Colocasia, commonly known as elephant ears, makes a striking addition to a patio! With its bold, architectural foliage, it brings an instant tropical feel to outdoor spaces. These plants prefer a position in partial shade or dappled sunlight — too much direct sun can scorch their large leaves, while deep shade can limit growth. Colocasia thrives in warmth and should only be placed outside once all danger of frost has passed, typically from late May or early June. They are not frost-hardy, so it’s essential to bring them indoors or lift and store the tubers before the first autumn frosts arrive.
On the patio, Colocasia does best in large containers filled with rich, moisture-retentive soil. They are heavy feeders and drinkers, so regular watering is essential to keep the soil consistently moist — they can even tolerate standing in a shallow tray of water. Feeding every two to three weeks with a high-nitrogen fertiliser during the growing season will help support vigorous leaf growth. Their dramatic leaves can catch the wind, so sturdy pots and a sheltered location are ideal. While they are showy and rewarding, it’s worth noting that some varieties can cause skin irritation or be harmful if ingested, so caution is advised around pets and children. Overall, Colocasia can be a stunning feature on a summer patio, provided they are kept warm, well-fed, and protected from the cold.
