Tricolor Sedum
Tricolor Sedum (Sedum spurium 'Tricolor') is a spreading evergreen perennial plant that forms a rosette with multi-colored foliage. Its leaves consist of fleshy fused colorful foliage that fades to a pinkish-white in full sun. As the plant matures, the rosettes form clumps and send up stalks of star-shaped pink flowers in summer. Tricolor Sedum is an easy care and versatile perennial groundcover for all types of well-draining gardens, and it creates a stunning display of colors in rock gardens, containers, and borders.
Once established, Tricolor Sedum is quite drought tolerant but benefits from regular watering during periods of drought. It should be watered deeply, but not too frequently. Water when the soil has dried out enough to form a slight crack on the surface, and then water until you see it coming out of the bottom of the pot. Once established, Tricolor Sedum can tolerate some flooding, but not sitting in water.
Tricolor Sedum prefers full sun to part shade and does best with at least 4-5 hours of direct sun per day. The true color of its foliage can only be appreciated in full sun. In areas with very hot and dry climates, some afternoon shade may be necessary. In shadier areas, the foliage may be much paler and may struggle to produce flowers.
Tricolor Sedum is hardy in USDA zones 3-9. It prefers temperatures as low as 18°F (-8°C) but can tolerate temperatures as high as 95°F (35°C). It will die off in colder climates, but may recover in spring. Avoid frost and extreme cold temperatures.
Tricolor Sedum can tolerate a wide range of humidity levels, though it prefers moderate humidity and does best when the air is not too dry. In dry conditions, the foliage may become discolored, so mist the leaves occasionally to increase humidity.
Tricolor Sedum prefers a nutrient-rich, well-drained soil. It should not be grown in heavy clay soils or soils that are too sandy. A good potting mix should include one part compost to four parts soil. The soil should be kept slightly moist but not overly wet.
Tricolor Sedum does not require heavy fertilization, but a light application of general-purpose fertilizer in early spring and again in mid-summer will benefit the plant. Avoid fertilizers with too much nitrogen, as this may lead to weak growth and make the plant more vulnerable to pests and diseases.
Tricolor Sedum is a generally pest free plant. However, it can be affected by aphids and other pests if not kept in check. Monitor your plants regularly for signs of pest infestation, such as yellowed foliage, sticky residue, or damaged leaves. If you do notice pests, you can remove them by blasting high pressure water. To prevent pest problems, keep the plant healthy by providing the right light, water, and soil conditions.
Tricolor Sedum does not require frequent repotting. It is best to repot in the spring or as needed in late winter, when the roots become so tightly packed that they circle the bottom of the pot. Make sure the new container is at least one size larger than the current one and fill it with a good, well-draining potting mix.
Tricolor Sedum requires minimal pruning. Pinch off fading flower stems and thin out crowded or excess foliage to control the shape and size. Be aware of flower stems that have died back, as they will take away from the aesthetics of the plant. For a bushier form, prune the rosettes back to a few inches above the soil level in spring.
Adding a layer of mulch can help protect Tricolor Sedum from extreme temperatures, retain soil moisture, and keep its roots cool. A two to three inch layer of shredded bark or another organic mulch is sufficient to provide the protection needed.
Tricolor Sedum can be easily propagated by cuttings. Cut a stem of the plant just above a set of leaves and strip away any lower leaves. Dip your cutting in rooting hormone, and then place it in moist, well-draining potting soil. Cover the cutting with a plastic bag to create a humid environment, and change the soil periodically to avoid fungal or bacterial growth. The new plants should be ready to transplant after 3-4 weeks.
Tricolor Sedum does not need to be staked or supported in any way as it is a low growing groundcover. Its stems should be able to reach the ground without any assistance.
Tricolor Sedum does not require a dormancy or rest period, but for best results, it should be given a period of rest in winter. Cut back on watering in the winter months and allow the soil to dry out slightly. This will help protect the plant from frost and extreme temperatures.
Tricolor Sedum is not toxic to pets, however, it may cause stomach irritation if ingested. It is always best to keep pets away from plants to prevent ingestion.
