# Companion species

> Pick one native tree or shrub and see the plants that share its ground in the wild, live under its canopy, or pair with it in a yard.

Pick one plant and see what grows with it: the natives that share its ground in the wild, and the ones that pair with it in a yard because they want the same sun, soil and climate.

## Deerberry grows in dry uplands, sandy barrens, rocky ground and the forest understory

These natives share that ground, so they will look right together and want the same care.

## Trees to plant it under

Deerberry takes some shade, so it can live beneath these.

## How the matches are made

Every species we grow is tagged with the natural communities it lives in: floodplain forests, swamps, stream banks, rich slopes, dry ridges, sandy barrens, rocky ground, old fields, the forest understory, the mountains and the coast. Wild neighbors are the species that share one or more of those tags, with the closest matches first. Yard pairings use the plant's own needs instead: overlapping hardiness zones and soil moisture, and for the shade pairings, a size difference of at least two classes and a smaller plant that tolerates part shade or shade.

Sharing a habitat tag does not mean two plants always grow side by side, and a tag says nothing about how far apart to plant them. Use the [planting-site check](https://bluewhaletrees.com/tools/site-check/) for the spot itself, and the [growth estimator](https://bluewhaletrees.com/tools/growth/) for how much room each one will want in twenty years.
