Type of Plant
It is a type of succulent plant, which means it has adapted to arid climates by evolving thick, fleshy leaves to store water, so it can survive a long time without rain or water.
The most attractive feature of Echeveria gigantea is the tall flowering stalk that sprouts up from the rosette at certain times of the year.
Mainly found in the states of Puebla, Michoacán, and Oaxaca, typically in arid, rocky terrain with limited water availability.
Echeveria gigantea is unique in our green roof because it is the largest of the Echeveria!

Brief Description:
Echeveria gigantea is a succulent plant native to Mexico, one of the larger plants in the genus Echeveria. It's stem can grow up to 50 cm long, and it has a semi-dense rosette up to 60 cm in diameter. It's leaves have a rounded apex, and are green with reddish tones. It sprouts flowers from a tall stalk in the late autumn and early winter months.
It can help decrease soil erosion in arid and rocky environments. It helps with water conservation, and the shade from its leaves helps provide shelter from the sun for small organisms like insects. Its flowers also attract pollinators such as bees, butterflies, and hummingbirds.
This succulent has ornamental value as decoration in gardening and landscaping.
This is the largest plant of the Echeveria genus, known for its beautiful rose shape and native to only small areas in Mexico. The genus is named for Atanasio Echeverría y Godoy, who discovered and recorded many species of plants and animals in Mexico in the late 18th century.
Plants make energy for themselves though the process of photosynthesis, where the plants use energy from the sun as well as water and carbon dioxide to produce oxygen and glucose, which is where they get their energy.
Additionally, plants "breathe" at night through the process of cellular respiration, which is the reverse of photosynthesis. They use the glucose and oxygen and release water vapor and carbon dioxide through their stomata.
Arid, rocky lands with low water availability/rainfall, and typically in high altitude. Here you would find many other succulents, including agaves and other Echeveria, as well as nopales and shrubs.
It provides food for consumers, shelter for insects and small animals, helps conserve water, and attracts pollinators.
While Echeveria gigantea does not have a listed conservation status, its small habitat is in danger and requires conservation. Practices like agriculture, deforestation, and urbanization are decreasing its habitat and endangering it.
Strategies like habitat preservation, sustainable land management practices, or cultivating in gardens like our green roof!
Its thick leaves allow it to store water efficiently, which is important in its dry climate. Moreover, the stomata, which control water loss, close during the day to keep water from evaporating.
Its stomata and thick leaves adaptations allow it to survive better than other plants. Nature selected for these traits, leading to the eventual development of the species.
