Echeveria rubromarginata is a succulent that belongs to the Crassulaceae family. One of the names considered to be a synonym for it is Echeveria gloriosa.
This is a succulent that grows very slowly. The rosettes grow on very small and short stems. The leaves are gray-green with red margins.
The rosettes can grow up to a diameter of 8 inches. They grow alone, but at times, a few offsets grow along as well. The flowers grow on stalks that are 3 feet long. These flowers are yellow in color on the inside and reddish-pink on the inside.

Echeveria rubromarginata Care Guide
Echeveria rubromarginata requires a substantial amount of light in order to thrive. They should receive at least four to five hours of bright, direct light on a daily basis. Placing your plant outdoors during the summer months will help it to thrive.
Echeveria rubromarginata that does not receive enough light will become elongated and leggy, often ‘reaching’ towards the closest source of light. It is also unlikely that they will flower. If you have your plant on a windowsill, turn the plant occasionally to ensure that all sides of your plant get enough sun.
On the other hand, too many hours of intense, direct sunlight can result in sunburn.
Echeveria rubromarginata, like most succulents, does not require much water as they store water in their fleshy leaves. Wait until the soil has dried out completely before watering your plant, and then give it a good watering, making sure the excess water drains out from the pot.
If you water too much or too little, your Echeveria rubromarginata will start to wilt, wrinkle, or drop leaves. However, it is better to err on the side of under-watering, as they can quickly succumb to root rot if overwatered. With that in mind, Echeveria rubromarginata should never be kept in damp soil.
When watering Echeveria rubromarginata, always water the soil directly and avoid allowing water to sit on the rosette of the succulent as this can lead to rot and fungal disease.
During the spring and summer, this succulent will need to be watered more frequently than it will in the winter.
How Often to Water Succulents?
Echeveria rubromarginata requires a well-draining, porous growing medium to help keep excess moisture away from the roots. Standard soil for cactus potting is sufficient for this succulent, which can be found at most nurseries and garden centers.
If growing in containers, make sure there are drainage holes in the bottom to allow water to drain from the soil. Soil that is constantly damp or doesn’t drain well will result in root rot.
6 Best Soil for Succulents in Pots
Echeveria rubromarginata thrives in hot, dry conditions. For the most part, they do not tolerate cold temperatures or cold drafts well and too much humidity can lead to root rot. Echeveria rubromarginata grows well indoors in average room conditions with around 40% – 50% humidity.
During the spring and summer months, your indoor Echeveria rubromarginata needs temperatures of between 65 and 80°F (18 – 27°C). During the winter, a few degrees lower will be ideal. Outdoors, this succulent loves warm summers of at least 19°C or 20°C.
Generally, fertilizing is not a requirement for Echeveria rubromarginata as they are accustomed to growing in nutrient-poor soil, which makes them susceptible to fertilizer burn if over-fertilized.
However, if you want to encourage healthy growth, you can use a cactus or succulent fertilizer or low-nitrogen mix that has been diluted 3 or 4 times more than the recommended dose.
Only feed a small amount every 2 or 3 weeks during the spring and summer months which is their active growing period.
Potting and Repotting
When choosing a pot or container to grow an Echeveria rubromarginata in, it is important to choose the right size. As a rule of thumb for all succulents, choose a pot that is slightly larger than the root ball. This helps to ensure the soil doesn’t stay too damp.
Echeveria rubromarginata does not require frequent repotting and should only be repotted once they have outgrown their previous container. To repot an Echeveria rubromarginata, ensure that the soil is completely dry before removing it from its potting container. Repotting in the spring is usually recommended as the plant will be entering into its active growing period.
How to Repot Succulents
Propagating Echeveria rubromarginata
Echeveria rubromarginata propagates mainly through offsets, leaf cuttings, and seeds. A mature plant will produce offsets from its main stem, which can be separated and propagated as a separate plant. Alternatively, it can be propagated through leaf cuttings.
If the succulent has already formed several rosettes, it is particularly easy to propagate. All you have to do is cut off the rosettes. The offshoots should be at least two centimeters in diameter.
The best time to cut off the rosettes is May. Pluck apart the individual rosettes, then plant them separately.
