The donkey ear plant, scientifically named Kalanchoe Gastonia-bonnier, is a flowering plant. This plant originates from the island of Madagascar. The name Donkey ear plant comes from the shape of its leaves, which resemble a donkey’s ear. Another common name this plant has is Palm Beachbells.

This plant’s leaves are thick, waxy coated, deep green with brown spots. The leaves can grow 20 inches (51 cm) long. This greenie is a fast-growing succulent. New plantlets form at the end of the leaves and weigh them down or drop to the ground by themselves. In fall and early winter, this plant will flower, producing tall beautiful red or yellow flowers. The flowers can grow to a height of about 7.9 inches (20 cm). 

How To Grow?

You can plant and grow this succulent outside in the USDA Hardiness zones ten to twelve. This greenie loves warm weather, the ideal temperature for it to thrive would be around 85 °F (30 °C). If the temperature won’t drop below 55 °F (12.8 °C) the plant should grow and live just fine.

Donkey ear plant leaves contain compounds that can be harmful to humans and pets if ingested in large amounts. Keep the plant from the reach of children and pets. 


The Donkey ear plant is rather easy to care for due to its low water requirements. In the summer, when the temperatures rise, water your succulent once a week. In the winter, when the temperatures drop, water the plant once or twice a month. The watering frequency depends on the rate of evaporation. To be even more precise, wait for the potting mix’s top two inches (5 cm) to dry in-between watering.

Indoors place it near a window, in a garden place it far from the shades of other plants and buildings. When first planting this greenie make sure to not place it directly under the sun. Place it somewhere with partial shade and over time as it grows move it to a full sun spot. This way your succulent won’t dry up and get sunburned. 

Soil And Fertilizer

If the succulent is healthy it shouldn’t need any fertilizer. However, if you can’t grow the plant with the needed requirements fertilizer is a great way to help your plant thrive. Mix an all-purpose fertilizer with its recommended amount of water and use that instead of plain water. Water with that mix every two to three months.

  • Plant the cutting into the soil;
  • Place the container with the cutting somewhere it can get enough light;
