  •   Sempervivum 'Kramer's Spinrad' is a hardy succulent in the Crassulaceae family, bred as a compact cultivar for collectors and beginner plant growers alike. This genus originates from mountainous regions of Europe and Asia Minor, where plants endure rocky scree beds, poor soils, and dramatic temperature swings. It brings that same rugged resilience to windowsills, patio containers, and rock gardens.

      'Kramer's Spinrad' forms tight rosettes in forest green with vivid edging. The fleshy, pointed leaves have a clean, structured appearance. It grows upright and clustering, steadily producing offsets that fill troughs and containers with satisfying density over time.

      Each individual rosette blooms once in summer, sending up tall, starry flower stalks from mature plants before making way for the healthy offsets surrounding it. To encourage blooming, 'Kramer's Spinrad' benefits from a cool night temperature drop, which signals the plant that the season is shifting.

      Move 'Kramer's Spinrad' outside in summer on a balcony or patio, where it handles wind, dry air, and light rain with confidence. It does appreciate cover from heavy, prolonged rain, which can rot the rosette crown if water pools there. Propagation is simple: detach the small rosette pups from the mother plant and pot them into gritty soil. You can leave it up to ten days without water. 'Kramer's Spinrad' is pet friendly and grows well outdoors through autumn.

  •   Sempervivum 'Kramer's Spinrad' grows well in bright indirect light and benefits from regular rotation for even, symmetrical rosette development.

      Water it deeply but infrequently, roughly every ten to fourteen days during the growing season, and less in winter.

      'Kramer's Spinrad' does best in fast-draining gritty mix, ideally cactus and succulent compost blended with coarse perlite or grit.

      It tolerates temperatures from around 25°F and handles cool indoor and outdoor conditions with ease.

      'Kramer's Spinrad' is a moderate grower that rarely needs fertilizer, though a diluted balanced feed once in spring is welcome.

      It is hardy in USDA Zones 4 through 9, tolerating frost down to around -30°F at the lower end. It grows outdoors across Montana, Wyoming, Colorado, Utah, Idaho, Oregon, Washington, Minnesota, Wisconsin, Michigan, New York, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Missouri, Kansas, Nebraska, South Dakota, North Dakota, Kentucky, Virginia, West Virginia, Maryland, Connecticut, Massachusetts, Vermont, New Hampshire, Maine, New Jersey, Delaware, Rhode Island, Tennessee, North Carolina, Arkansas, and Oklahoma. It also grows well in warmer reaches of Zone 9, including parts of California, Texas, Arizona, Georgia, and South Carolina, with good drainage and afternoon shade during the hottest months.

    🌵 For Succulents
    When your package arrives, you may notice a bit of loose soil in the box. This is completely normal during shipping.
    Please remove your plants from their packaging right away and follow the care instructions included with your order. Succulents prefer to dry out between waterings, so only water when the soil is completely dry.
    Succulents are resilient plants and typically recover quickly once they settle into their new environment. Give them a few days to adjust before placing them in direct sunlight, and avoid fertilizing right away.
