azure stonecrop 'Sakhalin'


The Hylotelephium cyaneum 'Sakhalin', commonly known as stonecrop, features a robust and succulent set of leaves that are fleshy and tightly clustered. These leaves often sport a glaucous, or waxy, appearance, with a round to ovate shape that sometimes retain hints of blue or grayish tones, often accentuated by subtle pink edges, depending on the variety. As the seasons progress, the stonecrop may present an alluring transformation in foliage color, taking on warmer hues. The stonecrop blooms in clusters of tiny, star-shaped flowers. These flowers are generally arranged in dense groupings that stand above the foliage, reminiscent of a frothy sea foam. The flower colors can range from soft pinks to bold magentas, creating a contrasting spectacle against the cooler colors of the leaves. The stonecrop's overall appearance gives it a lush, carpet-like visual that makes it a favored choice for ground cover in gardens. Its hardy nature contributes to its attractiveness among gardeners, as it can thrive in a variety of conditions and requires relatively minimal care. This adaptable plant brings a textured, colorful presence to any planting arrangement, contributing to its popularity as a decorative and functional element in landscaping.

  • water dropWater

    The plant commonly known as Stonecrop requires moderate watering. For Stonecrop, water when the top inch of soil feels dry, typically every 1 to 2 weeks, depending on the climate and environmental conditions. It's crucial to avoid overwatering, so use approximately half a gallon per watering for a medium-sized plant, ensuring water penetrates the soil but does not leave the pot waterlogged. During the growing season in spring and summer, increase the frequency of watering, but cut back during the dormant season in fall and winter. Always check the soil's moisture level before watering to adjust the amount as necessary.

  • sunLight

    Stonecrop thrives best in full sun to partial shade conditions. It should be placed in a spot where it can receive at least 6 hours of direct sunlight per day. However, if you are in a particularly hot climate, provide some afternoon shade to prevent scorching. Stonecrop prefers bright light to grow compact and healthy but can tolerate some light shade.

  • thermometerTemperature

    Stonecrop prefers a temperature range of 65 to 75 degrees Fahrenheit during its active growing season, however, it can withstand temperatures down to 30 degrees Fahrenheit during its dormant period. Avoid exposing Stonecrop to temperatures above 90 degrees Fahrenheit for prolonged periods as it can stress the plant. The ideal conditions for this plant are moderate, consistent temperatures within the preferred range.

  • scissorsPruning

    Pruning Stonecrop encourages healthier, bushier growth, and helps to prevent pest infestations and diseases. Prune the plant in early spring to remove dead or damaged leaves and to shape the plant. Cut back up to one-third of the plant to promote new growth. Pruning can also be done after flowering to tidy the plant and maintain its form.

  • circleLife cycle

    Hylotelephium cyaneum 'Sakhalin', commonly known as Sakhalin stonecrop, begins its life cycle when seeds germinate in early spring, typically after the last frost, in well-draining soil with plenty of sunlight. The seedlings emerge and develop a root system and fleshy leaves, characteristic of succulents. Throughout the growing season, the plant grows rapidly, forming a thick, mat-like ground cover. In late summer to early fall, Sakhalin stonecrop produces clusters of star-shaped flowers, attracting pollinators such as bees and butterflies to the garden. After flowering, the plant sets seeds, which can be dispersed by wind or by falling to the ground near the parent plant. During winter, the above-ground parts of Sakhalin stonecrop may die back, especially in colder climates, but the plant will regrow from its root system come the next spring, repeating its life cycle.

      Late Spring-Early Summer

    • Propogation: The most popular method of propagating Hylotelephium cyaneum 'Sakhalin', more commonly known as Stonecrop, is through stem cuttings. In the spring or early summer, when the plant is in its active growing phase, select a healthy-looking stem and cut a 3 to 4 inch (approximately 7.5 to 10 centimeters) portion just below a leaf node. Let the cutting dry for a day or two to allow the cut end to callus over, which helps prevent rot when planted. Plant the cutting in a well-draining soil mix, making sure to bury the calloused end about an inch (2.5 centimeters) deep. Water sparingly until you notice new growth, indicating that the roots have formed. This simple method is effective and creates a new Stonecrop plant that will be genetically identical to the parent.
