Sempervivum ruthenicum aka Russian Houseleek

Russian Houseleek’s native range is the Mediterranean.

Russian Houseleek does best in dry soil and should only be watered sparingly.

When growing the Russian Houseleek, it's important to use a potting soil that is well-draining and does not retain excessive moisture. An optimal soil mix should contain a high proportion of perlite or vermiculite for good drainage and some organic matter for nourishment. Simply add a few scoops of perlite to regular cactus soil to achieve this.

Russian Houseleek requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Russian Houseleek is always in the right place to thrive.

Russian Houseleek plants thrive in dry environments, however, if you choose to provide extra humidity or mist your plant, the lingering water on the leaves can create an ideal environment for certain types of harmful fungi.

The Russian Houseleek should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.

Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.

During the cold period, it is common for Russian Houseleek to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.
