Sedum Reflexum (The Blue Spruce Stonecrop)

Sedum Reflexum is also commonly called Sedum Rupestre or Jenny’s Stonecrop. It is a cold-hardy perennial succulent that is native to North America. As the succulent grows, it forms a mat shape to use it as a lawn alternative.

Jenny’s Stonecrop is a drought-tolerant succulent that can thrive in dry regions. Also, Sedum reflexum is edible and can be used in making salads, even though it slightly tastes like acid.

This article is for you if you want to know more about identifying, growing, and caring for Sedum reflexum succulents.

How to Identify Reflexum Succulents

Sedum reflexum belongs to the Crassulaceae family. It is called a “stonecrop” because it usually grows in stony areas. It is a strong, slightly upright succulent that grows up to 12 inches and produces yellow flowers that are bent in bud.

The leaves of the Sedum reflexum succulents are lush, terete, and with pointed tips. Unlike most succulents, the leaves Sedum reflexum do not form tight clusters in the summer.

Bear in mind that the Sedum reflexum succulents do not bloom in the first year. When they finally bloom, usually during the summer, they will form clusters of yellow flowers. These flowers grow on tall stalks which you may need to prune if they are out of shape.

Varieties

The plant has several varieties, and the following are some of the cultivars you can choose from.

Sedum Reflexum Blue Spruce: This is the plant to go for if you look for an excellent ground cover, especially in shady places. It is vigorous and has exceptional blue leaves, forming a thick carpet. The plant’s leaves look like a carpet of spruce needles. It blooms with yellow star-shaped flowers.

Sedum Reflexum Green Spruce: It is low growing and evergreen. Its foliage is succulent and an excellent look for a rock garden. It blooms in spring producing yellow star-shaped flowers, but its foliage is its main attraction.

Sedum Reflexum Angelina: This plant’s foliage changes color to turn into a reddish-orange hue in winter, but it is yellow for the rest of the year. It blooms in summer, producing yellow flowers which are difficult to see since their color gets lost in the yellow background of the foliage,

Sedum Reflexum Sandy Silver Cast: It has yellow leaves, but they turn purple if you expose it to intense sunlight. New leaves are, however, yellow-white even when exposed to intense sunlight. The plant, therefore, will always have several colors on its foliage.

Sedum Reflexum Care

You have to consider the following requirements to grow your Sedum reflexum succulents successfully:

Light

Jenny’s Stonecrop can be grown in partial or full sun. For the golden foliage to look its best, you need to grow the plant under direct sunlight.

Soil

Sedum reflexum needs to be planted in well-draining soil with a pH of 6.0 – 7.0 (mildly acidic to neutral). You can plant Jenny’s Stonecrop in gravelly or sandy soils, even if they are not that packed with vital nutrients.

Water

After planting the Sedum reflexum succulent, you need to water it. Once it matures, it becomes resistant to drought. However, your plant can die if the soil is waterlogged or contains heavy clay.

If you grow Jenny’s Stonecrops in a pot, you might need to water them more frequently than if they were planted in the ground.

Temperature and Humidity

Sedum reflexum succulents can be grown in the USDA Plant Hardiness Zones 3 to 9. This means that it can survive at a temperature of – 30 to 30 degrees Fahrenheit.

While this plant can withstand heat to a considerable extent, you should move it indoors during a heatwave. Also, Sedum reflexum plant can tolerate high humidity.

Fertilizer

Jenny’s Stonecrops do not need fertilizers. If the nutrients are not adequate for the plant to grow, consider using lean soil or compost. Using fertilizers for Sedum reflexum will make it stretch and grow out of proportion.

Pruning

If your Jenny’s Jenny’s Stonecrops are growing too big, you can prune them to stay in shape. Use hand pruners to trim off the stems growing out of proportion. Also, get rid of any dead material you notice on the plant.

The only time of the year you should not prune your Sedum reflexum is when the temperature is too high or too low.

Propagating Reflexum Succulents

There are three ways of propagating Sedum reflexum succulents: tip cutting, stem cutting, and seed propagation. Let us take a closer look at them:

Propagating from Tip Cutting

Propagating from tip cutting is one of the easiest ways of propagating Sedum reflexum succulents. This propagation technique involves taking the tip of a healthy leaf and sticking half of the tip in the well-draining soil. If you notice a tug in the soil after three or four weeks, that is a sign that the tip cutting is developing roots, which will become more evident in the coming days.

Propagating from Stem Cutting

To propagate Sedum reflexum succulents by stem cuttings, cut off a stem from a parent plant and plant it in the ground or a succulent pot with well-draining soil.

The best time to propagate by stem cuttings is during the spring when the plant just starts growing.

In three weeks, you will notice new tender roots spring up from the cuttings. Water the roots once a week until they mature.

Seed Propagation

To propagate Sedum reflexum from seeds, bury the seeds in moist soil and keep the pot in an environment with a temperature of 80 – 100 degrees Fahrenheit.

The downside of propagating Jenny’s Stonecrop from seeds is that seeds take a while to germinate. Also, some hybrid varieties of Sedum reflexum cannot be grown from seeds because they contain different genetic materials and the outcome is unpredictable.

Repotting

If you are growing the plant in a pot, you will need to repot it from time to time. Repotting is mainly necessitated by the plant outgrowing its pot. It is necessary; thus, you will need to repot the plant every two years or so. It may also be necessary to repot the plant if your pottage loses its porosity, which puts your plant in danger of waterlogging and root rot. The best time to repot is at the beginning of spring since that is the season of the plant’s growth, and it will get established faster.

Ensure the substrate is dry before you start repotting and get another bigger pot. The new pot in which you will plant the repotted plant should be four inches wider than the previous one. Move a flat blunt piece of metal or wooden solid spatula between the pottage ad the old pot (from where you are removing the plant). Using the spatula or metal bar this way loosens the root. After removing the roots, you should turn the pot upside down, being careful to get the substrate on your hand and protecting the plant.

Gently remove the soil while taking care of the roots not to injure them. You can carefully trim the leaves to make sure they easily fit in the new pot. Proceed to replant the plant in the new pot, and ensure it has sufficient drainage holes. The next step is to water the plant appropriately and keep it in a cool place away from direct sunlight until the plant is established in the new pot. You can move the plant to its permanent position after the roots are well established.

Sedum Reflexum Pest Problems

Sedum reflexum succulents are usually attacked by bacteria, snails, and slugs if grown in damp soil. Similarly, overwatering invites scale insects, aphids, and mealybugs to your succulents.

If you do not want to experience any trouble with insects and pests, do not overwater your Sedum reflexum succulents. Also, provide well-draining soil and adequate light for the plant.

To know if your Jenny’s Stonecrops are infested by insects, examine the plant for any trace of a honey-like substance. Also, check if the leaves of the plants are wrinkled and shriveled.

If you notice any of these signs, you can get rid of the pest by spraying isopropyl alcohol solution on the succulents. When spraying this solution, be very careful so that you do not damage the succulents’ waxy coating.

You can also use insecticidal soap to eliminate mealybugs and aphids. But bear in mind that the outer layer of the succulents can be washed away with insecticidal soaps. So, ensure you test the soap on a small part of your plant and see how it reacts before spraying the entire plant.

If you need a safer method of getting rid of insects, use a natural organic insecticide like pyrethroid.

Final Words

Sedum Reflexum, with all its cultivars and variants, is a beautiful low-lying decorative plant. The flowers are yellow for all the variants but aren’t the plant’s main attraction. Like other succulents, it is a hardy plant that requires care for watering. Too much water makes it vulnerable to root-rot and pests such as slugs.
