Did a web search expecting/hoping to find that based on the name, they'd be good for a rocky area I have.
The name stonecrop derives from the fact that these plants not only tolerate dry, rocky soil but positively thrive in it"
A hardy plant that grows well in shallow soil"
Low–growing sedum spreads along the ground, reaching only a few inches (or less) in height. This makes them perfect for use as a ground cover along paths, in rock gardens, or cascading down a stone wall."
Yep. It's a tough spot to try and plant anything due to not much soil. Grass and weeds manage to grow there and weed wacking them is tough because of all the rough rocks. It eats up the nylon weed wacker string. The rocks are 1-2 foot in diameter and some stick up 1 foot out of the ground. Always had a vision of having something attractive planted there, filling in between the rocks with some of the rocks jutting up out of it.
Sedum are PERFECT for rocky areas; they’re basically a ‘Rock Garden’ plant. Around here, people use them as fillers in their rock retaining walls and they look just beautiful.
The only drawback is that they might eventually creep into an area of lawn, but they pull out easily enough and you just replant them back in the rocks.
