Perilla, also known as Perilla frutescens, is a versatile plant that is commonly grown as an annual in many regions. However, it is technically a tender perennial, meaning that it is capable of surviving year-round in areas with mild winters.
In terms of appearance, perilla bears a resemblance to coleus, with its vibrant and colorful foliage. The leaves of perilla come in various shades of green, purple, and burgundy, adding a striking visual appeal to gardens and landscapes. This plant typically forms a compact mound, reaching heights of 2-3 feet and spreading to a similar width. However, with regular pinching, it can be kept smaller and more compact.
One of the reasons why perilla has gained popularity as an annual is its ability to add a splash of color and texture to containers, borders, and beds. Its attractive foliage can serve as a focal point or complement other plants in a mixed arrangement. Additionally, perilla is also known for its ornamental value in ornamental herb gardens and Asian-inspired landscapes.
Although perilla is typically grown as an annual, it can be overwintered in certain climates. In regions with mild winters, where temperatures do not drop below freezing, perilla can survive and continue to grow year after year. However, in areas with colder winters, perilla may not survive the frost and will need to be replanted each spring.
Personally, I have had experience growing perilla in my garden as both an annual and a perennial. In my area, perilla is not able to withstand the harsh winters, so I treat it as an annual and replant it each year. However, I have friends who live in more temperate regions where perilla has successfully overwintered and grown as a perennial in their gardens.
To summarize, perilla is technically a tender perennial but is commonly grown as an annual in many regions. Its eye-catching foliage and compact growth habit make it a popular choice for adding color and texture to gardens and landscapes. While it can be overwintered in mild climates, it is generally treated as an annual in areas with colder winters.
