an individual garden. [1]
