I'm looking for suggestions on plants that can survive in my garden, where summer temperatures soar to 50°C (122°F) and winter lows can drop to about 5°C (41°F). I've been struggling to keep plants alive through the transitions, as they usually die off in either summer or winter. While I know succulents work here, I'm hoping to find some more traditional plants—like a few trees and some smaller flowering varieties that can withstand these harsh conditions. I'd prefer branching trees as opposed to the date palms I already have. Apologies if I used any botanical terms incorrectly; I'm not an expert!

Your soil sounds quite variable, which can impact plant choices. I’d recommend checking out more drought-resistant shrubs or ground covers. Something like the Texas Ranger (Leucophyllum frutescens) could thrive in your wet and sandy conditions. Just keep in mind that any plant will need some care to establish during those extreme temperatures!
Have you thought about native plants? They often adapt better to local climates. Since you're in Riyadh, consider options like the Acacia tree or other drought-resistant varieties. Also, look into flowering plants like Bougainvillea or desert marigold; they handle extreme heat and can brighten up your garden. Just ensure they get enough water to establish roots!
Definitely look into those! I’ve had success with Bougainvillea myself—they’re really resilient and add some beautiful color.

Right? If your soil retains some organic material, that's a good sign! Just make sure to amend it for drainage as well, especially in summer.
