Sempervivum ‘Hedgehog’

Sempervivum Hedgehog is a captivating succulent that forms beautiful densely packed round rosettes. Hedgehog is categorized as a ‘roller’ – a type of succulent that forms offsets or ‘chicks’ on top of the mother plant.

The chicks grow on stems that are quite brittle. Over time, the offsets ‘leave home’ by breaking off from the stems and rolling around until it finds new places to take root.

Sempervivum Hedgehog rosettes have green spiky leaves with burgundy-colored tips and undersides.

A Sempervivum Hedgehog can grow up to 8cm (3”) tall and 16cm (6”) wide. This winter dormant succulent blooms in its second year or third year.

Sempervivum hedgehog is sometimes referred to as Hen and Chicks and is a monocarpic succulent. Monocarpic means that the plant will die after it produces flowers.

A flower stalk shoots up from the center of the mother plant with clusters of reddish, pinkish, or yellowish star-shaped flowers. After flowering the main rosette from which the flower head sprung dies.

Sempervivum Hedgehog is a hybrid succulent and is thought to have originated from Oaxaca, Mexico; Central America, and northern South America. It is part of the Sempervivum genus from the Crassulaceae family.

How to Grow and Care for Sempervivum ( Hedgehog )

Sempervivum ‘Hedgehog’ plant

Sempervivum Hedgehogs are very easy to care for and grow. At home, they can be added to indoor container gardens and outdoor rock gardens.

It is a cold-hardy plant that can survive a temperature as low as -29°C (-20° F).


Sempervivum Hedgehog needs plenty of bright light to stay healthy. When planted outdoors, choose a spot where it can get 5 to 6 hours of Full to Partial Sun in the morning and afternoon.

Exposure to direct intense light will burn its leaves. Low light exposure will result in etiolation, where the plant will stretch out towards the light source.

Indoors, place its container near a southeast or south-facing window where it can enjoy plenty of filtered bright light for 5 to 6 hours.

To keep your Sempervivum Hedgehog happy and healthy, practice neglect when it comes to watering.

Succulents are types of plants that store water in their leaves and stems. They can survive long periods without water. For proper care, only give Hedgehog water when the soil is completely dry.

Depending on the season and the temperature in your region, it might take seven to 10 days for the soil to dry out. During winter, the soil retains moisture longer so the watering schedule will be less frequent.

In contrast, water your plant frequently during the spring and summer months because the soil dries out faster.

You can check the dryness of the soil simply by inserting a stick. If the end of the stick feels dry after you pull it out of the soil, then it’s time to give it a lot of water. Use the soak and dry method for Sempervivum Hedgehog.

Water the soil until water leaks out from under the pot. Avoid watering your plant from the top to prevent water from accumulating in between the leaves which can lead to leaf rot.

Pot and Soil

Sempervivum Hedgehog is best potted in ceramic or terracotta containers with drainage holes. These pots are made with breathable materials that allow good soil aeration and prevent plants from getting waterlogged.

Hedgehog needs well-draining soil to thrive well. Use cactus or succulent potting mix and combine it with equal parts of mineral grit such as coarse sand, perlite, gravel, or volcanic rock for better drainage.

Sempervivum Hedgehog requires little fertilizer. Feed it with a well-balanced liquid fertilizer once a month during spring and summer when it actively grows.

How to Propagate Sempervivum Hedgehog

Sempervivum ( Hedgehog ) can be propagated using its offsets and seeds. The best time to propagate this succulent is in spring or early summer.

Method 1 – Offsets

Step 1: Choose healthy offsets that have sprouted on top of the mother plant.

Step 2: Use a sterile sharp knife or pruning shears to cut off the stolon at about ½ inch from the base of the offset.

Step 3: If the offset has already rolled away from the mother plant, you can gently pull it out.

Step 4: Allow the offsets to dry for 2-3 days. After the calluses have formed, place each offset in its pot filled with cactus mix and mineral grit.

Step 5: Place the pots in a partially shaded area. Water the soil after 5 days. Once the roots have been established, you can replant them or place the pots in an area that gets plenty of indirect bright light.

Method 2 – Seeds

Step 1: Get a shallow container with drainage holes. Fill it with well-draining soil. Water the soil thoroughly.

Step 2: Press the seeds into the topsoil. Cover the tray with plastic and place it in an area exposed to filtered light. Wait 7 days before you mist the soil.

Step 3: Once the seeds have germinated, remove the plastic and place the tray in an area that gets plenty of indirect bright light.

Step 4: When the sprouts have grown big enough, transplant them to pots or garden beds.
