Giant Velvet Rose Aeonium hierrense
ABOUT
Aeonium hierrense, known as the Giant Houseleek, displays a distinctive rosette pattern that is typical of the Aeonium genus. It bears fleshy, spoon-shaped leaves which are glossy and often have a waxy coating, enhancing their succulence. These leaves can exhibit shades of green, often with a hint of blue or purple, and occasionally feature a reddish tint around the margins, particularly when exposed to sunny conditions. The leaves are arranged in a symmetrical pattern, emerging from a central point, and can vary in color intensity depending on the amount of sunlight the plant receives. As the plant ages, the lower leaves may wither and drop, enabling the plant to direct its energy towards new growth. The Giant Houseleek usually has a branched, tree-like stem that supports the weight of the rosettes and gives the plant its architectural appeal. This succulent can also produce large conical clusters of small, starry flowers on tall stems that rise above the foliage, though it blooms infrequently. These flowers can be yellow or pale green, adding a dash of color to its striking foliage. Overall, the aesthetic of Aeonium hierrense is that of a sculptural, highly ornate plant that stands out for its rosette-forming habit and robust appearance.

WaterThe Aeonium hierrense, commonly known as Giant Aeonium, should be watered deeply but infrequently, allowing the soil to completely dry out between waterings. In general, watering once every 7 to 10 days during the active growth season in spring and summer is sufficient. During the winter dormancy period, reduce watering to once a month. Each watering session should provide enough water to soak the soil thoroughly, which can be approximately 16 ounces for smaller pots or up to 1-2 gallons for larger containers, depending on the size of the plant and pot.
LightGiant Aeonium prefers a spot with bright, indirect sunlight or partial shade. It can tolerate full sun in cooler coastal areas but in hotter climates, it should be protected from the harsh afternoon sun which can scorch its leaves. A location that receives morning sunlight and afternoon shade would be ideal for this succulent.
TemperatureThe Giant Aeonium thrives best in temperatures between 40 to 100 degrees Fahrenheit; however, it can survive brief periods outside this range. The ideal temperature conditions are mild, ranging from 65 to 75 degrees Fahrenheit. It is not frost hardy, so if the temperature is expected to drop below 40 degrees Fahrenheit, it is crucial to protect the plant or bring it indoors.
PruningPruning the Giant Aeonium is necessary to remove any dead or damaged leaves and to maintain its attractive appearance. It is best pruned in the spring or early summer, which is the beginning of its active growth period. Pruning can be performed annually or as needed when you notice parts that require removal. Always use clean, sharp scissors or pruning shears to make precise cuts.
CleaningAs needed
SoilThe Giant Houseleek thrives best in a well-draining soil mix that is composed of equal parts coarse sand, perlite, and regular potting soil. Aim for a slightly acidic to neutral pH range between 6.0 to 7.5 for optimal growth.
RepottingThe Giant Houseleek should be repotted once every two to three years to provide it with fresh soil and to accommodate its growing size. Ensure to use a well-draining soil mixture during repotting.
Humidity & MistingThe Giant Houseleek prefers moderate humidity levels, however, it is quite adaptable and can tolerate lower humidity environments typical of most homes as long as it's not too dry.

Life cycleThe life of Aeonium hierrense, commonly known as Giant Velvet Rose or Hierro Giant Houseleek, begins with seed germination, which requires well-draining soil and appropriate moisture levels. Upon sprouting, the seedling emerges and develops into a rosette with fleshy, spoon-shaped leaves. As a perennial, the plant enters a juvenile phase, growing larger each year, with some rosettes spanning up to 60 centimeters in diameter. It achieves maturity within a few years, at which point it may produce a tall, conical flower spike bearing clusters of small, star-shaped flowers, typically yellow in color. After flowering, which occurs once in the plant's lifetime, the individual rosette that has bloomed will die, but the plant can continue to live and propagate through offsets. Over the years, the plant maintains a cycle of producing new rosettes, flowering, and dying, with propagation ensuring its continuation.
PropogationPropogation time
Spring-Early Summer
The Aeonium hierrense, commonly known as the Giant Houseleek, can be propagated effectively through the use of stem cuttings. This method is popular due to its simplicity and high success rate. To propagate, a healthy stem cutting of about 2 to 4 inches (5 to 10 cm) is selected and cleanly cut from the parent plant, ideally during the growth season in spring or early summer. The cutting should then be allowed to dry and callous over for several days to prevent rotting when planted. Once calloused, the cutting is placed in well-draining soil and given minimal water until roots develop, after which it can be watered regularly. This method leverages the plant's natural ability to form roots from cut tissue and typically results in a new, independent plant within a few weeks to a few months.
