Description
Echeveria australis is a sparingly branched succulent shrub with stout glaucous branches bearing somewhat glaucous and often purplish leaves. The branches are up to 12 inches (30 cm) long or up to 24 inches (60 cm), including the inflorescence. Leaves are obovate or spatulate, rounded or abruptly acute at the tip, thickly set at the apex of branches, and early falling off below. They are up to 2.8 inches (7 cm) long and 1.2 inches (3 cm) wide, progressively smaller along the flowering stems. Flowers are bright red, bell-shaped, and appear in terminal clusters in winter.
Etymology
The specific epithet "australis (aw-STRAL-iss)" is a Latin adjective meaning "southern" and refers to the relatively southern distribution concerning the bulk of the genus.
How to Grow and Care for Echeveria australis
Light: E. australis prefers full sun to partial shade. If you are moving your plant outside in the spring, do it gradually. The intense afternoon sun can cause sunburn. During the winter, when your E. australis is inside, put it near the brightest window in your home. It will stretch if it does not have enough sunlight.
Soil: This succulent needs a potting soil mix that drains quickly. Many growers will create their own mix. However, commercial succulent potting mixes will work fine.
Temperature: This plant is a tender succulent, which means it must be brought indoors for the winter to survive. E. australis can withstand temperatures as low as 30 °F (-1.1 °C). USDA Plant Hardiness Zones 10a to 11b, 30 to 50 °F (-1.1 to 10 °C).
Watering: Provide moderate amounts of water from spring to fall. The "soak and dry" method is the preferred schedule for watering E. australis. If you have saucers under the pots, make sure after a short time to empty the water. Water your plant just enough to keep it from shriveling during the winter months.
Fertilizing: E. australis grows well without fertilizer but may benefit from the extra nutrients. Use a slow-release fertilizer in spring or a liquid fertilizer diluted 2 to 4 times more than usual and used less often than recommended.
Repotting: Repot the plant only as needed during spring or early summer when it is actively growing. To repot your E. australis, ensure the soil is dry before repotting.
Propagation: This succulent is usually propagated from leaves or stem cuttings. Spring is the best time to take leaf cuttings.
