Now called, Hylotelephium erythrostictum â€˜Mediovariegatumâ€™. Good for dry, sunny spaces.
This variegated sedum has long been one of my favorites. It began as a “passalong” plant from a friend, and as the years went by its fine qualities slowly revealed themselves. For those qualities it gained a place among my favorites- combining good looks and usefulness.
There are many fine types of sedums, and even within this category, Sedum alboroseum ‘Mediovarigatum’, there are many improvements … but I would always hold a place for this particular strain. What are the attributes I so appreciate?
- It is a tough plant. It takes all sorts of weather and soil conditions.
- It is a pretty plant. The mounded form and the way light plays upon the foliage are two attractive qualities. It has the ability to light up an area of the garden with its pale, creamy butter-yellow variegation.
- It is an easy plant. It almost takes no care, at least no carefulness. It is easy to propagate, requiring only a single stem with little nodules of root to start a whole new plant.
- It mixes with other plants extremely well, and keeps to its own place.
Sedum Alboroseum Mediovarigatum has fleshy oval leaves with a slight wave to them. The plants are mounds of about 1 ft. to 3 ft. high and wide.
In the alboroseum ‘Mediovarigatum’ form, it is the leaves with their inner portions of creamy buttery yellow outlined in soft medium green that are the attraction. They look good all season from their budding sprouts in spring to the autumn, when they turn clear yellow tints.
Flowers in late summer and early fall, the bloom is a pale pink flower cluster, with a pallid look.
Full sun to part shade light conditions; moisture levels from dry to medium. Prefers sun, and medium moisture conditions. Perennial plant hardy in Zones 4-9
Take cuttings almost any time during the growing season; division is very easy, too, and at most any time.
One of the few drawbacks of this plant are when they have too much of a good thing; too much moisture, or soil that is too fertile, and the plants will grow fast and “splay” unattractively. You simply divide into smaller, new plants to resume the full mounds of succulent leaves.
In the Landscape
Often seen in the New American style of garden plan, this plant works well with grasses, rudbeckias, asters, and Russian Sage, Perovskia. It can be grown covering a large area, almost as a groundcover, although it does not spread on its own. Good in tough places that are dry or have poor soil.
The seedheads left for winter interest create a landing place for frostings of snow. Birds may eat the seeds. 
Also called Stonecrop.
Leaves are edible– raw or cooked: The leaves are very mucilaginous and have a fairly bland flavor.
Very attractive to both bees and butterflies.
