Sempervivum 'Ruby Heart'

Sempervivum 'Ruby Heart' Echeveria Sempervivum

What is the plant

If you're not certain if what you have is a Sempervivum or an Echeveria, use this as one characteristic to give you a hint.
Sempervivum usually have tiny teeth, like a comb, along the edges of the leaves.

Sempervivum are so tough that they actually need a cold dormancy where the temperature falls well below what's comfortable for us. Fall, when the nights are getting cooler, is when they show off the amazing colors. Red edges, or plummy centers, deeper coloration or even 'watermarks' are some of the main events to look for.

Sempervivum, when a 'hen' blooms, will die after the flower ripens. This, along with the difference in the flowers themselves, is a definitive trait.

Water
Water during the summer and spring, making sure drainage is immaculate. Reduce water in the winter to monthly.

Rather than giving your succulents sips of water here and there, give them a good soaking — to the point the water runs out the drainage holes at the bottom of the pot. Be sure to empty the water that runs into the saucer beneath the plant pot. Then let the soil dry out completely before watering again.
Sunlight
Full sun. Perfect for a sunny window.
Fertilizer
Feed with a controlled-release fertilizer in the beginning of the season or weekly with a weak liquid solution. Use a balanced 20-20-20 fertilizer at 1/4 strength on mature plants, and a fertilizer with less nitrogen on young plants.

Soil
Sempervivum plants prefer well-draining compost with 25 to 50 % sand or other grit. They may grow in trays, in ground, or on wood or in rock piles

A well-drained succulent mix, with an ideal pH around 6.0 (slightly acidic).
Pruning
Sempervivum are monocarpic, which means that once a rosette flowers, it dies. Pull out the dead rosette and fill the hole with gritty soil. The plant will quickly fill in any empty spots with offsets.
Temperature
The majority of sempervivum are frost hardy but it you prefer to grow a variety that is not, plant it in a pot or flat and move indoors for winter. Prefers average summer temps (65ºF/18ºC – 70ºF/21ºC). In winter, some varieties can withstand temperatures down to freezing.
