Common Houseleek - Sempervivum tectorum 'Hens and Chicks'

Introducing the Sempervivum tectorum, also known as common houseleek, which is a popular mat-forming variety of Hen and chicks Sempervivum genus. With its rosette-shaped clusters of fleshy leaves and its ability to produce numerous offsets, the house leek plant embodies the classic hen and chick growth pattern.   Native to the mountains of Southern Europe, the Sempervivum tectorum has several other names such as roof houseleek, St. Patrick cabbage, bullocks eye, Jupiter's beard, thunder plant, and live forever. These names highlight different aspects of the house leek plant, such as its ability to grow on rooftops (roof houseleek), its association with the Irish holiday (St. Patrick cabbage), or its resilience and longevity (live forever).   Sempervivum tectorum is a succulent with thick, fleshy green leaves, variably tinged with red and purple tips. It grows 4 inches in diameter and produces offsets attached to the mother rosette by horizontal stems. The Sempervivum tectorum flowers produce tall, slender stalks topped with clusters of small, star-shaped blooms. In the summer, it produces red-purple flowers. After flowering, the individual rosettes die, leaving the chicks to fill the space and spread, hence the common name of hens and chicks. This Sempervivum tectorum plant is commonly used in rock gardens, as a border front, in rock crevices, along stone walls, as a small area of ground cover, and as an edging or foundation. It makes an excellent container plant and can be planted in rock walls for a balance of drainage, radiant heat, and root protection. When grouped together or massed, as in a small area ground cover, hens and chicks flourish.  When and How to Water Your Common Houseleek  When it comes to watering your Sempervivum tectorum, you don't want to overwater it and risk root rot, but you also don't want to let it completely dry out. The Sempervivum tectorum prefers watering once every 1-2 weeks in the growing season, and once every 4-6 weeks in the dormant season.   In the spring and summer, during the growing season, you can water your sempervivum once every 1-2 weeks. Make sure to water this common houseleek plant thoroughly, allowing the water to soak into the soil. But here's the trick: before watering again, make sure the soil is dry about an inch deep. This will prevent overwatering.    In the winter, when your Sempervivum tectorum plant goes into a dormant phase, you can reduce watering to once every 4-6 weeks. Remember, succulents like the common houseleek store water in their leaves, so they're pretty good at surviving dry periods. Just keep an eye on the soil moisture and adjust your watering schedule accordingly.  Light Requirements - Where to Place Your Sempervivum tectorum  When grown indoors, it's important to provide your plant with bright, indirect light. Place your plants near a window that receives plenty of sunlight throughout the day. If you don't have a window with enough light, you can also use grow lights to supplement your houseleek plants light needs. Aim for about 6-8 hours of light per day for these lovely succulents.  When grown outdoors, your Sempervivum tectorum hens and chicks love the full sun. These houseleek plants thrive in bright, direct sunlight. Find a spot in your garden or balcony where they can receive at least 6-8 hours of direct sunlight each day.  Remember, it is a hardy succulent and can tolerate some shade, but it won't grow as compact and vibrant as it would in full sun. So, if you want them to look their best, give them plenty of sunshine.  Whether you're growing them indoors or outdoors, just keep an eye on the leaves. If they start to stretch or become pale, it's a sign that they're not getting enough light. On the other hand, if the leaves turn brown or scorched, it might be a sign of too much direct sunlight.  Optimal Soil & Fertilizer Needs  The Hens and Chicks succulents prefer well-drained soils, and should be fertilized once a year in spring. A good option is sandy or gravelly soils, which you can find at your local garden center or make yourself by combining regular potting soil with sand or perlite. This mixture helps prevent water from pooling around the roots and causing rot.  Ideally, you want to use our specialized succulent potting mix that contains 5 natural substrates and organic mycorrhizae to promote the development of a strong root system that helps your common houseleek succulent to thrive.   As for fertilizing, sempervivum tectorum doesn't require a lot of nutrients. You can fertilize them sparingly, about once a year, in the spring. A balanced (5-10-5), diluted succulent NPK fertilizer can be used. Just make sure to follow the instructions and avoid over-fertilizing, as it can lead to leggy growth and weak plants.   Indoor Growing Hens and Chicks Requirements When growing indoors, your Sempervivum tectorum is quite hardy and can tolerate a wide range of temperatures, but it thrives in temperatures between 60°F and 75°F during the day. At night, they can handle slightly cooler temperatures, around 45°F to 55°F. So, keeping them in a room with moderate temperatures should work well. Also, they prefer low humidity levels, similar to what you would find in a typical indoor environment. So, you don't need to worry too much about humidity levels when growing them indoors.  Hardiness Zone & More  Sempervivum tectorum is a cold-hardy plant suitable for outdoor cultivation anywhere in the US, growing in hardiness zones 3-8.  It can tolerate temperatures as low as -30°F in winter and as high as 90°F in summer, making it ideal for outdoor gardens and handling seasonal temperature fluctuations.   They prefer lower humidity levels and can handle dry conditions.  So, if you live in a region with higher humidity, make sure to provide them with well-draining soil and avoid overwatering to prevent any potential issues.  Wildlife - Sempervivum tectorum Attracts the Following Friendly Pollinators Sempervivum tectorum is not just a visual delight but also a magnet for pollinators.
