What actually survives in a Joint Base Lewis-McChord yard

Just PCSed to Joint Base Lewis-McChord? Whatever grew at your last duty station, Puget Sound plays by different rules, zone 8b, but maritime 8b, the number matches Georgia and the climate doesn't: nine months of drizzle, a bone-dry cool summer, and rarely a week above 80. Here's the straight list, from Sprigwise, a veteran-founded app that matches plants to yards for a living.

Every plant below is one of the 500 species in our fact-checked database, no guesses, no filler.

Ten that make it here

Full disclosure: "makes it" still means you water it through its first summer. After that, these mostly fend for themselves.

Five that will break your heart

All five get sold around here anyway. The nursery isn't lying to you, the label just wasn't written for Puget Sound.

Crape Myrtle

🌺 Crape Myrtle

Lagerstroemia indica · Tree · Zones 7–9

Zone 8 on the tag, but crape myrtles run on Southern heat, in a cool Puget Sound summer it sulks, mildews, and barely blooms.

Tap nothing. This one fails here.

Lantana

🌼 Lantana

Lantana camara · Groundcover · Zones 8–11

That 'zones 8–11' label is written for the South, here the cool summer starves it and the wet winter finishes it.

Tap nothing. This one fails here.

Texas Sage (Cenizo)

💜 Texas Sage (Cenizo)

Leucophyllum frutescens · Shrub · Zones 8–11

A desert shrub that reads 8b and thinks El Paso, nine months of Puget Sound rain rots the roots long before any freeze matters.

Century Plant

🌵 Century Plant

Agave americana · Succulent · Zones 8–11

Handles 15°F in Arizona, dies at 40°F in a Washington November, it's the winter rain, not the cold, that kills it.

Tomato

🍅 Tomato

Solanum lycopersicum · Edible · Zones 2–11
