Sempervivum Oddity Summary

Sempervivum Oddity Physical Characteristics

This is an evergreen rosette-forming plant that has a mat-forming habit. Its clustered leaves are very dense, which is different from the normal sempervivum leaves that are broad and pointy. Instead, this variety’s leaves are folded along their leaves. These leave’s edges sometimes have purplish tips making them look like cigarettes.

The density of the plant is such that one rosette can have up to 50-60 leaves. It blooms in summer, producing pink star-shaped flowers. These flowers have flat cymes, and they grow on hairy stalks.

Sempervivum Oddity Care

It is a typical succulent that doesn’t require much water to grow or survive. Water it during spring and summer but refrain from watering it in winter since the plant is usually dormant.

In summer, when the sun is hot, ensure the soil is constantly moist. However, it shouldn’t get soaked. Soaked pottage makes the plant susceptible to root rot. The balance between keeping your substrate moist and protecting it from waterlogging depends on the type of pottage you use. A substrate rich in gravel ensures that most of the water passes through, leaving only moisture on the soil.

If growing it in a pot, ensure it has sufficient drainage holes to allow the water to pass through after giving the plant a drink. An unglazed terracotta pot is ideal as it is breathable, allowing the roots to get enough oxygen. The pores on the surface of the unglazed pot allow faster evaporation of any extra moisture in the pottage.

It will give you the best results if you expose it direct morning sun and shield it from the scorching afternoon sun. You can feed the succulent some potassium and phosphorus-rich fertilizer once during the growing season. Too much nitrogen can cause the leaves to get soggy. Also, a liquid, slow-release fertilizer is the best for feeding this succulent. 

DO YOU KNOW? Caring (propagating, pruning/trimming, beheading, watering, …) is a set of skills that is applicable to almost every succulent. Read the in-depth succulent care guide right here >>

Sempervivum Oddity Growth

It is a prolific off-setter, and you can, therefore, get your pups from the base of this plant for propagation. Plant these offsets as for daughter plants. Also, you can propagate by seed if any have grown to maturity in plants in your garden.

Pruning is not necessary for this plant’s general well-being. You want to keep the leaves as intact as possible to keep the rosettes in their pristine beauty. Repotting is only done when the subject plant has outgrown the pot or if the pottage has been depleted of nutrients or gravel.

Mealybugs, aphids, and spider mites are some of the bugs that may attack them. You can protect the plant using systemic pesticides such as need oil and keeping it healthy. Contact pesticides help when you already have an infestation in your plants.
