The wild habitats each of our 414 trees and shrubs grows in, from floodplain forests to dry uplands, which the companion tool reads to match the plants.

Plants that share a habitat in the wild share a yard well. The table below gives the ground every plant in the catalog grows on, A to Z, from floodplain forests and swamps to dry uplands, sandy barrens and the forest understory. It is what the companion tool reads when it lists what to plant with what, and a name opens the plant’s page.

How to read the table

The habitats are the ones Blue Whale Trees reads from each plant page’s range and site facts, in eleven classes. They are floodplain forests, swamps and wet flats, stream banks, rich moist slopes, dry uplands, sandy barrens, rocky ground, old fields and edges, the forest understory, the Appalachians, the coast. A plant can belong to several, and most do.

The last column marks the plants on the Morton Arboretum’s list of those black walnut’s juglone harms, by species or by genus. The companion tool keeps them away from black walnut.

Habitats, A to Z

The table holds the 414 trees and shrubs we grow. The commonest class is stream banks, with 199 plants, and the rarest the coast, with 50.

What each column means

slug: the plant page’s address, https://bluewhaletrees.com/plants//
name: the common name the page uses
botanical: the botanical name
habitats: the habitat codes the plant grows in, separated by semicolons: bottomland, swamp, streambank, mesic-slope, upland-dry, sandy, rocky, old-field, understory, mountain, coastal
habitat_words: the same habitats in words, as the companion tool names them
juglone_source: true for a plant whose roots release juglone, which black walnut’s do
juglone_sensitive: true where the plant is on the Morton Arboretum’s list of plants juglone harms, by species or by genus

How the table is made

The habitats are read from each plant page’s range and site facts, and the companion tool matches plants that share them. The juglone columns follow the Morton Arboretum’s list of plants black walnut harms. The files are written from the records and checked at every release.
