Sempervivum ‘Pacific Blue Ice’, commonly known as Hens and Chicks, is a succulent perennial that captivates with its rosettes of silvery blue leaves accented with rosy-pink to burgundy shades in cooler temperatures. As a resilient plant, it forms a mat that serves as a year-round garden interest, requiring little attention once established. Its evergreen nature and adaptability to various conditions make it a favorite among gardeners seeking low-maintenance yet attractive plants.
Your ‘Pacific Blue Ice’ will reach its peak ornamental value in the summer when it sends up a thick flowering stalk from the center of the hen rosette, culminating in a display of showy starry, pink flowers. Although these plants are monocarpic, meaning each rosette flowers once and then dies, they offset this by producing new rosettes around the ‘hen,’ thereby continuing the life cycle and filling out your garden space.
Caring for Sempervivum ‘Pacific Blue Ice’ entails situating it in well-draining soil, incorporating gritty materials like sand to ensure optimal growing conditions. It thrives in both containers and rock gardens, and its high frost tolerance enables it to withstand harsh winters. Always remember to protect your succulent from excessive water to prevent rot, ensuring a thriving and stunning display for your garden.

Care and Maintenance
Sempervivum ‘Pacific Blue Ice’, also known as Hens and Chicks, thrives with minimal attention, but there are key aspects of care that ensure a healthy and vibrant plant. Pay special attention to propagation methods, pest and disease prevention, and repotting techniques for optimal growth.
Propagation
To propagate Sempervivum ‘Pacific Blue Ice’, wait for the plant to produce offsets, also referred to as “chicks”. These offsets can be easily separated from the mother “hen” once they have formed their own roots. Gently twist the chick away from the parent rosette and replant in well-draining soil, ensuring that they are not situated too deeply.
Pests and Diseases
While generally pest-resistant, Sempervivum can be susceptible to:
- Aphids: Remove by spraying with water or using insecticidal soap.
- Mealybugs: Apply alcohol with a cotton swab to infected areas.
- Vine Weevil: Treat with beneficial nematodes or chemical solutions.
- Rust: Minimize by ensuring good air circulation and avoid overhead watering.
It’s also drought tolerant and deer resistant, adding to its low-maintenance appeal.
Repotting and Division
Repot your Sempervivum when the container is crowded or every few years to refresh the soil. This will help prevent root rot and encourage healthy growth.
- Gently remove the plant from its pot.
- Inspect the roots, trim any that are dead or rotting.
- Place in a new pot with fresh, well-draining compost, ideally with 25 to 50% sand for grit.
- Water sparingly to allow roots to establish.
Remember, your Sempervivum ‘Pacific Blue Ice’ is suitable for rock gardens and containers. Fertilizer is not necessary, as these hardy plants are adapted to thrive in nutrient-poor soil conditions. Do repot and divide every few years to maintain plant health and avoid overcrowding.
