If grown well, its color turns very red, and it is precisely this red that attracts many succulent lovers. So how do you grow Sedum rubrotinctum 'Aurora' to a bright red color? What are the cultivation methods and care tips? What is the difference from Sedum rubrotinctum 'Aurora' Variegata?

Introduction to Sedum rubrotinctum 'Aurora'

Sedum rubrotinctum 'Aurora', also known as Christmas Cheer or Earring Grass, is a succulent and fleshy plant of the genus Sedum in the Crassulaceae family.  The leaves of Sedum rubrotinctum 'Aurora' are fleshy, elongated oval, about 1 cm long, and alternate. The flowers are yellow and star-shaped. In autumn and winter or under strong light, the leaves partially or entirely turn bright red. The leaf tips are slightly transparent, and at this time the leaves are red and green alternating, with vivid colors, like a rainbow or jade, hence the name Hongzhiyu (Rainbow Jade). Its plant reaches 10-20 cm in height and is much branched. Its fleshy leaves are enlarged and alternate, cylindrical to ovate, 2 cm long, with green leaf color, glossy surface, and no white powder. Under conditions of sufficient sunlight, the leaves of Sedum rubrotinctum 'Aurora' turn from green to reddish-brown, and the small flowers are pale yellow-red.

How to Grow Sedum rubrotinctum 'Aurora' to a Bright Red Color

What is rather special about Sedum rubrotinctum 'Aurora' is that it is not afraid of full sun. Unlike many succulent plants, the color of Sedum rubrotinctum 'Aurora' becomes redder the more it is exposed to the sun. So in the hot summer, there is no need to worry about Sedum rubrotinctum 'Aurora' getting sunburned, nor is there any need to deliberately shade it. If Sedum rubrotinctum 'Aurora' is kept growing in a semi-shaded environment for a long time, its leaves will turn green and become less attractive than when red. Sometimes, in a single pot of Sedum rubrotinctum 'Aurora', due to differences in the intensity and duration of sunlight received, the leaf color will be partly red and partly green; new leaves, due to shorter light exposure, often have red tips while the rest remains green. It likes a warm environment with a pronounced day-night temperature difference. It has strong adaptability to temperature and can grow well between 10°C and 28°C.

Cultivation Methods for Sedum rubrotinctum 'Aurora'

Sedum rubrotinctum 'Aurora' likes a warm environment with a pronounced day-night temperature difference. It has strong adaptability to temperature and can grow well between 10°C and 28°C. In autumn and winter, as temperatures drop and light intensity increases, the fleshy leaves gradually turn red, so artificially lowering the temperature during cultivation can enhance its ornamental value.

Temperature: Sedum rubrotinctum 'Aurora' has very strong adaptability to temperature. It prefers an environment with a large day-night temperature difference, and a growing temperature of around 10°C-28°C allows it to survive very well. In autumn, artificial cooling can be used to maintain the emerald green color of the leaf surface, effectively enhancing its ornamental value. At the same time, in winter, the temperature can be kept above 5°C.

Light: Sedum rubrotinctum 'Aurora' loves sunlight. In winter, it can be placed on a balcony to absorb sunlight. In summer, it can be given half-day sun or partial shading; at noon in summer, direct sunlight should be avoided to prevent sunburn damage to the leaves. During the growing period, ensure that Sedum rubrotinctum 'Aurora' receives sufficient sunlight.

Ventilation: Sedum rubrotinctum 'Aurora' requires a certain ventilated environment to ensure good growth.

Soil: Sedum rubrotinctum 'Aurora' does not have high soil requirements; generally, as long as the soil is loose and has good drainage, it is fine.

Watering: Sedum rubrotinctum 'Aurora' has a certain drought tolerance, but during its growing period, a certain amount of moisture must be ensured so that it can grow better. Generally, if Sedum rubrotinctum 'Aurora' grows slowly or its leaves show a sun-red color, it indicates a lack of water. At this time, follow the plant watering principle of “do not water until dry, and water thoroughly when you do”.

Fertilizing: Sedum rubrotinctum 'Aurora' has no great requirements for fertilizer; applying a light fertilizer once or twice during the growing period is enough.

Pruning: Sedum rubrotinctum 'Aurora' generally becomes messy after being grown for more than three years, so pruning should be done in advance to maintain its shape.

Precautions for Growing Sedum rubrotinctum 'Aurora'

1. Leaf drop in Sedum rubrotinctum 'Aurora' generally occurs only under pest and disease conditions, and it is prone to leaf spot disease, stem rot, and so on. If it is leaf spot disease, it is mainly caused by poor ventilation; ventilation can be strengthened, and systemic fungicides can be used for control.

2. Sometimes Sedum rubrotinctum 'Aurora' also encounters stem rot, which can also cause leaf drop. When this happens, it is generally caused by dampness. At this time, healthy stem sections from the upper part of the plant should be cut for propagation, while avoiding excessive and frequent watering in winter, and keeping the potting soil slightly dry.

Differences Between Sedum rubrotinctum 'Aurora' and Sedum rubrotinctum 'Aurora' Variegata

When it comes to the differences between Sedum rubrotinctum 'Aurora' and Sedum rubrotinctum 'Aurora' Variegata, many succulent fans probably cannot distinguish them because they have not seen both plants at the same time. In fact, the gap between the two is still quite large. Next, let me introduce the differences between them.

Sedum rubrotinctum 'Aurora' Variegata, a variegated cultivar of Sedum rubrotinctum 'Aurora', has patterned leaves with white powder. When colored up, it appears pink; when not colored up, it looks whitish because of low chlorophyll.

Sedum rubrotinctum 'Aurora' is green when not colored up, with a glossy surface and no white powder, and turns reddish-brown under conditions of sufficient sunlight.
