Sedum Coral Reef - Sedum telephium Coral Reef is characterized by dark green to almost black leaves with white-flowers with greyed purple center.
Sedum Coral Reef, also called as Sedum telephium Coral Reef, Coral Reef Stonecrop, is a cultivar in the Sedum genus. This cultivar was discovered by Hubertus Gerardus Oudshoorn in the summer of 2006 at Rijpwetering, The Netherlands.
DESCRIPTION OF SEDUM CORAL REEF - SEDUM TELEPHIUM CORAL REEF
Sedum Coral Reef is a cross between Sedum telephium ‘Purple Emperor’ as the female, or seed, parent with Sedum telephium ‘Xenox’ as the male, or pollen, parent. Asexual reproduction by vegetative cuttings has shown that the unique features of this plant are stable and reproduced true to type in successive generations.
It is an evergreen perennial herb which reaching 41 cm tall by 26 cm spread with dense and bushy growth, upright and compact plant habit. The lateral branches are about 12.9 cm long, strong,smooth, glabrous, brown in color. The leaves are about 7.1 cm by 3.6 cm wide, ovate, bluntly acute apex, cordate base, irregularly and shallowly dentate margin, smooth, glabrous, pinnate venation, dark green to almost black when mature.
Sedum telephium Coral Reef blooms in summer to autumn from the 6.6 cm long, terminal compound cymes inflorecences with about 120 flowers per inflorecence. The flowers are white-colored with greyed purple-colored centers and are held on the 5.1 cm long, erect, moderately strong, smooth, glabrous, brown colored.
SEDUM CORAL REEF - SEDUM TELEPHIUM CORAL REEF CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light and exposure:
Sedum Coral Reef will tolerate partial shade (not full shade), but do best in full sun (6 or more hours of direct sun per day). The higher the better in most cases, a minimum of 50000 lux. The plant require high light to develop strong leaf coloration and will stretch badly under low light conditions. Low light levels can be offset with dry soil conditions, but only for a short period of time.
Temperature:
Sedum telephium Coral Reef can grow in USDA zone 5-9. The plant prefers the night temperatures of above 13 °C and day time temperature must be at least 18-21 °C. However, the hot days of summer will not be a problem and the temperature of 38 °C can still produce good quality plants. High temperatures and high humidity can create a lot of disease issues, so stay on the lookout.
The plant can tolerate freezing temperature. When the temperature drop below 10 °C the plant start to go dormant. If you experiment with the plant that are borderline resistant to freezing temperatures, or if you live in an area where the temperature frequently drops below freezing, then consider growing the plant in containers so you can move them indoors for protection from cold conditions.
Substrate and growing media:
Sedum Coral Reef can grow in pot, container or in garden with loose loamy, sandy, or gravelly soil with sharp drainage. Unglazed clay or terra cotta containers dry out more quickly than glazed pottery or plastic pots. When the soil retains too much water, as is often the case with a heavy wet clay soil, this can easily lead to root rot for the plant.
The plant in containers do require little more care than those in gardens. Repot your plants when they outgrow their current pot by moving them out to a larger container to hold the plant better. Spring is the best time to repot.
Watering:
Sedum telephium Coral Reef are drought-tolerant but do need some water. They do their best with regular watering from spring through fall. Water thoroughly and wait for the soil to dry out before watering again. Young plant will need supplemental water for the first couple of weeks to establish roots. Established plants, as long as your area gets rain every couple of weeks at the least, shouldn’t need any extra watering. Avoid wetting the leaves, stems, and flowers when watering. In winter, water just enough to keep your plants from shriveling.
Fertilizer:
Sedum Coral Reef typically needs no supplemental fertilization and can tolerate nutrient-poor soil. In fact, if the soil is too rich, this can cause weak, leggy growth. If you have very poor soil, mixing some compost into it will generally be enough to give your plant a boost. Chemical fertilizer can lead to stretching and flopping.
Winter period:
Care needs to be taken to avoid overwatering and over-fertilizing any of these plants especially during the short days, lower light levels, and cooler conditions of winter.
Covering the plant with a layer of straw or placing a tent made from plastic or bed sheets over the plants can protect them from sudden freezing temperatures; don't allow plastic to touch the plants, however. Remove any kind of covering as soon as the temperature warms.
Pruning:
Sedum telephium Coral Reef don't need deadheading (removing spent blooms), and they often look good even into winter. However, extreme heat and a lack of sunlight both can cause the plants to get a bit leggy. Cutting back the plants after they are done flowering can help to maintain their shape and encourage bushier, sturdier growth.
Pests and diseases:
If over watered or overcrowded, the plant may be subject to infestation by scale insects and/or mealybugs. Slugs and snails may also be problematic outdoors. As with all succulents, overwatering, overcrowding and lack of good air circulation can lead to root and stem rot. To avoid these problems, be sure to give your plants plenty of space to grow and spread. Use an appropriate pesticide to deal with mealybugs and scale insects indoors. Outdoors, encourage natural predators, such as ladybugs and lacewings. Pickoff slugs and snails by hand. Thin plants to reduce hiding places and improve air circulation. Reduce watering to make the environment less welcoming to slugs and snails. Crushed eggshells and/or diatomaceous earth sprinkled on the ground around affected plants may discourage these gastropods.
Propagation:
Sedum Coral Reef is very easy to propagate either by stem cuttings or division. For a stem cutting, take cuttings in spring when the plants are in the period of active growth, simply trim off a portion of stem from a healthy plant that's roughly 3 to 6 inches long, and remove the leaves on the lower half. Then, plant the cut end in soil wherever you wish. These prolific stems often will send out roots even if they're just lying on top of soil, but planting them will give them a better shot at healthy growth.
Each leaves could potentially become a new plant. Choose healthy leaves, remove them from the plant, and allow them to callus for several days. Place the leaves on a well-draining soil mix and keep the soil slightly moist. They should be well rooted after about 2 to 3 weeks, with new plantlets forming at the base.
To propagate by division, gently dig up a mature plant, and carefully pull apart the roots to separate it into sections. Then, simply replant the sections, making sure the top of the root ball is level with the soil line. Like the stem cuttings, divided sections also will typically be quick to take root.
