Sedum ‘Thundercloud’

Since Sedum ‘Thundercloud’ reaches a mature width of 18 inches, you should space them at least 18 inches apart if you want them to grow as individual specimens, or slightly closer if you prefer them to knit together into a solid groundcover.

This variety is excellent for containers. Because it is drought-tolerant and compact, it thrives in pots as long as you use a well-draining potting mix and ensure the container has adequate drainage holes.

Yes, Sedum ‘Thundercloud’ is quite hardy and is rated for USDA zones 3 through 9. It is a perennial that will return each spring, though its foliage may die back or thin out depending on the severity of your local winter.

Once established, this plant is highly drought-tolerant and requires very little supplemental water. You should only water it during extended dry spells, as it prefers to stay on the drier side and will not tolerate sitting in soggy or waterlogged soil.

While no plant is 100% deer-proof, this Sedum is considered deer-resistant. Its texture and taste are generally unappealing to deer, making it a safer choice for gardens that frequently deal with browsing wildlife.

The most important factor is drainage. If you have heavy clay soil, amend it with grit, sand, or compost to improve drainage, as this plant will rot if its roots remain wet for too long.
