What actually survives in a Fort Sill yard
Just PCSed to Fort Sill? Whatever grew at your last duty station, southwest Oklahoma plays by different rules, zone 7 in southwest Oklahoma, 100° summer wind off the Wichitas, red clay that cracks in August, and winters that swing 50 degrees in a day. 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.

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

All five get sold around here anyway. The nursery isn't lying to you, the label just wasn't written for southwest Oklahoma.
🌿 Hosta
A shade-and-moisture plant in a sun-and-wind town, even under a tree, the hot wind shreds and crisps it by July.

Blueberries want acid soil and gentle summers; southwest Oklahoma's alkaline red dirt and heat are a hard no.

Winter sun plus wind scalds it orange; summer heat finishes the job, there's a reason you don't see old ones here.
🌲 Emerald Green Arborvitae
The instant-privacy tree from milder places browns out in Oklahoma heat and wind, one tree at a time down the row.
🌺 Impatiens
A zone 10 shade annual, one 105° wind event and the bed is flat. Even shade doesn't save it here.
