Dry shade: 179 plants can take it, 87 you can actually buy

Dry shade is one of the hardest sites in a garden — no light, and a mature tree drinking every drop of water before it reaches anything else. The standard advice is a list of plants. The useful question is which of those plants a nursery will actually sell you, and that turns out to eliminate half of them.

The numbers

Our catalogue holds 2,169 plants with trait data quoted from the USDA PLANTS database. Filtering it for the two conditions that define dry shade — tolerates deep shade, and rated medium or better for drought tolerance — leaves 179 plants.

Then apply the filter almost nobody applies. USDA also records whether a plant is commercially available, and only 87 of the 179 are routinely available from nurseries. The other 92 are real plants with real trait data that you cannot easily buy. Restrict further to plants native to North America and 64 remain.

• 179 plants tolerate deep shade and drought
• 87 of those are routinely available — a 51% cut
• 64 are also native

Those links run the query live. If our data changes, the numbers on this page will drift from the numbers the finder returns — the query is the authority, not the sentence.

Why the gap matters more than the list

A recommendation you cannot act on is not a recommendation. We have not tried to explain why those 92 are hard to buy — we have no data on the nursery trade, and USDA's availability rating is the only sourced thing we can say about it. What we can say is the consequence: a list built purely from trait data, which is how most plant lists are built and how ours were built until we added the availability filter, sends readers looking for plants no supplier carries.

It also cuts the other way. Filtering for availability is the step that makes the remaining list short enough to be useful. Twenty-six plants you can order is a better answer than 179 you can admire.

The shortlist: 26 native plants, rated high for drought, that nurseries stock

The 64-plant native list includes everything USDA rates medium or better for drought. Tightening that to USDA's high drought rating — the strongest claim in the dataset — gives 26 plants. They are grouped below by the layer they occupy, because dry shade is usually a layering problem: something has to hold the ground while something else holds the structure. Ground cover here means what it says — under 1.5 ft, spreading across the soil; taller perennials and grasses sit in their own herb layer above it.

The canopy entries need a word of explanation, because a 90-ft oak is not a solution to shade you already have. They are here for two reasons: these are the trees that create dry shade and tolerate their own conditions, so finding one on the list may tell you what you are already gardening under — and if you are planting a new canopy on a dry site, this is the set to pick from. If your shade already exists, start at the shrub layer.
