Cobweb Houseleek ‘Big Sam’ (Sempervivum) – evergreen succulent ground cover – 7 cm pot – height 10–12 cm

Yes, the Big Sam Houseleek (Sempervivum) is one of the hardiest succulent perennials available on the market. It can withstand temperatures as low as -20°C without any winter protection, making it perfectly suited to the entire French territory, including mountainous areas and regions with harsh winters. Its fleshy leaves store water and withstand repeated freeze-thaw cycles. The foliage remains all year round, even taking on highly decorative reddish or bronzed hues in winter due to the cold.

Big Sam sempervivum thrives in all the sunny, well-drained locations that most other plants refuse. It excels in rock gardens, on dry stone walls, in paving joints, along mineral borders, or on extensive green roofs. It also does wonderfully in pots or planters on south-facing balconies or terraces. Avoid shaded areas and heavy, damp soils, which promote rosette rot.

Big Sam's slipper plant multiplies entirely naturally and autonomously: each mother rosette produces stolons bearing young daughter rosettes called "chicks". Simply detach these young plants at the base of the stolon as soon as'they measure a few centimeters and replant them directly in well-drained soil or a pot with suitable substrate. This can be done from spring to'autumn, without any special tools or specific skills. The daughter rosettes'take root very quickly, often within a few weeks.

Absolutely, the Big Sam Bougainvillea is an excellent candidate for growing in a pot or planter, provided you follow a few simple rules. Choose a shallow but wide container with essential drainage holes, and fill it w'ith a well-draining mix: a lightweight multipurpose potting mix with one-third sand or fine gravel. Place the planter in th'e sunniest spot on your patio or balcony. In a pot, w'atering should remain moderate: wait until the potting mix is dry on the surface before 'watering again.

Yes, the Big Sam plant produces upright flower stalks in summer bearing pink to reddish star-shaped flowers, which are highly melliferous and appreciated by bees and other pollinators. Flowering generally takes place between June and August depending on the climate and l'exposure. It should be noted that each rosette only flowers 'once in its life before withering: t'his is a natural process called partial monocarpism. This does not harm the plant as a whole, as the numerous daughter rosettes produced by the stolons immediately take over.

The Big Sam bougainvillea is a particularly hardy plant that is not prone to diseases when grown under the right conditions. Its main enemy is excess moisture: poorly drained soil or too frequent watering causes the rosettes to rot, caused by fungi such as Phytophthora. In the event of rot, immediately remove the affected parts and improve drainage. Mealybugs can occasionally settle in the heart of the rosettes: treat with a cotton swab soaked in alcohol or a natural insecticide made with black soap.

Joubarbe Big Sam pairs beautifully with other plants suited to dry, sunny conditions. Combine it with Sedum (stonecrops), Delosperma, creeping thyme or lavender to create a vibrant, colourful rock garden. Ornamental grasses such as Festuca glauca or Carex buchananii provide an attractive textural contrast to its dense rosettes. In a contemporary planter, combine different cultivars of Joubarbe in various shades for a very on-trend graphic, minimalist effect.
