Angelina stonecrop (Sedum rupestre 'Angelina') is a perennial, evergreen succulent that forms a low-growing mat. The name "stonecrop" comes from Middle English and refers to the plant's ability to grow in rocky, gravelly areas. This plant features chartreuse or golden needle-like foliage, depending on how much sun it gets (more sun results in golden leaves). It sports tiny yellow flowers throughout the summer. And in the fall, the foliage takes on an orange or rust tone.

How to Grow Angelina Stonecrop
Angelina stonecrop is a fast-growing ground cover that stays short (around 6 inches tall) and quickly spreads to form a mat. Sunshine and good drainage are key to this plant's success. Because of its chartreuse or golden color, it looks especially good when combined with plants that have dark foliage. Mass the plants together for use as a ground cover or perennial border. Angelina stonecrop also makes for a nice rock garden plant and can be placed between stones in a retaining wall. Plus, you will see Angelina stonecrop planted in patio containers and hanging baskets.
Grow Angelina stonecrop in full sun to partial shade. Its golden foliage is promoted by a location in full sun.
This plant prefers a well-draining planting location with a neutral soil pH. It does best in sandy and gravelly soils that aren’t very fertile. Its roots are shallow, but they’re able to spread through small crevices in rocky terrain.
Angelina stonecrop needs regular watering after you first plant it. But it is a drought-tolerant ground cover once established. In fact, heavy clay soil or other waterlogged sites can kill the plant. However, Angelina stonecrop grown in a container might need more frequent waterings than if it were planted in the ground.
Temperature and Humidity
Angelina stonecrop is somewhat tolerant to cold weather. It can handle temperatures several degrees below freezing and still bounce back just fine during the growing season. It also tolerates heat and humidity well, as long as it’s not stuck in standing water.
Stonecrop plants generally prefer lean soil, so fertilizer usually won't be necessary for your plant. Chemical fertilizer can cause Angelina stonecrop to stretch and flop. Thus, if your soil is lacking nutrients, consider using compost instead.
Propagating Angelina Stonecrop
Angelina stonecrop plants are easy to propagate by rooting. In fact, stems that break off from the main plant through natural occurrences often root all by themselves. If you're looking for a plant that's well-behaved and doesn't spread into neighboring garden areas, Angelina stonecrop might not be for you.
To purposely propagate your plant, snip off a piece of stem that’s around 2 to 5 inches. Then, plant it in a well-draining potting mix, and keep the soil moist while you’re waiting for roots to take hold. After around two to three weeks, you should feel resistance when you gently tug on the stem, meaning it has rooted. At this point, it’s ready for planting in the garden. Propagating with this method usually is successful at any point during the growing season, thanks to the plant's hardiness. But it's best done in late spring or early summer.
Most gardeners only prune their Angelina stonecrop plants if they feel the plants have become too large. Using hand pruners, simply trim off any overgrown stems from where you don’t want them to shape the plant. Also, remove any dead or diseased material whenever you spot it. Pruning typically can be done at any time of year without harming the plant. But as a precaution, avoid pruning during extreme hot or cold temperatures.
Furthermore, your plant might not bloom during its first year. But whenever it does bloom, it will produce clusters of star-shaped yellow flowers on tall stalks. These yellow flower clusters, which arise in the summer, are reasonably attractive. However, some gardeners find their flower stalks to be awkwardly tall. And once the blooms fade, you are left with rather ugly brown stalks, which you can prune whenever you like for aesthetic reasons.
Varieties of Stonecrop
There are several other varieties of stonecrop that are easy to grow in the garden.
- Autumn joy stonecrop (Hylotelephium 'Herbstfreude'): This stonecrop also grows in average, well-draining soil with dry to medium moisture. It reaches around 1.5 to 2 feet in both height and spread. And it features blooms in the fall that start out pink and gradually turn to a rose red.
- Blue spruce stonecrop: (Sedum 'Blue Spruce'): This cultivar has bluish foliage that grows around 6 to 9 inches tall with a 1- to 1.5-foot spread. Small, star-shaped, yellow flowers emerge in June and July. It adapts to many soil conditions, as long as there is good drainage.
- Purple emperor stonecrop (Sedum 'Purple Emperor’): This is a hybrid perennial stonecrop with dark purple foliage. It grows upright at a little more than a foot in height and spread. And it sports tiny masses of pinkish-purple flowers from around July to September.
